Building a Sector Rotation Dashboard with Excel: Formulas and Charts for Performance Tracking

You don’t need expensive platforms to spot sector shifts — Excel can do it.
This guide shows how to build a refreshable sector rotation dashboard in Excel that pulls sector ETF prices, computes 3-, 6-, and 12-month momentum, compares each sector to SPY, ranks leaders and laggards, and paints the results as charts and a heatmap.
You’ll use Power Query, dynamic arrays, PivotCharts, and simple formulas — no macros required.
Follow the step-by-step sequence and you’ll have a daily-refresh tracker that tells you which sectors are beating the market.

Immediate Steps to Build Your Excel Sector Rotation Dashboard

Your finished dashboard pulls sector ETF prices automatically, calculates 3, 6, and 12 month momentum for each sector, ranks them against a benchmark like SPY, highlights leaders and laggards with color, and refreshes with a single click. You’ll use Microsoft 365 Excel (2016 or later recommended) for Power Query, dynamic arrays, PivotCharts, and slicers. No macros required, though Power Query needs an internet connection for API or web imports.

The dashboard tracks 11 standard U.S. sector ETFs (XLK, XLF, XLU, XLY, XLE, XLV, XLI, XLB, XLP, XLC, and XLRE) plus SPY as your benchmark. Build it once, refresh it daily or weekly, and watch which sectors are rotating into strength or weakness.

Here’s the complete build sequence:

1. Import price data via Power Query (Data > Get Data > From Web) or STOCKHISTORY for each ticker, pulling Date, Close, and Volume columns into a single normalized table.
2. Organize the table with columns Date | Ticker | Sector | Close | Volume so every row is one ticker date observation.
3. Calculate daily returns (=Closetoday/Closeyesterday, 1), then rolling 3 month (~63 trading days), 6 month (~126 days), and 12 month (~252 days) momentum using formulas like =(Closetoday / INDEX(Closecolumn, ROW(), 63)), 1.
4. Compute relative strength by dividing each sector’s return by SPY’s return for the same period, then rank sectors with =RANK.EQ(momentumvalue, momentumrange, 0).
5. Build charts: line charts for sector trends over time, a ranked horizontal bar chart for current momentum, and a heatmap table with conditional formatting color scales.
6. Add interactivity by converting data to an Excel Table, inserting a PivotTable and PivotChart, then adding Slicers for date range and sector selection plus Data Validation dropdowns to switch lookback windows (3M/6M/12M).
7. Automate updates by scheduling Power Query refresh (Data > Refresh All) and using structured table references so new rows flow into charts without manual range edits.

Each step layers a new capability (data in, metrics out, visuals live, filters dynamic) so you move from raw prices to ranked sector signals in about two hours. The lookback windows (63, 126, 252 trading days) match industry standard momentum periods, and the benchmark comparison answers the key question every rotation strategy needs: which sectors are beating the market right now, and by how much?

Pros & Cons of Building a Sector Rotation Dashboard in Excel

Excel offers speed and flexibility for retail traders and small teams who need a custom rotation tracker without the cost or learning curve of dedicated portfolio software. The platform already lives on your desktop, connects to free and paid data feeds, and lets you prototype formulas, charts, and conditional rules in minutes.

Pros:

Power Query automation refreshes data from APIs, CSV files, or web tables with one click, eliminating manual copy paste.

STOCKHISTORY function (Microsoft 365) pulls historical prices for any ticker directly inside a cell. No external file required.

Slicers and PivotCharts give point and click filtering by date, sector, or custom dimension without writing code.

Dynamic arrays (FILTER, SORTBY, UNIQUE) let you build live ranked lists and top N tables that update instantly when source data changes.

Conditional formatting heatmaps turn a boring table into a visual strength map with red to green color scales and icon sets applied via simple rules.

Cons:

Not real time. Refresh frequency depends on your data source. Most free APIs update once per day, and STOCKHISTORY lags by at least 15 minutes.

