Growth stocks, as represented by the Russell 2000 Growth Index, have generally outperformed value stocks since mid-2010 (see the chart below, denoted by the green boxes). Since the start of 2016, however, value has outperformed growth, as can be seen by the large red box on the right side of the chart.
A 50-day exponential moving average is employed to demonstrate the price activity in favor of one versus the other. What is interesting on the chart is the top portion, which shows the RSI of the Growth/Value stock ratio. That RSI was deeply oversold and has crossed above the 30 level, a bullish development. This may be an indication of a shift in sentiment back toward growth stocks.
