What law is that???? 10 bucks or 5 bucks ? that makes no sense. Sure SOME funds have it in their rules that they cannot hold stocks that dont pay a dividend or are below 5 bucks but its a guideline, not a law by anyone or anything like that. In general, if the stock is below 5 for x period of time (as defined in thier investment objectives), they will liquidate. Just cause it hits 5 does not mean immediate panic - otherwise the SMARTEST short in the world would be at 5.00 or 4.99 for the easy money.
