In trading on Thursday, shares of the GUNR ETF (Symbol: GUNR) entered into oversold territory, changing hands as low as $30.81 per share. We define oversold territory using the Relative Strength Index, or RSI, which is a technical analysis indicator used to measure momentum on a scale of zero to 100. A stock is considered to be oversold if the RSI reading falls below 30.

A bullish investor could look at GUNR's 27.4 reading as a sign that the recent heavy selling is in the process of exhausting itself, and begin to look for entry point opportunities on the buy side.
