I am seeing ultra high IV on a select basket of stocks, Last time I saw such high 80+ implied volatility was before we had the S&P crash to 800 and under. I wonder if in the next few days you will see a mass pullout of equities and people trying to get safe. No one is going to feel comfortable having a margin balance when a stocks could post insane prints causing portfolio liquidations at the most inopportune times. I think Monday will bring a mass exodus as people will no longer trust the market process and fear a worse melt down. I say stick your 5 buck bids on stocks you want to own, you might end up getting filled.
