Knight-Swift (KNX) and Schneider (SNDR) Shares Surge as Crude Plunges, Easing Fuel Costs

Shares of Knight-Swift Transportation and Schneider National soared on May 26, 2026, after WTI crude oil prices tumbled 4.7% to $92.94 a barrel, providing direct margin relief to fuel-dependent trucking and logistics firms. The drop in diesel costs, a major operational expense for carriers, is expected to boost profits across the transportation sector. Rail and air freight operators also benefited, with lower jet fuel and diesel prices improving operating margins. The rally was further fueled by easing U.S.-Iran tensions, which reduced supply-chain risks, and a decline in Treasury yields that makes fleet financing cheaper. Knight-Swift hit a 52-week high of $72.94, surging 39.7% year-to-date. The stock has experienced 12 moves of more than 5% over the past year, indicating high volatility but also the market's sensitivity to oil price swings.
