Bullish call positioning defined the week of September 21. Extreme low put-call ratios hit several names across autos, utilities, and financials. Yet bearish hedging surged in equal measure elsewhere — earnings-linked put buying and sector-level stress signals kept the week far from one-directional.
ASH — PCR 0.134, –4.3 SD Ashland's put-call ratio collapsed to 0.134 on Monday. That is 4.3 standard deviations below the 20-day mean of 0.348. Calls overwhelmed puts by roughly 7-to-1. No upcoming earnings catalyst was cited — the positioning looks purely directional.
DRVN — PCR 0.0047, –4.3 SD, 52-week low Driven Brands printed the most extreme bullish read of the week. Its ratio hit 0.0047 — a 52-week low and 4.3 standard deviations beneath the 20-day mean of 0.0082. At near-zero, virtually no put volume registered. That level of call dominance is statistically rare.
HYLN — PCR 0.1397, –4.0 SD Hyliion's ratio fell to 0.1397 against a 20-day mean of 0.163. The stock gained 15.6% in the prior week. Options traders chased the rally with calls rather than hedging gains with puts.
— PCR 3.39, +4.2 SD, 52-week high MillerKnoll flipped to the opposite extreme. Its put-call ratio hit 3.39 — the highest in 52 weeks and 4.2 standard deviations above the 20-day mean of 1.16. Earnings were the stated trigger. Traders loaded puts ahead of the release, signalling heavy downside concern.
WLDN — PCR 1.49, +4.35 SD, 52-week high Willdan Group saw its ratio spike to 1.49. That is a 4.35 standard deviation move above the 20-day mean of 0.50 — the largest z-score breach of the week on the bearish side. The 52-week high reading suggests positioning not seen in at least a year.
PB — PCR 0.49, nearly +5.0 SD Prosperity Bancshares produced the most statistically significant bearish read in the financials space. The ratio hit 0.49, nearly five standard deviations above its 20-day mean. The regional banking sector remained under broad pressure this week.
IRDM — PCR 0.6208, 52-week high Iridium Communications hit a 52-week high put-call ratio of 0.6208 ahead of Thursday earnings. Traders positioned firmly for downside protection. Elevated pre-earnings PCR at an annual extreme is a clear signal of market anxiety around the release.
PRK — PCR 1.17, +4.1 SD, 52-week high Park National's ratio exploded to 1.17 from a 20-day average of just 0.16. That 7x jump pushed the reading 4.1 standard deviations above the mean. The move to a 52-week high signals unusual hedging demand for a stock that rarely sees heavy options activity.
SNX — PCR 0.4432, +4.3 SD, 52-week high TD SYNNEX hit its highest put-call ratio in 52 weeks ahead of earnings. The 4.3 standard deviation spike above the 20-day mean mirrors the pattern seen in MLKN and IRDM. Earnings-linked defensive positioning was a clear theme late in the week.
EWBC — PCR 0.41, –4.0 SD East West Bancorp moved the opposite direction. Traders dropped put exposure ahead of October 20 earnings, pushing the ratio 4 standard deviations below the 20-day mean. The stock rose 0.67% on September 21. The low PCR suggests the options market is positioned constructively into results.
Earnings-driven hedging Pre-earnings put buying dominated mid-to-late week. MLKN, IRDM, and SNX all printed 52-week high put-call ratios in the days before their releases. This is a textbook pattern — uncertainty compresses as the event approaches, but options markets can show extreme skew when consensus lacks conviction.
Regional banks under pressure PB and PRK both registered extreme bearish options readings this week. Prosperity Bancshares came closest to a five-sigma event. Park National's ratio jumped from a base of 0.16 to 1.17. Regional bank sector stress, already a recurring theme in 2026, drove unusual hedging demand across smaller names.
Materials and industrials — split sentiment VAW — the Vanguard Materials ETF — hit a 52-week high PCR of 2.22, up 4.1 standard deviations from its 20-day mean. That signals broad-based sector hedging demand in materials. On the industrial side, WOR moved the opposite way post-earnings, with its ratio jumping to 0.2553 but on bullish call flow. HII — down 7.4% over the prior month — saw its PCR reach a 4-standard-deviation high of 1.034. Defense names with recent price weakness attracted put interest.
Bullish outliers across small-caps Several smaller names registered extreme call dominance without obvious news catalysts. HNGE hit a 52-week low PCR of 0.28, with bulls outnumbering bears 3.6-to-1. GRC fell to 0.18 — also a 52-week low — at –4.3 standard deviations. These moves may reflect speculative call buying rather than informed positioning, given the absence of near-term catalysts.
