I had read on this forum at some time that you can short QQQs on a downtick, but I have also recently heard that the uptick rule applies to them and you cannot short them on a downtick. Since I have heard different things, can anyone help straighten me out on what shorting rules apply to QQQ? I know they trade on both amex and nyse. I am also unclear on whether the uptick rule is a nasdaq rule or whether it is an SEC rule that applies also to nyse and amex as well as nasdaq. Does it apply to amex? Does it apply to QQQs? Related question, if the rule does apply can I get around it if I hit a bid 1 or 2 cents off the inside bid when shorting? Thanks in advance for your help.
