From that statistical standpoint, the most oversold Energy stocks are Range Resources, Anadarko Petroleum, Newfield Exploration and Chesapeake Energy.
Kensho points out the most statistically oversold stocks — which also are most likely to see near-term gains.
Take Range Resources, which as of Friday was 3.27 standard deviations below its mean.
To put it into context, 99.7 percent of values along a normally distributed set falls within 3 standard deviations, so a number greater than 3 puts Range Resources in extremely rare trading territory.
Further, Kensho notes that the past seven times Range Resources has had a drop of this magnitude, the next move is at least half a standard deviation higher.
