About AlphaStocks

Mission

AlphaStocks scores every stock the same way — five models, sector-calibrated weights, updated daily. We evaluate 1,595 companies across the S&P 1500 and top global ADRs through Graham, Buffett, Piotroski, Lynch, and Greenblatt and combine them into a single composite score from 0 to 10. No analyst opinions, no hidden methodology, no paywall on the scores themselves. Every score is transparent and fully documented.

Why We Built This

Free tools like Finviz, Yahoo Finance, and Morningstar give you raw data — dozens of ratios per stock, no framework for what they mean together. Paid services give you analyst opinions, but from a single methodology you can't verify. AlphaStocks sits between them — an algorithmic research tool that runs five independent models on 1,595 stocks daily and explains exactly why each stock scored the way it did.

We don't sell signals or make buy/sell recommendations. We show you which companies look fundamentally strong, fairly valued, and trending upward — and let you make your own decisions.

How It Works

Our composite score weighs four dimensions: Quality (40%) assesses profitability, financial health, and competitive moat using Piotroski and Buffett models. Value (10%) measures price attractiveness via Graham, Lynch, and Greenblatt models. Momentum (35%) tracks 6-month price trend relative to peers. Timing(15%) combines value and momentum to avoid value traps — cheap stocks that keep falling.

Scores are recalculated daily from SEC EDGAR filings and Alpaca Markets price data. Seven sector-specific profiles ensure banks aren't scored like tech companies and utilities aren't penalized for slow growth. Read the full methodology →

Backtest Results

We tested the scoring formula on historical data across three entry points (January 2021, June 2021, January 2022). A buy-and-hold portfolio of the top 10 highest-scored stocks delivered +8.4% annual alphaover the S&P 500 in the best case, with a 5-year total return of +185% vs SPY's +99%.

Across all three entry points, the formula consistently outperformed the benchmark, with annual alpha ranging from +4.4% to +8.4%. See full backtest results →
