Pinterest Shorts Ease, but the Founder Keeps Selling

PINS sits in the middle of its peer group heading into Wednesday's print. Short interest among the closest digital-media names ranges from crowded to light, and Pinterest's 7.3% of float puts it toward the more-shorted end of that spectrum. Peers RDDT and YELP both fell harder on Friday, down 4.0% and 3.4% respectively, while Pinterest dropped 2.7% on the day. Over the week, the stock gained 1.9%, fractionally below the peer median of 2.2%, with SNAP leading the group at 3.4% and Reddit the laggard at minus 7.6%. Options positioning is actually calmer than usual: the put/call ratio has drifted down to 0.74, nearly 1.5 standard deviations below its 20-day average of 0.80, suggesting call activity has picked up relative to puts rather than the reverse. The borrow market is relaxed, with availability at roughly 1,400% of short interest, meaning shares to lend are plentiful, and the cost to borrow has eased a further 8% over the past week to under 0.4%.

The more interesting signal is in short interest itself. Bears have been cutting exposure meaningfully: short interest has fallen 17.6% over the past month, dropping from around 60 million shares in late September to just under 44 million. That reduction coincides almost exactly with the stock's 21% rally over the same period, suggesting short covering has been a meaningful tailwind for price. Whether fresh conviction from either side replaces that flow is one of the questions the earnings release will answer.

The analyst community is broadly constructive but not unanimously so. The consensus sits at buy, with a mean price target near $29, implying roughly 30% upside to the current $22.32 close. Most recent target moves (all from early August, following last quarter's results) went higher, with UBS raising to $33 and Wells Fargo to $31 among those lifting numbers. The sceptic camp, represented by Wedbush and Citigroup at neutral, centres on a structural concern: ad impression growth has slowed sharply from the 40 to 50% range seen earlier, international monetisation remains thin, and bigger platforms continue to crowd Pinterest's advertiser relationships. The bull case rests on 631 million global MAUs, continued AI investment in ranking and bidding, and a buyback programme that has retired roughly 109 million shares for about $2 billion. Forward earnings expectations have been climbing, with the 12-month forward EPS growth factor scoring in the 85th percentile, though the stock's EPS surprise track record is weaker, sitting in just the 17th percentile.

The founder's selling is worth noting in context. Benjamin Silbermann, director and 10% owner, has filed a series of open-market sales in October, each for 46,875 shares at prices between $21.56 and $22.94, all executed under a pre-arranged 10b5-1 plan. The net insider position over 90 days is minus 808,000 shares, worth roughly $16.3 million. Because the trades are plan-driven rather than discretionary, they carry less sentiment weight than opportunistic selling would. Elliott Management remains on the 13D/G register at just under 5%, a passive stake as last disclosed in August, though stakes around that threshold can shift without a further filing.

The print on October 29 will test whether Pinterest's revenue and MAU trajectory can justify the multiple re-rating the stock has already enjoyed, or whether the slowdown in ad impression growth represents a ceiling that buybacks and AI investment alone cannot raise.