API rate limits restrict the number of calls per minute or day, so pulling 12 tickers every five minutes will hit most free tier caps quickly.

Large datasets slow performance. Tracking 20 sectors over 10 years at daily frequency (50,000+ rows) can make PivotTables and charts sluggish on older machines.

Data accuracy disclaimers apply. Prices may come from OTC desks or market makers rather than direct exchange feeds, and redistribution is typically prohibited under provider terms.

Manual schema changes break structured references if you later add columns or change table names, requiring formula audits across worksheets.

Use Excel when you want full control over formulas and layout and can tolerate a daily or weekly refresh cycle. Skip Excel if you need tick by tick data, want to backtest thousands of parameter combinations, or plan to share live dashboards with a large team (in which case Power BI or Tableau scale better).

Understanding Sector Rotation Data Inputs for Excel Dashboards

Sector rotation dashboards start with a normalized price table: every row represents one ticker on one date, and every column holds a consistent data type (date, string, number). The recommended structure uses six core columns (Date, Ticker, Sector, Close, Volume, and AdjustedClose). This layout supports multi ticker analysis in a single table and feeds PivotTables, charts, and formulas without reshaping.

Import methods include Power Query “From Web” (Data > Get Data > From Web, paste an API endpoint like https://api/endpoint?symbol=XLK&from=2020-01-01&to=2024-01-01&apikey=YOUR_KEY, then load the JSON or CSV response into Excel), CSV file imports (downloaded bulk histories from Yahoo Finance, Alpha Vantage, or Quandl), and the STOCKHISTORY function for Microsoft 365 users (=STOCKHISTORY(“XLK”,”1/1/2020″,”12/31/2023″,0,0) pulls daily data directly into a spill range). Power Query offers scheduled refresh and transformation steps (filtering columns, changing data types, appending multiple tickers), while STOCKHISTORY is instant but limited to tickers recognized by Microsoft’s provider.

Standard financial data providers for sector ETF histories include Yahoo Finance (free CSV download or yfinance Python library export), Alpha Vantage (free API key, 5 calls/minute, 500/day limit), Quandl/Nasdaq Data Link (free tier includes EOD equity data), IEX Cloud (tiered API with sandbox environment), Twelve Data (real time and historical via REST API), and EODHD (End of Day Historical Data, paid plans start around $20/month).

Choose a provider that matches your refresh cadence (daily is typical for rotation strategies) and budget, then design your import to land in the Date | Ticker | Sector | Close | Volume | AdjustedClose format so downstream formulas reference consistent column names.

Key Sector Rotation Metrics Used in Excel

Sector rotation strategies compare relative performance across sectors to identify which areas of the market are gaining or losing momentum. The core metrics (period returns, rolling momentum, relative strength, and z scores) quantify that performance in ways Excel formulas can rank and visualize.

Period returns measure the percentage change in price over a fixed window. A daily return is =B2/B1, 1 (today’s close divided by yesterday’s close, minus one). A 3 month momentum calculation on monthly data looks back roughly three rows: =(C2/C5), 1. For daily data, 3 months equals about 63 trading days, so the formula becomes =(C2 / INDEX(C:C, ROW(), 63)), 1, which divides today’s price by the price 63 rows up. Six month momentum uses 126 trading days, twelve month uses 252. These lookback windows align with calendar quarters and the standard trading year (252 business days per year).

Relative strength (RS) compares a sector’s return to a benchmark return, typically SPY or the broad market index. The RS ratio is =SectorReturn / BenchmarkReturn. A value above 1.0 means the sector outperformed. The RS difference is =SectorReturn, BenchmarkReturn, showing the percentage point spread. If XLK returned 8 percent and SPY returned 5 percent, the RS ratio is 1.6 and the RS difference is +3 percentage points. Ranking sectors by RS ratio or difference reveals current leadership.

