The week of August 17 was defined by extreme short-side stress in small caps. ENRD saw the most violent move — short interest exploded 416% in a single week as borrow costs hit an all-time record. Elsewhere, MAIR shorts surged 69% amid analyst target cuts, and convergence signals fired across more than two dozen names from regional banks to defence.
ENRD was the week's standout. Short interest jumped 416% to 253,000 shares. Cost to borrow hit 351% — the highest on record. Availability collapsed to 1.9%. That is maximum squeeze pressure, triggered post-earnings.
MAIR saw short interest climb 69% in one week to 6.6 million shares. Analyst target cuts and a declining share price drove the build. Severity: critical.
EMEQ added 249% in a single day, reaching 6.1% of free float. Borrow costs sat at 10.4%. The move reflected rapid short-covering volatility rather than a clean directional bet.
CGNX short interest rose 33% in one day to 7.29% of free float — the highest spike in weeks. Availability dropped 65% alongside the build, signalling tightening borrow conditions.
CMI added 18.9% in a single day to reach 2.22% of free float. The move came amid broader sector weakness.
EROK moved the other way. Short interest fell 28% to 659,000 shares as utilization collapsed to 0.3%. Availability surged to 9,999%, suggesting near-total short capitulation.
MGEE short interest dropped 22% to 3.79% of free float. Abundant borrow availability at 926% enabled easy covering.
This week's pulse data covered a broad, undifferentiated universe — sector tagging was largely unresolved. That said, several clear clusters emerged from the mover and convergence data.
Regional banking saw aligned short-side activity. HTB short interest rose 20.6% to 2.02% of free float. BNY options sentiment turned bearish as shorts quietly built. PNC saw call buyers push back against rising short bets.
Defence and industrials also drew attention. BWXT options hedging hit a 52-week high. RTX options pessimism peaked even as analysts raised targets. CMI saw a sharp one-day short spike.
ETF shorts were active too. PTF — the Dorsey Wright momentum ETF — saw short interest rise 28% to 1.38% of free float. Borrow availability fell sharply to 58%.
Multiple names fired cross-signal convergences this week, with short interest, options, and borrow data aligning.
ENRD appeared in both the top movers and convergence tables. Shorts rebuilt fast after earnings. Borrow remained punishing at 351% CTB.
UAMY saw calls rising as shorts added into a locked borrow market — a classic squeeze-setup signal. Borrow was effectively unavailable.
ALOY flagged with an empty borrow pool ahead of earnings. No shares available to borrow with a catalyst imminent.
WYFI borrow cost tripled in two days as the lending pool drained — a rapid deterioration in short-side access.
DOCN short unwind deepened while options skew stayed extreme — divergence between positioning and derivatives sentiment.
URGN moved bullishly: analysts raised targets, shorts covered, and calls surged in concert.
WB — Citi cut to Neutral as the borrow market hit breaking point. Both fundamental and technical short pressure aligned.
Bunge borrow costs tripled as put demand climbed. A rare cross-asset short signal in the agriculture space.
TJX drew a Citi downgrade to Neutral after an earnings miss. Options shifted defensively in tandem.
MCK options signalled caution as shorts rebuilt post-earnings — a pattern seen across several reporting names this week.
