The Dow Jones Industrial Average eked out another all-time-high on Friday — its 11th record close in a row.
The S&P 500 also notched a new high and its longest winning streak in nearly a year.
But not all areas of the market are participating. Energy, the worst performing sector in the S&P this year, is down nearly 7 percent.
Using hedge fund analytics tool Kensho, CNBC looked for the most statistically oversold stocks in the energy sector, as measured by the stock's standard deviation.
Standard deviation is a measure of how spread out a data set is from its mean. In this exercise, the mean is defined as the stock's 50-day moving average.
