You're either LONG or your SHORT.....if you're SHORT, you're only in it to sell it which means you need the LONG's to drive it up and you need the LONG's to panic (which is what they're doing) so they'll sell it. This is what Babawhatever and his weeeeeeeee live by.
So, if you're LONG do what Warren does and select the stock because it makes sense to you and then let it go.....quit watching the stock daily....or as some of you do, several times a day.....keep it for a year and check it out quarterly....if it made sense to you a year ago then it will make sense to you a year from now....GLTA and keep buying if it makes sense to you!