Z scores standardize momentum across sectors by measuring how many standard deviations a sector’s current momentum sits above or below its historical average. The formula is =(Value, AVERAGE(range)) / STDEV.P(range). For example, if XLE’s 12 month momentum is 15 percent, the average over the past 24 months was 8 percent, and the standard deviation was 5 percent, the z score is (15, 8) / 5 = 1.4. A z score above +1 signals strong momentum; below, 1 signals weakness. This normalization lets you compare sectors with different baseline volatilities on a single scale.

Six essential formulas every beginner must know:

Daily return: =B2/B1, 1

Cumulative return over range: =PRODUCT(1 + C2:C64), 1 (adds 1 to each daily return, multiplies them together, subtracts 1)

3 month rolling momentum (daily data): =(C2 / INDEX(C:C, ROW(), 63)), 1

RS ratio vs benchmark: =([@SectorReturn] / [@BenchmarkReturn])

RS difference: =([@SectorReturn], [@BenchmarkReturn])

Z score: =([@Momentum], AVERAGE(Table[Momentum])) / STDEV.P(Table[Momentum])

These formulas feed ranking, conditional formatting, and chart data ranges, turning raw prices into actionable rotation signals.

Core Excel Tools Used When Building Sector Rotation Dashboards

Power Query (Data > Get Data > From Web, From File, From Database) automates data import and transformation. You define a query once (connect to an API endpoint or CSV file, filter columns, change data types, merge ticker lookups) and then refresh it with one click (Data > Refresh All) or on a schedule if you publish to Excel Online. Power Query outputs land in Excel Tables, which auto expand when new rows arrive, so formulas and charts referencing Table[Close] or Table[Momentum] never need manual range updates. This eliminates the copy paste cycle and ensures every refresh propagates through your dashboard instantly.

Structured tables (Insert > Table or Ctrl+T) anchor the entire workflow. When you convert a range to a table, Excel assigns a name (e.g., SectorData) and column headers become structured references: [@Close] means “this row’s Close value,” Table[Close] means “the entire Close column.” Formulas using structured references adjust automatically when you add or delete rows. Dynamic arrays (FILTER, SORTBY, UNIQUE, LET) build on tables by letting you write one formula that spills ranked or filtered results into multiple cells. For example, =SORTBY(Table[Sector], Table[Momentum], ,1) returns all sectors sorted by momentum descending, updating live as momentum changes.

PivotTables (Insert > PivotTable) summarize table data by sector, date, or any dimension you drag into rows, columns, or filters. Insert a PivotChart from the PivotTable to visualize aggregated returns or momentum, then add Slicers (PivotTable Analyze > Insert Slicer) for point and click filtering by year, sector group, or custom category. Slicers connect to the PivotTable and instantly filter both the table and the chart, giving users dropdown free interactivity. Combine slicers with Data Validation dropdowns (Data > Data Validation > List, source “3M,6M,12M”) to let users switch lookback periods, and use INDIRECT or CHOOSE formulas to feed the selected period into chart data ranges dynamically.

Essential Excel tools summarized:

Power Query for automated, repeatable data import and refresh from APIs, CSVs, or web tables.

Excel Tables (structured references) so formulas and charts auto expand with new data rows.

Dynamic arrays (FILTER, SORTBY, UNIQUE) to build live ranked lists and top N tables without helper columns.

PivotTables and PivotCharts to aggregate and visualize multi dimensional data (sector × date × momentum).

Slicers and Data Validation to add interactive filters and dropdown controls that update charts instantly.

These five tools turn static spreadsheets into refresh and go dashboards, where one Data > Refresh All click pulls new prices, recalculates momentum, re ranks sectors, and updates every chart and heatmap without touching a formula.

