But if a stsock is running up you have all the johnny-come-latelys plus the shorts who have to cover. Should be just as easy to run a price up as down.
plus, if you have marginable securities, you can use 1/2 the buy power they generate to buy non-marginables. Ask your broker.
You are severely misinformed. Just because you can't short a stock below $5 doesn't mean it can't be done. In fact, even etrade allows you to short $3 stocks.
The rest of your post is completely unintelligible.
