Cars.com Shorts Hold Firm as Stock Hits New Lows

Short positioning reflects genuine conviction rather than a crowded trade. Short interest runs at 11.6% of free float, up roughly 13% over the past month as the stock slid. The borrow market itself remains relaxed: cost to borrow is just 0.52%, easing from recent highs, and availability is generous at 278%, well above the 52-week floor of 215%. That combination, heavy short interest yet easy borrow conditions, means new shorts can still enter cheaply, and there is no obvious squeeze pressure. The ORTEX short score has drifted lower this week to 72.4, down from a peak near 75.1 a week ago, suggesting the acute phase of short accumulation may have passed, at least temporarily.

Options positioning has shifted meaningfully in a less defensive direction. The put/call ratio has dropped sharply to 5.5, nearly two standard deviations below its 20-day average of 10.3. That average itself is elevated, so a PCR of 5.5 still signals a heavily put-skewed book, but the move lower over the past week is notable. Fewer fresh puts are being added even as the stock falls, which could reflect some covering of protection, or simply thin activity in a low-liquidity name.

The Street is cautious without being outright negative. UBS analyst Joseph Spak cut his price target this week from $13 to $11.50, maintaining a Neutral rating, following a prior raise to $13 in August after what was then a constructive print. BTIG holds a Buy with a $14 target, last reiterated in August. The mean target across the coverage sits at $13.33, implying more than 40% upside from current levels, a gap wide enough to flag. With the stock now trading below the CFO's June open-market sales at $9.49 to $9.56, the distance between where insiders were trimming and where the stock has arrived is now essentially zero. Those CFO sales, totalling over $825,000 across two days and filed without a 10b5-1 plan, are worth noting given the subsequent decline.

On valuation, the compression is hard to ignore. The EV/EBITDA multiple has fallen to 4.2x, down from around 4.3x a month ago, and the P/E has contracted to 4.2x. The price-to-book ratio is now barely above 1x at 1.01. The bull case, anchored on a 6x FY27 EBITDA target and 26 to 27% EBITDA margins, requires confidence that the auto dealership channel stabilises and ARPD growth resumes in 2026. The bear case points to flat revenue guidance, competitive pressure in online auto marketplaces, and declining dealership profitability as reasons to doubt that recovery. The factor scores add colour: forward earnings revisions are ranked in the 98th percentile on a 12-month basis, yet the short score ranks in the 4th percentile and analyst recommendation spread is also in the 6th percentile. That divergence between improving forward estimates and deeply negative short and analyst sentiment is the central tension in this name.

Institutional ownership shows no obvious distress selling from the largest holders. FMR holds 15.7% and BlackRock 7.8%, both largely stable. Vanguard, notably, filed a 13G/A in March showing a reduction from 8.72% to zero, a material exit that preceded the sharper weakness this summer. With 29 days until the Q3 print, the next clear test is whether revenue trends and ARPD data from the dealership channel have begun to move in the direction the forward earnings revisions are suggesting.