How to Build a Sector Rotation Dashboard with Excel (Step by Step)

Importing Sector ETF Data into Excel

Use Power Query or STOCKHISTORY to pull historical prices for your sector ETF universe (XLK, XLF, XLU, XLY, XLE, XLV, XLI, XLB, XLP, XLC, XLRE) and benchmark (SPY). For Power Query, follow these five steps:

1. Open Power Query: Data tab > Get Data > From Web (or From File if you downloaded CSVs).
2. Enter the API or file URL: paste an endpoint like https://api/endpoint?symbol=XLK&from=2020-01-01&to=2024-01-01&apikey=YOURKEY (replace YOURKEY with your actual API key from Alpha Vantage, IEX Cloud, or similar provider), or browse to a local CSV file.
3. Transform the data: Power Query Editor opens. Select only the columns you need (Date, Close, Volume), rename them if necessary (right click column header > Rename), and ensure Date is formatted as Date type and Close as Decimal Number.
4. Append additional tickers: if your API returns one ticker per call, click Home > Append Queries > New Source, repeat the From Web step for XLF, XLU, etc., and stack all results into one table; add a custom column “Ticker” with the ticker symbol so you can distinguish rows later.
5. Load to Excel Table: click Close & Load (or Close & Load To if you want to specify the worksheet and cell), which creates a Table object on your chosen sheet; name the table “SectorData” via Table Design > Table Name so formulas can reference SectorData[Close] cleanly.

For STOCKHISTORY (Microsoft 365 users), enter =STOCKHISTORY(“XLK”,”1/1/2020″,”12/31/2023″,0,0) in cell A2, copy down for each ticker (change “XLK” to “XLF”, “XLU”, etc.), and the function spills Date and Close columns to the right. Combine all tickers into a single table by stacking the spill ranges and adding a Ticker column manually, then convert the range to a Table (Ctrl+T).

Define your date ranges to capture at least 252 trading days (one year) before your analysis start date if you plan to calculate 12 month momentum, and extend to today or the most recent trading day. Typical windows for rotation strategies are 63 trading days (≈3 months), 126 (≈6 months), and 252 (≈12 months), so ensure your import spans the current date minus 252 days at minimum to avoid #N/A errors in rolling formulas.

Organizing and Cleaning Data

Convert your imported range to an Excel Table (select any cell in the range, press Ctrl+T, check “My table has headers”). Name the table SectorData (Table Design > Table Name). Your table needs six core columns:

Date: sorted oldest to newest, formatted as Date (Home > Number Format > Short Date).

Ticker: text, e.g., “XLK”, “XLF”, “SPY”.

Sector: text label, e.g., “Technology”, “Financials”, “Benchmark” (add this column if your source doesn’t provide it; use a VLOOKUP or manual mapping table Ticker → Sector).

Close: adjusted close price, formatted as Number with two decimals.

Volume: integer, formatted as Number with zero decimals or use Number > Thousands separator.

AdjustedClose: if your source separates raw close from adjusted close (splits/dividends applied), include both; otherwise Close = AdjustedClose.

Add calculated columns inside the table for returns and momentum. Insert a new column header “DailyReturn” and in the first data row (assuming row 2) enter =[@Close] / INDEX(SectorData[Close], ROW(), 1), 1. This divides today’s close by yesterday’s close (one row up) and subtracts one to get the percentage change. Copy the formula down; Excel’s structured references adjust automatically. For 3 month momentum, add a column “Momentum3M” with formula =([@Close] / INDEX(SectorData[Close], ROW(), 63)), 1. For 6 month, “Momentum6M” with ROW(), 126. For 12 month, “Momentum12M” with ROW(), 252. The INDEX function looks up the close price exactly 63, 126, or 252 rows earlier in the same ticker’s series (you may need to filter or sort by Ticker and Date ascending first to ensure rows align correctly; if mixing tickers in one table, consider a helper column that uses XLOOKUP to find the prior date’s close for the same ticker instead of relying solely on row offset).

Your cleaned table structure:

Date, Ticker, Sector, Close, Volume, AdjustedClose, DailyReturn (formula: =([@Close]/previous row Close), 1), Momentum3M (formula: =([@Close]/Close 63 days ago), 1), Momentum6M (formula: =([@Close]/Close 126 days ago), 1), Momentum12M (formula: =([@Close]/Close 252 days ago), 1).

