The Nasdaq 100 Trust shares (QQQQ) has been doing pretty well since July of last year but the question is, will this trend continue? That's an interesting question because I really don't know. From the candlestick chart it looks like it might if it can clear the $47.92 level.
Either way, the QQQQ's is a very volatile ETF as seen on my daily volatility chart. I drew in the one, two, and three standard deviations for it and the last 3 STDEV move was this past February (2/27/2007). If I applied my S&P500 timing rules to the QQQQ's then then 2/27/2007 was a prime buying day.
Still though, the QQQQ's usually see 2 STDEV volatility moves more often than not. If I were a daytrader, I'd be trading this market!
