Choppy Waters, Visualized

The 30-minute chart of the QQQ, ETF for the Nasdaq's top 100 stocks, below, illustrates the whipsaws over the last week or two. 

At the moment, bulls are trying to defend the lower end of this rocky range. $108.61 looks to be a significance level below, now, defended twice late this week, including within the last hour. 

Leaders like FB GOOGL NFLX are lagging here, with FB the notable weak link today. 

Still, bears have yet to cement any type of meaningful downside reversal in the broad market off the February rally, which means tactical rangebound strategy is still likely correct.