Sort the table by Ticker (A to Z), then by Date (oldest to newest) using Data > Sort so ROW() based formulas find the correct prior row within each ticker’s history. If your table mixes all tickers in one column, use XLOOKUP or INDEX/MATCH with a date offset instead of ROW() to guarantee you’re comparing apples to apples.

Calculating Momentum and Relative Strength

Momentum formulas measure how much a sector’s price has changed over your chosen lookback window. Relative strength formulas compare that momentum to a benchmark, revealing which sectors are beating the market. Follow these four steps to add RS calculations:

1. Create a benchmark summary: filter SectorData to Ticker=”SPY” and calculate SPY’s 3M, 6M, and 12M momentum in separate columns or a summary table; for example, in a cell labeled “SPY_Momentum3M”, use =FILTER(SectorData[Momentum3M], SectorData[Ticker]=”SPY”) and take the latest row (or use a helper cell with =INDEX(FILTER(…), COUNTA(FILTER(…))) to grab the most recent value).
2. Add RS ratio columns: in SectorData, insert “RSRatio3M” with formula =[@Momentum3M] / $B$2, where $B$2 is the absolute reference to SPY’s 3M momentum; this divides each sector’s 3 month return by SPY’s 3 month return. Repeat for 6M and 12M. An RS ratio >1.0 means outperformance.
3. Add RS difference columns: insert “RSDiff3M” with =[@Momentum3M], $B$2 (the percentage point spread); repeat for 6M and 12M. Positive values indicate excess return over the benchmark.
4. Calculate z scores (optional, for advanced normalization): add a column “Momentum3M_ZScore” with formula =([@Momentum3M], AVERAGE(SectorData[Momentum3M])) / STDEV.P(SectorData[Momentum3M]). This standardizes momentum across all sectors and dates, showing how many standard deviations above or below the mean each observation sits. Z scores above +1 signal strong momentum; below, 1 signal weak momentum.

For ranking, use =RANK.EQ([@Momentum12M], SectorData[Momentum12M], 0) to assign each row a rank (1 = highest momentum, 2 = second highest, etc.). The third argument 0 sorts descending; use 1 for ascending. Add a “Rank12M” column with that formula, then apply conditional formatting to highlight top 3 (green) and bottom 3 (red) ranks.

Example RS ratio calculation: if XLK’s 12 month momentum is 0.25 (25 percent return) and SPY’s is 0.15 (15 percent), RSRatio12M = 0.25 / 0.15 = 1.67. XLK outperformed the benchmark by a factor of 1.67. The RS difference is 0.25, 0.15 = 0.10 (10 percentage points of excess return). Both metrics answer the same question (which sector beat the market?) with different units.

Creating Charts, Heatmaps, and Rankings

Visualizations turn tables of numbers into instant insights. Build five chart types to cover trend, comparison, distribution, and heatmap views:

Line chart (sector momentum over time): select Date and each sector’s Momentum12M column, Insert > Line Chart. Use one line per sector, different colors, and a legend. This shows which sectors have been trending up or down over the past year.

Ranked horizontal bar chart (current momentum snapshot): create a helper table with the latest date’s data (use FILTER or a PivotTable filtered to MAX(Date)), list Sector in rows and Momentum12M in values, sort descending, then Insert > Bar Chart. The longest bars are the strongest sectors right now.

Heatmap table (conditional formatting color scale): copy your sector momentum columns into a summary table (rows = sectors, columns = 3M/6M/12M momentum), select the range, Home > Conditional Formatting > Color Scales > choose a red yellow green scale. Green highlights high momentum, red highlights low. This is the fastest way to spot rotation visually.

Stacked bar or area chart (sector allocation or composition): if you track portfolio weights or sector market cap percentages, stack them in a bar or area chart to show how the mix shifts over time. Less common for pure momentum dashboards but useful for allocation decisions.

