Why this matters — Three distinct ORTEX short-interest indicators spiked simultaneously on PMEC on April 23, signaling an acute shortage of shares available to short. The convergence of cost-to-borrow, utilization, and short interest increases points to a tightening borrow environment for this micro-cap environmental services stock.
Cost to borrow rocketed 5,706% in one week. PMEC's CTB jumped from 2.47% on April 16 to 143.36% on April 23. The annualized rate now exceeds 143%, making new short positions extremely expensive to maintain. This is one of the sharpest weekly CTB spikes ORTEX has recorded for any stock this year.
Short interest surged 319% in a single day. Shares short climbed from 54,394 on April 22 to 227,662 on April 23. That represents 0.59% of the free float. The jump was the fastest daily percentage increase since ORTEX began tracking the name, though absolute short interest remains modest in share terms.
Utilization hit 94.2%, approaching the 52-week high of 100%. Nearly all available borrow inventory has been lent out. Utilization sat below 2% as recently as April 22, then vaulted to 94.2% the following session. The stock previously touched similar levels on March 19 (62.5%) and March 17 (55.0%).
ORTEX's short score climbed to 66.8 on April 23, up from 28.3 the prior day. The composite metric ranks PMEC's short-squeeze risk in the 67th percentile relative to other names. No analyst, institutional, or insider data is available for this thinly covered stock.
