Oil stocks across the board are flying higher today thanks to the sharp reversal in oil prices, but small-cap stocks are shining the brightest, with Centennial Resource Development (NASDAQ: CDEV) and Core Laboratories (NYSE: CLB) leading from the front. The double-digit price tumble in shares of Centennial Resource and Core Labs last week has presented investors in oil and gas stocks with the perfect opportunity to scoop up some shares today. Crude oil prices are reversing today after a week-long decline and are up more than 5% this morning.
