Magnolia Oil & Gas (NYSE: MGY) was cited as the preferred stock among three companies trading near 52-week highs, while Sensata Technologies (NYSE: ST) and Tennant (NYSE: TNC) were flagged as riskier names, according to a May 14, 2026, StockStory report. Magnolia, an oil and gas producer focused on South Texas, was trading at $27.80, or 9.8 times forward earnings, despite a one-month decline of 6.4%. Sensata, a supplier of analog sensors for industrial and transportation markets, rose 15.2% over the past month and traded at $44.93, or 11.7 times forward earnings. Tennant, which makes cleaning equipment and autonomous mobile robots, gained 9.7% over the past month and traded at $87.12, implying a 15.2 times forward price-to-earnings ratio.
