Ha... Late night cooking for the week is dangerous...
Yeah, if you hold a weekly overnight, you'll see 20% in premium loss easily if you go out of the money... I generally only like to intraday trade weeklies and am looking forward to my cash account.
Friday is fun since that is the rare time there is no premimum on quality plays. I watched SINA puts go from 7 cents to 40 cents last Friday... You can pick up something like AMZN 2 or 3 bucks below a strike price for nothing and get a run for 2 or 3 dollars in the money for 1000% gainers. There's usually one every Friday! But that should be reserved to gambling money as they will get wiped out if it doesn't work.
