There was that time I "invested" in an inverse VIX ETF. It was doing great until the day the VIX spiked and it got liquidated.
Funny enough after the liquidation I had about as much money left over as I put in originally. So I didn't lose much skin and got a great story to tell.
"Yes, the VIX is overpriced. Although you can't make a living by shorting it. Both statements are true at the same time."
