Fundamental backtesting,
finally possible with your screens.
Build a screen the way you do on Screener.in — then replay it across a decade of point-in-time data and see exactly what holding those rules would have returned.

Why this is different
A screener is a snapshot.
A backtest is the whole movie.
Screener.in tells you which stocks pass your filters today. It can't tell you whether holding those rules would have actually made money. We replay your screen across history — buying and selling on each rebalance using only the data that existed at the time.
Preset strategies
Start from a tested idea, or build your own.
Four classic fundamental screens, already backtested on Nifty 500. Click any one to load it into the builder up top.
How it works
From idea to evidence in three steps.
Build a screen
Pick fundamental rules — ROE, debt, growth, valuation. Same mental model as Screener.in, no code.
Replay it through time
We rebalance on each historical date using only data filed by then. No look-ahead, no survivorship bias.
Read the evidence
Equity curve, CAGR, drawdown and Sharpe — benchmarked against the Nifty 50 so you see real outperformance.
Methodology
Auditable by design.
A backtest is only as trustworthy as its data discipline. Here's what we hold ourselves to — and surface to you on every run.
Read the full methodology →Point-in-time data
Every metric is anchored to its filing date. On 14 Mar 2018 the engine sees only what was public on 14 Mar 2018.
No survivorship bias
Delisted and merged companies stay in the universe for the dates they existed. Winners aren't cherry-picked in hindsight.
Realistic costs
0.30% transaction cost applied per leg on every rebalance — entry and exit — so returns aren't frictionless fiction.
Honest gaps
When a quarter is missing or a ratio can't be computed point-in-time, we flag it instead of silently filling it in.
