Balance statistical prudence with operational realism,
focusing on configurations that remain stable across perturbations rather than those that shine under a single historical backtest.
💣Problem of Sharpe:
(1) its assumption of a normal distribution for PnL returns
(2) it being a point estimate instead of a range
(3) less reliable for non-linear risk-return relationships
(4) penalises even desirable volatility
(5) difficult to compare across different timeframe
High alpha means nothing if it is not consistent;
low beta means little without meaningful signal;
and IR is the sanity check that ties both together.
