The week of May 11–18 was defined by a single tension: earnings beats that failed to clear the bar, and a short-selling community that refused to stand down. Across 2,152 pulse signals, the dominant pattern was shorts rebuilding into or immediately after results. Options markets flashed extreme readings in both directions, with pharma and consumer names attracting the heaviest put buying. Meanwhile, the borrow market seized up repeatedly across small and micro-caps, with cost-to-borrow readings hitting historic extremes on dozens of names.
LZMH was the week's most aggressive short build. Short interest surged 446% in a single week. The stock fell 93% over the prior month, attracting fresh bearish positioning as borrow remained accessible.
SHAZ moved in the opposite direction. Short interest nearly doubled (+99%) to 847,000 shares. Utilization hit 91%. The stock rallied 68% in a month — a classic setup where shorts and bulls are in direct conflict heading into earnings.
XHLD saw shorts surge 131.6% in one week. Borrow costs sat near 29%. The stock is testing 52-week lows, suggesting fresh conviction on the downside.
CYAB offered the week's most dramatic short cover. SI dropped 57.5% in a week to 307,000 shares. Cost-to-borrow normalised after spiking above 230%, signalling the squeeze cycle is unwinding.
PN collapsed 98% in short interest in one week to just 8,288 shares — yet borrow costs stayed extreme at 809% annualised. That disconnect signals the squeeze is over but residual risk premium remains embedded in the lending market.
AIDX saw the reverse of its prior extreme. Shares borrowed plunged 48% in one week. Cost-to-borrow fell to 34% as short sellers exited en masse.
The options market threw up some of the most extreme readings in 52 weeks across the week.
CVNA hit a put/call ratio of 8.58 — the highest in a year and 4.3 standard deviations above its 20-day mean. Bears piled in at record pace.
FMX registered the week's most extreme reading. Its put/call ratio exploded to 23.89, nearly 11x the 20-day average of 2.19. ORTEX flagged it as the most extreme options sentiment in the stock's history.
GEHC saw its PCR hit 2.22, a 52-week high, as analysts slashed price targets. Extreme pessimism coincided with fresh target cuts — a convergence of two bearish signals.
TAK appeared twice in the week's options alerts. Its PCR hit 2.09–2.14, a 52-week high on both occasions. Options traders flipped sharply defensive amid pharma sector volatility.
On the bullish side, VICI saw its put/call ratio plunge to 0.36 — four sigma below its 20-day mean. Aggressive call buying dominated. HYDR saw extreme call-side positioning as the hydrogen ETF rallied 62.9% in one month.
IBP registered a PCR of 5.08 — a 52-week high — following a 29% monthly decline. Bears loaded up on downside protection even as insiders bought the crash.
Technology & Semiconductors: The chip trade dominated the week. NVDA headed into its earnings window with shorts rebuilding and China optimism lifting the stock. SOXL shorts hit a 52-week high in options hedging demand, yet the ETF continued to rally. SOXS bears were explicitly described as paying up to maintain positions against the chip rally. AMD saw its earnings pop met with a wave of analyst upgrades and short covering. NXPI rallied 44% in a month as shorts unwound.
Healthcare/Pharma: Bearish pressure was widespread. TAK, GEHC, SGMO, and LENZ all saw extreme put activity or rising short scores. APLS shorts covered on the back of a Biogen buyout reshaping the trade. The week closed with AMGN heading into Monday earnings with options flashing caution.
Airlines: AAL saw short interest hit a five-week high. Options turned defensive simultaneously — a convergence alert. DAL saw shorts build as options traders reached for cover. ALK shorts retreated but a Citi downgrade complicated the picture.
Energy: CVX and COP shorts retreated as the energy sector rallied hard. USO borrow remained fully tapped with short interest at 104% of float — a structurally extreme reading.
Consumer Discretionary: CVNA bears piled in at record pace. TJX saw bears build ahead of May 20 earnings. Leslie's saw a dramatic short squeeze as the stock doubled, with borrow costs following price higher.
The week's strongest multi-signal stories are the ones worth watching most closely.
WOLF: Short interest at 74% of float. Stock doubled. Borrow market maxed out. One of the most structurally dangerous setups of the week for bears.
QUCY: Short interest hit 46% of float. Borrow market imploded. A drone deal rally triggered the squeeze. All signals fired together.
YOOV: Short interest surged 6,421% in a single week. Borrow costs exploded. An extremely rare event in a very small name.
FCEL: Call buyers flooded the options market as shorts added positions. The stock tripled in a month. Options and short interest signals directly contradicted each other.
Ford (F): Options hit a two-year bullish extreme while shorts built and borrow tightened. A large-cap convergence alert that warrants attention.
CVNA: Put/call ratio at 52-week highs. Shorts piling in at record pace. Borrow costs following. All three signals aligned bearishly.
DXCM: Bears building ahead of May 27 earnings. Multiple signal types converging pre-event.
TJX: Bears active ahead of May 20 earnings. Options and short interest both pointing in the same direction.
