Commvault Systems heads into its July 28 earnings window with shorts rebuilding sharply and the options market running unusually bullish — a combination that sets up an interesting tension ahead of the next print.
The positioning story is the most notable element right now. Short interest has climbed 36% over the past month, reaching 7% of free float — a meaningful step-up for a stock that was sitting closer to 5% in mid-May. The rebuild has been consistent, adding roughly 200,000 shares week after week through June. Yet the lending market tells a different story: availability is wide open, with shares-available-to-borrow running at 1,453% of current short interest — meaning there are roughly 14 shares in the lending pool for every one already borrowed. Borrow cost is negligible at 0.50%, barely changed over the month. This is not a squeeze setup. The rising short interest reflects growing bearish conviction, but conditions remain entirely comfortable for new shorts to enter. Options traders, meanwhile, are leaning the other way. The put/call ratio has dropped to 0.20, well below its 20-day average of 0.23 and near the 52-week low of 0.17 — a signal that call demand is dominating, with no meaningful appetite for downside protection. Bears are building via stock borrowing; bulls are buying calls.
The Street has been tilting constructive. Stephens raised its target to $155 from $135 on June 16, maintaining Overweight, while Mizuho moved to $140 from $130 earlier in the month. Both are reacting to the April 28 earnings beat, when the stock jumped 14% in a single session and extended the move to 16% over the following week. That result anchored the bull case around AI-driven cyber resilience demand and cross-sell momentum within Commvault's large installed base. The mean analyst target sits at $135, which is close to the current price of $125 — though Stephens and Baird (target $160) both sit materially above consensus, and Jefferies initiated with a Hold at $105 in late April, flagging execution risk. Forward earnings momentum is exceptional: the 12-month forward EPS growth score ranks in the 96th percentile across the universe. Value, however, is the clear weak point — EV/EBITDA of 17.4x and a price-to-book well above the peer median leave little room for disappointment. The bear case from Rubrik and Cohesity gaining share, and management's recent changes to how subscription ARR is calculated, remain active concerns.
Institutional positioning is broadly passive and stable. BlackRock held 14.4% as of end-May, adding modestly. The quant firms are more active: Two Sigma built a new position of 1.1 million shares in Q1, AQR added 686,000 shares, and D.E. Shaw entered with 734,000 shares — all suggesting systematic strategies have been attracted to Commvault's recent momentum profile. The ORTEX short score has drifted slightly higher over the past two weeks, from 43 to 45.8, reflecting the month-long short rebuild, but remains in neutral territory overall.
On the peer side, RBRK — the most directly competitive name — gained 6.4% on the week while CVLT was essentially flat, up just 0.02%. That gap matters: Rubrik is being cited in the bear case as a share-taker, and a week where the would-be disruptor outperforms this sharply is worth noting. PAR also rose 4.7% on the week, while most other correlated names were softer.
The July 28 earnings date is the immediate catalyst to track — specifically whether the subscription ARR trajectory holds, and whether management provides any clearer framing on the revenue methodology change that has unsettled some investors.
