Small cap stocks are showing signs of being in oversold territory after a more than three-week selloff, according to Bloomberg data.

More than 15% of the S&P 600 Smallcap Index began the week trading in oversold territory, with the 14-day relative strength index below 30, meanwhile, only 3% of the index was in overbought territory. 

There have only been 66 days where the gap between oversold and overbought stocks was this wide since 2012, Bloomberg said.
