Quote from sle:
Should there be a protracted period of highly correlated movement (also known as a market crash), you will lose money on both short vol position and on your stat arb strategies. Just saying that being a provider of liquidity and being short convexity does not go as well together as you make it sound.
This response is more to the point.
You make an assumption that I'm net long stocks...
And hedging that with short Vol.
No, I'm very diversified market neutral stocks...
And hedging that with short Vol...
Plus I'm scalping Vol all day long...
Though not so much the last 10 days near all-time lows.
I've traded through 6-7 "market crashes"...
The first one being the Russian default in 1998.
My Portfolio has held up in each "crash" since 1998...
And then you enter a period of panic and wider spreads...
I throw off money for weeks or months after a "crash".
So I take a 3% hit on the short Vol and get out...
Then start grinding 1%/week until the market panic subsides.
By shorting Vol in the form of VXX hedges...
I'm gaining a stream of income is dead markets...
In return for maybe a 3% hit in a spike like August 2011...
With the spike followed by windfall market making profits.
I'm actually hoping for Apocalypse in spite of being short Vol.
