On correlation and hedging
Still trying to wrap my head around effective hedging with negatively correlated assets. Does anyone have a preferred method or specific metrics they track beyond just the correlation coefficient itself, particularly when looking at intra-day $SPX and $VIX moves?

It's a tricky one because that correlation isn't always stable, especially intraday. Beyond just the coefficient, I look at the realized variance and skew of the ratio between the two, as that can give a better sense of how reliable the hedge has been historically and where it might break down.
