LPTH Surges 22% as Shorts Hold Firm Above 20% of Float

LightPath Technologies ripped 22% higher on Tuesday, yet short interest has barely budged — a classic standoff between a stock that just moved hard and a short book large enough to signal the bears aren't ready to capitulate.

The tension in positioning is real. Short interest climbed to 20.5% of the free float as of July 21 — up 6% on the week and 28% over the past month, continuing the build that was already underway when the previous note flagged the near-doubling from June levels. That is a genuinely heavy position for a small-cap optics name. Yet the borrow market is telling a different story: cost to borrow remains near 0.45%, among its lowest readings of the past 30 days, and availability is running at 152% — meaning there are still roughly 1.5 shares available to lend for every share already borrowed. Shorts are adding conviction, not scrambling to cover, and there is plenty of room in the lending pool for more to pile in if they choose. One wrinkle: availability has tightened noticeably from the 195–200% range seen in early July, so the borrow market is getting incrementally busier even if it remains far from stressed. Options sentiment flipped more bullish this week. The put/call ratio dropped to 0.58, now nearly a full standard deviation below its 20-day average of 0.64 — call buyers stepped up into the rally, rotating away from the more defensive posture that had persisted through most of June and early July.

The Street is uniformly bullish, though the most recent analyst action is now over two months old. Canaccord Genuity raised its target to $16.50 in May after maintaining a Buy rating, and that consensus mean of roughly $16 implies about 26% upside from Tuesday's $12.66 close — tighter than the 54% gap that existed before the rally, but still positive. The bull case rests on the $100M-plus backlog, growing defense and security demand, and the BlackDiamond infrared material gaining share against traditional germanium. Bears point to negative ROCE, an EV/EBITDA that remains deeply negative, and the risk of customer concentration. The ORTEX short score has crept up to 64.7 — its highest reading in recent months — driven almost entirely by a sharp jump in forward EPS estimates rather than quality or balance-sheet improvement.

The institutional ownership picture adds context. North Run Capital, the 10% owner and board-represented fund, sold roughly 3.6 million shares at $14 in early June and had been steadily trimming since March. That selling explains part of the weight on the stock through the spring and early summer. North Run now holds just under 2.9 million shares — still a meaningful stake, but well down from its earlier level. More recently, Tema ETFs built a near-2-million-share position as of June 30, and BlackRock added over 1.4 million shares in the same period. That emerging institutional appetite from passive and ETF buyers is worth watching alongside the continued North Run overhang.

Earnings history adds one more complication. The last two prints produced immediate declines of 5% and 10.5% respectively on the day, though the May quarter recovered strongly over the subsequent five trading sessions. The next report is scheduled for September 17 — still almost two months away, but the pattern of day-one weakness followed by a multi-day reversal is worth keeping in mind as the stock enters that window with a freshly rebuilt short book and a price level that has bounced sharply from its lows.

What to watch: whether short interest continues to climb past 20.5% of float despite the rally — further accumulation at these prices would tell a more committed bear story — and whether availability continues its tightening trend toward the tighter end of the recent range.
