You have to believe in a company and product..and yes...common sense plays into it.
I have a very good friend who is a multi-millionaire day trader....and as he said "If you try to gauge the stock market on a week to week...day to day basis....there is NO REASONING for how some stocks jump up and down....you have to wait atleast 6 months to really know where the stock is going....especially if you have preliminary news"---he's a PHD from yale, went to harvard and UCLA..
