True but the good thing in trading the NDX is that tracking the top 10 weighted stocks for that is relatively straightforward (compared to the SPY or IWM).
What does it matter? Traders TRADE price, and at the end of the day the NDX has been rallying . . . QQQQ +20% since March lows, but you haven't made a dime in the market cause you can't pull the "trigger" . . . I bet you also suffer from Erectile Dysfunction too, eh? Try taking the "Little Blue Pill" and get some BALLS for a change!