Sparklines (mini trend beside each sector row): in a column next to each sector’s name, insert a sparkline (Insert > Sparklines > Line, select the row’s historical momentum values as the data range). You get a tiny in line chart showing the trend at a glance.

For PivotCharts, insert a PivotTable (Insert > PivotTable) with Sector in Rows, Date in Columns (or Filters), and Momentum12M in Values (set to Average or Last value). Insert a PivotChart from the PivotTable (PivotTable Analyze > PivotChart), choose a Clustered Column or Line chart, then add Slicers (PivotTable Analyze > Insert Slicer) for Sector and Date. Users click slicer buttons to filter the chart instantly. No formula changes required.

Apply conditional formatting rules for ranked highlighting: select your Rank12M column, Home > Conditional Formatting > New Rule > Use a formula to determine which cells to format. For top 3, formula =[@Rank12M]<=3, format fill green. For bottom 3, formula =[@Rank12M]>=COUNT(SectorData[Rank12M]), 2, format fill red. This highlights leaders and laggards automatically as ranks update.

Automating Updates and Refresh Schedules

Automation ensures your dashboard stays current without manual intervention. Power Query queries refresh via Data > Refresh All or by right clicking the table and choosing Refresh. To schedule automatic refresh in Excel Online (OneDrive/SharePoint), open the workbook in the browser, click Data > Refresh All, then click the dropdown arrow next to Refresh All > Connection Properties > check “Refresh data when opening the file” and set a refresh interval if your Office 365 license supports scheduled refresh (typically requires Power BI or Excel Online with a data gateway for live connections). For desktop Excel, use a simple VBA macro (Developer > Visual Basic, insert a Workbook_Open subroutine with ThisWorkbook.RefreshAll) or an Office Script (Automate tab, record a script that clicks Refresh All, schedule it to run daily).

Four automation tips to keep your dashboard humming:

Use structured table references everywhere. Formulas like =SectorData[Close] auto expand when new rows arrive, so charts and PivotTables update without touching range definitions.

Separate raw and processed tables: load Power Query results into a “RawData” table, then reference RawData in calculated columns on a separate “ProcessedData” table; this prevents refresh from overwriting your formulas.

Test your refresh cycle: manually add a new day’s data, hit Refresh All, and verify every chart, rank, and conditional format updates correctly; fix any #REF or #N/A errors before automating.

Monitor API rate limits: if your provider caps you at 5 calls per minute, stagger your Power Query queries (manually refresh one at a time, or use Power Query’s built in retry/delay settings under Query > Advanced Editor to insert pauses between calls).

Store API keys in a separate “Config” worksheet cell and reference it in your Power Query M code (e.g., let ApiKey = Excel.CurrentWorkbook(){[Name=”Config”]}[Content]{0}[Column1] in …), so you can update the key in one place without editing every query. Document refresh frequency and last refresh timestamp in a dashboard header cell (=NOW()) so users know data freshness at a glance.

Comparing Excel Approaches Inside a Sector Rotation Dashboard

Ranking and scoring methods shape how your dashboard identifies leaders and laggards. RANK.EQ assigns integer ranks (1, 2, 3, …) based on a single metric like 12 month momentum; the sector with the highest momentum gets rank 1. SORTBY + dynamic arrays return a spilled list sorted by momentum descending, which you can slice with =TAKE(SORTBY(SectorData[Sector], SectorData[Momentum12M], ,1), 3) to extract the top 3 sectors in one formula. RANK.EQ fits traditional table layouts and conditional formatting rules (highlight if rank ≤3), while SORTBY excels when you want a live top N list in a dashboard summary cell or chart data range.

Momentum models vary in how they weight recent versus older performance. A simple 12 month return treats all 252 days equally. A weighted momentum score (for example, Score = 0.1×1M + 0.2×3M + 0.3×6M + 0.4×12M) gives more importance to longer term trends, smoothing out short term noise. Moving average crossovers (20 day MA crossing above 50 day MA) signal momentum shifts earlier than static lookback windows but require daily data and add complexity. Exponential moving averages (EMA) and weighted moving averages (WMA) apply declining weights to older prices, making them more responsive than simple moving averages (SMA). Choose EMA if you want to catch momentum changes quickly; choose SMA or fixed window returns if you want stability and simplicity. For sector rotation, most practitioners stick with fixed 3M/6M/12M momentum plus RS ratio because the formulas are transparent and the signals are easy to backtest.

