Quote from Steve Tvardek:
Remember to account for the occasional news story that wasnt planned for when the stock gaps against you 5 or so points when you'll take a 10k, 20k or ever 30k loss. Thats the risk of overnights.
Unlikely.
The price actions I do trade never gaps down because there will never be a <b>reason for them</b> to.
Holding biotech will be a different story though.
If Taking a black swan $30k lost in one day happens,
it will not effect my capital because it will be made back and a shit bag will be fedexed to the companys office.
