🔬 Verification Methodology
12 articlesWhat a Base Rate Is — Why "a 70% Hit Rate" Is a Meaningless Number
Why you can't just look at a hit rate. A base rate is the rate at which something happens anyway, independent of any signal. We use DawnScan's real measured data to explain the trap of a hit rate published without a baseline.
The Volatility Illusion — Not a Good Signal, Just a Stock That Whipsaws
High-volatility stocks hit a target price often, independent of any signal. Real measured base rates by volatility quartile ranged from 4.0% to 51.7%. Why stratified verification is necessary.
If the Same Stock Keeps Getting Scanned, Is That a Good Signal? — No Evidence It Is
When the same stock triggers a signal multiple times, it looks like a stronger signal. Real measurement showed the hit rate was actually lower, though overlapping confidence intervals leave it unconfirmed. What repeat triggers mean, and the duplicate-observation problem.
Survivorship Bias — Drop the Failures and Performance Improves on Its Own
Drop delisted and trading-halted stocks from the sample and performance looks better than reality. We explain how survivorship bias distorts backtests and hit-rate statistics, and how to prevent it.
The Trap in a Hit Rate's Denominator — In-Progress Stocks Inflate the Win Rate
Counting only the winners among stocks whose outcome isn't decided yet structurally inflates a hit rate. We explain immortal time bias and publish, with the real numbers, how DawnScan actually corrected its own hit rate from 39.8% to 30.7%.
Multiple Testing — Run 30 Indicators and One Wins by Chance
Test several indicators at once and something that looks significant purely by chance is bound to show up. We explain the multiple-testing problem and why a BH (FDR) correction is necessary, using a real verification case.
Lift and Confidence Intervals — How to Tell If a Signal Is Real
Lift shows how much better a signal is than the base rate; a confidence interval shows how much you can trust that number. We explain, with no formulas, why you shouldn't trust a high hit rate from a small sample.
Backtest Overfitting — Why a Perfect Past Strategy Falls Apart
Why a strategy with a dazzling historical return falls apart in live trading. We cover the structure of overfitting, the difference between in-sample and out-of-sample data, and why forward testing is necessary.