Experiment with both methods side by side. Add a “RankMethod” dropdown in your dashboard (Data Validation list: “RANK.EQ,SORTBY”), then use an IF or CHOOSE formula to toggle which ranking logic feeds your top sector list. Track which method produces fewer false signals or higher Sharpe ratios over your backtest period, then standardize on that approach for live use.

How to Use a Sector Rotation Dashboard in Excel for Better Decisions

Interpretation starts with the current snapshot: which sectors rank in the top 3 by 12 month momentum and RS ratio, and which sit in the bottom 3? The dashboard’s ranked bar chart and heatmap answer this in seconds. If XLK, XLV, and XLI occupy the top three slots with 12 month momentum above 20 percent and RS ratios above 1.3, you know Technology, Health Care, and Industrials are beating the benchmark by a wide margin. If XLE, XLU, and XLF languish in the bottom three with negative momentum or RS ratios below 0.9, Energy, Utilities, and Financials are underperforming. A rotation strategy allocates capital to the top ranked sectors and underweights or exits the bottom ranked ones.

Timing and rebalancing frequency depend on your investment horizon and transaction costs. Monthly rebalancing is standard for rotation strategies. Recalculate ranks on the last trading day of each month, compare the new top 3 to last month’s holdings, and execute trades only when a sector drops out of the top 3 or a new sector enters. Weekly rebalancing increases turnover and trading costs but catches momentum shifts faster. Quarterly rebalancing reduces costs but lags trend changes. Use your dashboard’s date slicer to review historical rank changes month by month and measure how often the top 3 shuffles; if leadership changes every month, monthly rebalancing makes sense. If the same three sectors dominate for quarters at a time, quarterly rebalancing preserves more alpha after costs.

Performance comparison against SPY or another benchmark validates whether rotation adds value. Add a “Strategy Return” column that assumes equal weight allocation to the top 3 sectors each month, then calculate cumulative return using =PRODUCT(1 + StrategyReturn_range), 1. Compare that to SPY’s cumulative return over the same period. Compute annualized return (CAGR), Sharpe ratio (excess return divided by standard deviation of returns), and maximum drawdown (the largest peak to trough decline). If your rotation strategy delivers higher CAGR and Sharpe with similar or lower max drawdown, the dashboard is adding alpha. If not, refine your lookback windows, ranking weights, or sector universe.

Six example use cases for the dashboard once built:

Monthly rebalance: on the last trading day of each month, refresh data, note the top 3 sectors by 12M momentum, and reallocate portfolio to equal weight those three (or overweight top 1, underweight bottom 3).

Top N selection: set N=5 instead of 3 to diversify across more sectors while still avoiding the weakest; adjust your dropdown to “Top 5” and watch the ranked list update.

Benchmark comparison: filter the line chart to show only your selected sectors versus SPY; if your sectors’ lines run above SPY consistently, the rotation edge is visible.

Volatility filter: add a column for rolling 60 day standard deviation of daily returns; exclude any sector whose volatility exceeds a threshold (e.g., >25% annualized) even if momentum is high, reducing downside risk.

RS leadership rotation check: compare this month’s RS ratio ranking to last month’s; if a sector jumped from rank 8 to rank 2, investigate the catalyst (earnings, policy change, commodity price move) to understand whether the trend will persist.

Heatmap trend spotting: scan the 3M/6M/12M heatmap for sectors turning from red to yellow to green across columns. That color progression signals building momentum; conversely, green to yellow to red warns of fading strength before the rank officially drops.

Use the dashboard as a decision filter, not a black box. When a sector
