Cerebras Systems looked like it was catching a break. Borrow availability had recovered to roughly 11.5% earlier this week. Now that relief has reversed sharply — availability has collapsed back to 5.4%, down 42% in a single week.
Yesterday's article noted that CBRS had pulled back from the extreme borrow tightness seen through late June and early July, when availability sat at zero across multiple consecutive sessions. That easing has unwound fast.
Availability now stands at just 5.4%. For every 20 shares already borrowed by short sellers, fewer than one remains in the lending pool. That puts the borrow market back in deeply constrained territory — well below the 50% threshold that signals a genuinely tight market.
Short interest itself is rising in parallel. Shares short hit 12.3 million as of July 22, up 10.8% in one week and up 28.2% over the past month. That sustained build — not a one-day spike — is what's driving the tighter borrow conditions.
The put/call ratio eased to 0.72 on July 22, down from the 0.81 spike recorded the day prior. The prior article flagged that 0.81 reading as more than two standard deviations above the 20-day mean. At 0.72, it sits roughly one standard deviation above — still above the 20-day mean of 0.64, but no longer at alarm levels.
The 52-week peak for the PCR stands at 0.92. Current positioning remains in the upper half of the year's range, suggesting options traders have not fully unwound their hedges despite the stock's continued rally.
The bear case in the lending market sits alongside a firmly constructive analyst community. Consensus is rated Buy. UBS raised its target to $320 on June 24. Morgan Stanley moved to $273 from $250. The mean price target across analysts sits at $291 — roughly 39% above the current price of $209.80.
That gap between where analysts see fair value and where short sellers are pressing is worth watching. The ORTEX short score stands at 67.8, creeping higher across the past week but not yet at an extreme.
The key question is whether availability continues to fall toward zero — the level seen repeatedly through June. If short interest keeps building while the lending pool stays constrained, the cost to borrow (currently 1.88%, down from above 4% in late June) could re-accelerate. Next earnings are scheduled for September 22.
