The picks should be looked at, just as any stock you are going to buy:
1.quick flip ?
2.hold for a few days to let news get around?
3.trade it over a few weeks?
4.buy, and hold for a few months?
5.buy, and hold longer-term?
Choi cannot possibly give counsel to each person who buys a selection that he has made. Many people just "lurk" here, never contribute, and just want info. Others need to be told to do everything for any number of reasons (lack of experience, lack of knowledge, chronically trading with scared money), others are able to make decisions about ANY stock because they know themselves, and know what they are here for, and are able to navigate in this jungle with grace, and strength. You cannot know the person who picks the stocks, you cannot know the everything about a company, but you can endeavor to know yourself, and that is where your advantage comes. :)
