As a CFA charterholder (who thinks CFA is worth little), please shut the f* up.
<i>I'm a whiny, jealous type who does not like to promote the integrity and competence or strive to improve the integrity and competence of CFA charterholders and candidates.</i>

you must be selling the teenies and those 5% losers must be whoppers. or maybe you're not profitable 95% of the time.
Quote from atticus:
You can't apply delta1 backtesting to products with many orders of convexity. Px & vol; delta, gamma, theta, vega, rho; vanna, vomma, charm... the modality of delta alone would be a bitch.
Knowing what is absurdly obvious to everyone here; why not simply backtest the underlying?
The rationale for trading vol is the convexity. Coincidentally, it's also the reason that you don't backtest vol.
