Why GuruScreener

Serious investing, minus the busywork.

01

Proven, not invented

Every screen is a published strategy with a real track record: Greenblatt's Magic Formula, Graham's net-nets, O'Neil's CANSLIM. You're not guessing; you're standing on decades of evidence.

02

No spreadsheets, ever

ROE, P/E, ROIC, earnings yield, debt ratios, computed for every US stock and refreshed daily. What used to be a weekend lost in Excel is now a single dropdown.

03

Conviction to hold

Every ranking comes with the why: the metrics, the thesis, the backtest. Understand a pick well enough to hold it through a rocky quarter instead of panic-selling.

From the community

Built for patient, self-taught investors.

I stopped doom-scrolling stock tips. Now I run the Magic Formula screen once a month and actually sleep at night.

The backtests are what sold me. I can see a strategy worked for years before I risk a single cent of my own.

Finally a screener that explains why a stock ranks. I've learned more in a month here than in a year of YouTube.
