The week in one paragraph. The week of May 4–11 was defined by earnings. Over 1,200 signals fired across the ORTEX platform. Short sellers sprinted to cover on beats and dug in harder on misses. Borrow markets seized across dozens of small and micro-cap names. Options markets flashed extreme readings in both directions — from record put/call ratios to unprecedented call-buying frenzies — as traders jockeyed ahead of results.
The most dramatic short covering happened in POM. Short interest fell 50.6% in a single week to just 0.33% of float. The stock surged 39.8%. Cost to borrow retreated 19% to 59% — still elevated, but the squeeze dynamic is unwinding.
SMTK went the other way. Short interest exploded 368% in one week to 9.5% of float. Utilization jumped to 82%. The stock rallied 70% — a textbook setup for a squeeze. Traders are watching this closely heading into next week's earnings.
EDSA saw shorts plummet 52% in one week to 2.4% of float. The move followed the company's May 8 earnings report. CEO buying adds another layer to this story.
BQ short interest plunged 37.5% over the week to 1.87% of float. Shares short fell from a month-ago peak near 365,000 to just 65,543 — a sharp, sustained unwind.
CISO moved in the opposite direction. Short interest surged 253% in one week to 0.78% of float. A 65% single-day jump on May 7 drove most of that. Earnings loom.
SSM posted one of the starkest reversals. Short interest surged 3,150% over the week to 3.1% of float — then fell 21% in a single day as shorts took profits. The stock lost a quarter of its value in the period.
Analyst activity this week was dominated by post-earnings target revisions across hundreds of names.
AMD attracted a wave of target upgrades after a 63% monthly surge. The Street is chasing the rally. MCHP earned upgrades after earnings beat expectations. ON Semiconductor surged 65% in a month as analysts lifted targets across the board.
On the downside, SHOP saw targets cut after a 16% post-earnings slide. HubSpot triggered a wave of analyst cuts after its earnings collapse. Goldman Sachs downgraded EPAM as earnings relief turned to re-rating risk. Prudential drew a cluster of downgrades. Fiserv dropped 9% after Q1 earnings and analysts slashed targets.
Howmet Aerospace was one of the clearest analyst success stories. Analysts raced to raise targets after a strong print. JFrog surged 41% on an earnings beat and the Street lifted targets in unison.
Options markets were exceptionally active. The most extreme reading came from CHT. Its put/call ratio hit 52.0 on May 6 — a record high with a z-score of 4.36. The 20-day mean is 2.6. That is an extraordinary divergence and signals deep bearish conviction in options markets.
PRA saw its put/call ratio explode to 34.02 — the highest on record — ahead of May 12 earnings. Pure fear trade.
LEA posted a put/call ratio of 1.195, the highest in 52 weeks. This automotive supplier also saw short interest surge 30% over the month. Both signals point the same direction: bearish.
TNDM hit a 52-week high PCR of 1.41, then again at 1.17 the next day. Options traders are pricing in pain ahead of May earnings.
On the bullish side, BLMN saw its put/call ratio surge to 0.69 after a 41% single-day earnings pop. That reflects hedging demand — traders protecting gains, not betting on collapse.
KW put/call ratio crashed to 0.027 — a record low — as call buyers dominated ahead of earnings May 8. Extreme bullish positioning.
IFRX put/call ratio surged to 0.1546, 4.3 standard deviations above its 20-day mean, as the stock rallied 28% in the week. Both short covering and call buying aligned here.
IYE — the energy ETF — saw its put/call ratio spike to 1.56, 4.3 standard deviations above the 20-day mean, during a 4% single-day drop. Energy sector pessimism is building in options markets.
With all 1,208 pulses classified under a broad universe this week, the data reveals clear thematic clusters.
Semiconductors squeezed hard. SOXX bears retreated as the semis ETF staged a 10% weekly surge. Borrow availability on SOXX collapsed in tandem. AMD, ON Semiconductor, SWKS, and MCHP all saw short interest ease materially post-earnings. The sector-wide short squeeze dynamic was the dominant theme across chip names.
Utilities tightened. XLU borrow markets neared capacity as short sellers built a defensive stack. The convergence alert on XLU fired independently of earnings. This looks like macro hedging — not a stock-specific story.
Energy bears dug in. IYE put/call spikes, USO borrow hitting maximum tightness, and IEP positioning all point to a sector under renewed short pressure. Crude oil borrow costs collapsed at the same time — bears are repositioning, not exiting.
Small-cap biotech borrow markets seized. JAGX, CLRB, WOLF, HCAI, and ONEG all hit extreme borrow stress this week. WOLF stood out: 62% of float short as the stock doubled. That is a historically dangerous configuration for short sellers.
Fintech and SaaS saw diverging signals. Marqeta dropped 7.7% on an earnings miss — its put/call ratio hit a 52-week high. Toast gapped down 15% after a Q1 miss. Upwork was hammered after earnings. Meanwhile, JFrog and AvePoint surged on beats, attracting bullish options flow.
Several names fired multiple simultaneous signals this week, flagging the most contested situations in the market.
WOLF is the standout. 62% of float is short. The stock doubled. That is a classic trapped-short scenario — and it fired a critical convergence alert.
MNDR went from zero short interest to 152% of float — a figure that implies significant synthetic short exposure — in under ten days. Convergence alert fired.
EZGO borrow cost exploded 1,083% as short interest quadrupled. This is maximum borrow stress combined with a rapidly growing short position. Dangerous for latecoming shorts.
AMC borrow market tightened as short interest hit 17.75% of float. The convergence alert fired after the company's earnings beat landed against a fully tapped borrow market. Options traders and short sellers are directly opposed here.
AIOS borrow hit a 52-week extreme ahead of earnings. Multiple signals aligned simultaneously — this is the type of setup where unexpected catalysts can cause violent moves.
SOXX shorts were squeezed as lending availability collapsed. A sector-level convergence: broad short covering met a shrinking pool of shares to borrow.
BLZE borrow market exploded after a 71% earnings pop. Post-print short squeeze dynamics are live.
PN (Skycorp Solar) borrow cost hit 847%. Convergence alert fired. The cost alone makes maintaining this short position economically brutal.
Several names carry active signals or unresolved convergences into the coming week:
