How it works

From a legend's playbook to a ranked buy list.

No configuration. No formulas to memorize. Here is exactly what happens between picking a strategy and finding your next idea.

Pick a legend's strategy

Choose from dozens of published screens: Magic Formula, CANSLIM, Graham's net-nets and more. Each arrives preloaded with the master's exact rules, so there's nothing to configure.

Dozens of screens, one click

We do the math, daily

For every NASDAQ- and NYSE-listed stock we compute 60+ fundamentals from public filings (ROE, ROIC, earnings yield, PEG, the Piotroski F-Score and more) and refresh them each day. The weekend in Excel is gone.

3,800+ stocks · 60+ ratios

Every stock is scored & ranked

The strategy's rules become a single score from 0 to 100. Magic Formula, for instance, ranks the market on return on capital and on earnings yield, then combines the two ranks: the best of both worlds rises to the top.

0 to 100 fit score

You filter and compare

Narrow by sector, risk or one-year performance. Toggle the ratio columns you care about and sort any of them. Tabular figures keep every number aligned so you can scan a dense table without losing your place.

Study the backtest, then decide

See how the strategy held up over twenty years against the S&P 500 before you commit a dollar. GuruScreener finds the ideas and shows the evidence; the decision always stays yours.

Under the hood

How the score works, in plain English.

Step one

Normalize

Each metric is scaled from 0 to 100 across the whole universe, so a P/E and an ROE become directly comparable rather than apples and oranges.

Step two

Weight

The strategy blends its chosen metrics by importance: CANSLIM leans on earnings growth and relative strength; Buffett Quality leans on returns and low debt.

Step three

Rank

Stocks are sorted by their final score. Rank #1 is the stock that fits the strategy best today, not a recommendation but a starting point for research.

Worked example

Anatomy of a screen: the Magic Formula.

Rule 1: Cheapness

Earnings Yield

EBIT ÷ Enterprise Value

Rule 2: Quality

Return on Capital

EBIT ÷ (Net WC + Fixed Assets)

→

Combine the two ranks. A stock ranked #10 on cheapness and #20 on quality scores better than one ranked #1 and #400. The screen rewards being good at both.

What it deliberately ignores: the narrative, the hype, next quarter's guidance. It's a discipline for buying solid, cheap businesses in bulk, exactly what Greenblatt's book set out to do.
