Falling crude prices are boosting the airline sector this morning, Delta Air Lines Inc (NYSE:DAL) last seen up 2.9% at $84.59. The equity remains within a chip-shot of its June 15 record peak of $87.39, up 21% for 2026 thanks to an added layer of support at the 20-day moving average.
Options traders were extremely call heavy ahead of the crude-induced surge. At the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX), Delta Air Lines stock's 10-day call/put volume ratio of 2.15 ranks in the 70th annual percentile.
This sentiment is echoed by the stock's Schaeffer's put/call open interest ratio (SOIR) of 1.16, which ranks higher than 89% of readings from the past year. Should these bullish bets begin to unwind, it could trigger headwinds for the airline outperformer.
Short sellers have been retreating, with short interest down 4.9% during the most recent reporting period. This accounts for nearly 4% of the stock's available float, or over two days' worth of pent-up buying power.
It's also worth noting that the stock sports a Schaeffer's Volatility Scorecard (SVS) of 12 out of 100. This suggests the equity has consistently realized lower-than-expected volatility over the past 12 months -- a boon to premium sellers.
