Calls Surge, Ratios Signal Rare Sentiment Shifts

Options traders showed sharp conviction across two names on Thursday, with WFRD and NTRS generating the most unusual flow of the session.

Weatherford International call options surged after the oilfield services firm reported earnings. The stock jumped 7.8%. Days to cover sit at 8.3. Barclays maintained an overweight rating, though it cut its price target to $139.

Northern Trust produced a rarer signal. Its put/call ratio hit 4.1 standard deviations above its 20-day mean. That reading points to an unusual flush of put sellers, not put buyers. When the ratio spikes this far in that direction, it typically reflects a crowded hedging unwind or a large call sweep against existing protection.

Elsewhere, short sellers rebuilt positions in the Grayscale Ethereum Staking Mini ETF (ETH). Short interest rose 199% in one week to 0.62% of float. Cost to borrow doubled to 0.79% in the same period, up from 0.39% on October 14.

The broader tape carries context worth noting. Taiwan export orders hit a September record in 2026, up 62% year on year to $114.2bn. That data sharpens the bull case in semiconductor-adjacent names where options sentiment has also stayed positive. US financials sector buybacks hit 190 million shares in Q2 2026, the largest second-quarter total in 12 years, a structural support for names like NTRS where options flow has now turned sharply bullish.
