RSI Breaks 70 for QQQQ
With 14-day RSI moving above 70 this week, the Nasdaq 100 ETF (QQQQ) became the first major-index ETF with an overbought reading. RSI is considered overbought when above 70 and oversold when below 30. For the Russell 2000 ETF (IWM), S&P 500 ETF (SPY) and Dow Industrials ETF (DIA), 14-day RSI has yet to breach this level.
