Cerebras Systems enters the back half of August with a notable tension: shorts are quietly covering, the stock has given back ground sharply, yet every analyst who filed a note this week held their Buy rating and their targets remain well above the current price.
The short-side story has shifted meaningfully from the notes filed earlier this month. Short shares fell another 8% on August 18 to roughly 11.6 million — the lowest reading in the past six weeks and a 13% reduction over the week. The one-month trend had been up 3%, but the recent daily unwinds suggest the covering that began tentatively after the August 12 earnings print is now accelerating. That said, the borrow market remains structurally tight. Availability has risen from the extreme near-zero readings of mid-August — as low as 0.17% on August 13 — to 4.9% on August 18, a notable loosening in absolute terms even if the pool is still far from generous. Borrowing costs have followed the same path, falling 28% over the week to 1.5%, their lowest level in over a month. The picture is one of constraint easing at the margins, not a full reopening of the lending market. Shorts who wanted to cover found more room to do so this week than at any point in the prior fortnight.
Options positioning remains defensive, though the extreme has passed. The put/call ratio fell to 1.18 on August 18 from the record high of 1.33 hit the prior session — the note filed yesterday flagged that 1.33 reading as the highest in CBRS's listed history. At 1.18, the PCR is still more than two standard deviations above its 20-day average of 0.79, close to the 52-week high. Demand for downside protection remains well above normal even as the most acute panic reading fades. The setup points to participants who rode the August rally still holding put protection into the September 22 earnings date rather than unwinding hedges.
The Street is uniformly constructive, and this week's analyst activity reinforced that. Rosenblatt and Needham both reiterated Buy ratings with $300 targets on August 19. UBS raised its target from $320 to $330 after the August 12 print, while Morgan Stanley also lifted its number, to $279 from $273. Citigroup was the sole dissenting move, trimming from $340 to $320 while staying at Buy. The consensus mean target is $291.64 against a current price of $220.01, implying roughly 33% upside. Bulls centre on strong revenue growth, expanding partnerships, and AI infrastructure tailwinds. Bears flag customer concentration and the sustainability of large-deal-driven beats — the June earnings print triggered an 18.8% one-day drop, a reminder of what concentrated revenue exposure can do when a quarter disappoints. The August 12 result was far gentler, down just 1.6% the next day, suggesting the bar was better calibrated.
Institutional ownership is anchored by concentrated early-stage holders. FMR added 28.7 million shares as of June 30, making it the largest reported holder at 12.1% of shares outstanding. Founder Andrew Feldman holds nearly 6% directly. On the insider side, director Steven Vassallo sold approximately $11 million of stock across multiple tranches on August 14 at prices in the $216–$220 range — effectively right where the stock closed Tuesday. The 90-day insider net is modestly positive at $14.6 million, but the Vassallo selling is the most recent and largest single cluster of supply from the inside.
The ORTEX short score has eased from 68.5 on August 7 to 65.9 on August 18, a direction consistent with the covering trend — bearish conviction is declining, not building. What to watch next is whether the short cover continues at pace or stalls as availability re-tightens around the September 22 earnings date, and whether the put/call ratio normalises back toward its 0.79 mean or remains elevated as a structural hedge on the AI infrastructure thesis.
