Stock Analysis in Excel: Build an Auditable Workbook
A stock-analysis workbook organizes inputs, formulas and research decisions in separate sheets. Excel can support a small watchlist or custom calculation, but visible formulas alone do not guarantee correct data. This page explains a workbook structure; it does not provide a downloadable template or report a tested investment result.
Key Takeaways
- Keep raw inputs, calculations and decisions separate, with source and reporting dates.
- Data connectors may require eligible subscriptions or additional access; Excel is not a universally free data feed.
- A rolling average and Wilder RSI use different calculation methods.
- Mark unavailable values explicitly rather than letting blank cells silently pass a screen.
- A conditional-formatting signal is a rule match, not evidence of expected profit.
Use Separate Sheets for Inputs and Decisions
Create an Inputs sheet with symbol, exchange, currency, timestamp, source and raw values. Keep price observations separate from financial-statement periods. Preserve downloaded files or retrieval details so that another reviewer can reproduce the inputs. Use a Calculations sheet for formulas, a Watchlist sheet for criteria and results, and a Holdings sheet for position quantities and cost information. If combining multiple currencies, show the conversion rate and date. A current-value minus purchase-value figure is not a full portfolio return when there are deposits, withdrawals, dividends or fees. Add an Exceptions sheet for missing fields, duplicate dates, stale quotes and unmatched symbols. Review it before relying on a green or red cell.
Check Formulas at the Boundaries
For fifty valid, sequential closing observations in B2:B51, =AVERAGE(B2:B51) computes their simple average. It does not guarantee fifty trading days if rows are missing, duplicated or include another symbol. Excel’s treatment of blanks and text can hide an incomplete window, so check the observation count separately. Wilder RSI uses smoothed average gains and losses, seeded from an initial period. AVERAGEIF over only positive or negative observations is not an equivalent implementation because it changes the denominator and omits the recursive smoothing. Define zero-loss and flat-series behavior, then compare the result with a documented reference. Choose STDEV.P or STDEV.S according to the intended definition. Standard deviation of price levels used in a band is not the same as return volatility. MAX and MIN require an explicitly selected historical window to represent a 52-week range. For lookups, require an exact symbol match and a visible missing-value result.
Connect Data with Known Access and Timing
Microsoft’s STOCKHISTORY retrieves historical instrument data and requires an eligible Microsoft 365 subscription. Check supported instruments and output fields before building formulas around it. It is not a universal live execution feed. Google Sheets has GOOGLEFINANCE, whose quotes can be delayed by up to twenty minutes and whose exchange coverage is limited. It is not an Excel function; exporting a spreadsheet does not create a native refreshing Excel connection. CSV imports and provider APIs are other options, subject to their current download rights, rate limits and fees. Do not assume every Yahoo or FMP dataset is free or that every ticker is available. Record the acquisition method and preserve the last successful refresh time.
Build a Screen You Can Explain
Choose a documented universe and criteria, then calculate pass, fail or unavailable for each criterion. A hypothetical valuation-and-momentum screen is a research filter, not a claim that a particular set of stocks will outperform. Save the filter version and data date with the output. Keep missing or negative earnings separate from a low positive P/E ratio. Distinguish annual revenue growth from trailing-period growth. If ranking with a composite score, show weights and normalization instead of hiding them in formatting. There is no measured five-stock scan or three-out-of-five success rate behind this page. Such a result would need the saved universe, observation dates, benchmark and calculation method.
Evaluate a Template Before Paying or Adapting It
Inspect formulas, locked cells, external connections, refresh behavior and required Excel version. Test a small known input set, including missing values and zeros. Price alone does not establish a template’s reliability, and no free-versus-paid test is claimed here. Pineify’s AI Stock Picker provides an interface to available provider stock data and scores. A workbook offers control over custom calculations. Neither is inherently faster or more accurate for every task. If combining them, preserve the score’s source, scale and timestamp rather than assuming it refreshes with each market tick.

Frequently Asked Questions
Is there an Excel template to download here?
No. This page describes a workbook structure and calculation checks. It does not offer a tested downloadable workbook.
Does Excel include free live stock data for every ticker?
No. Function availability, subscriptions, instrument coverage and data terms vary. Verify the connector and its update timing.
Can I calculate RSI with AVERAGEIF alone?
That does not reproduce Wilder’s smoothed RSI. Use a documented seed and recursive smoothing, including explicit zero-loss and flat-series handling, then compare against a reference.
Does GOOGLEFINANCE keep working as an Excel data connection?
GOOGLEFINANCE is a Google Sheets function. An export does not establish an equivalent refreshing native Excel connection; choose a supported Excel source or a documented import process.
How should a missing P/E ratio affect a screen?
Treat it as unavailable under an explicit rule. Do not replace it with zero and accidentally classify it as a cheap stock. Negative earnings require separate interpretation.
Are paid templates more reliable?
Not necessarily. Review formula definitions, data sources, error handling and compatibility. Test known inputs before relying on any workbook.
