Top Short Interest Movers
$ENRD was the week's most extreme story. Short interest exploded 416% in a single week to 253,000 shares. Cost to borrow hit 351% — the highest on record. Availability collapsed to 1.9%. That is a maximum squeeze-pressure setup. It arrived post-earnings.
$MAIR saw short interest surge 69% in one week to 6.6 million shares. The move coincided with analyst target cuts and a declining stock price. Bears added aggressively into the weakness.
$CGNX short interest spiked 33% in a single day to 7.29% of free float. Availability fell 65% simultaneously. The intraday speed of that build is unusual.
$EMEQ saw short interest jump 249% in one day to 6.1% of float. Cost to borrow ran to 10.4%. The move looks driven by short covering volatility rather than a directional conviction build.
On the unwind side,
$EROK short interest dropped 28% in one week to 659,000 shares. Utilization collapsed to 0.3%. Availability surged to 9,999%. Bears are exiting completely.
$MGEE covered 22% of its short book in one week. Availability at 926% means there was no friction on the exit.
