American Express heads into the week with a quietly interesting tension: short sellers have rebuilt positions at the fastest pace in months, even as the stock's fundamental story remains broadly intact.
The price tells part of the story. AXP closed at $309.31 on May 19, down 1.6% on the week and nearly 7% off its April level. That puts it below most analyst price targets but well within range of the Street's consensus view. The underperformance is notable against the backdrop of a Q1 earnings print that came in strong — revenue up 8% year-over-year, full-year guidance raised — suggesting the market may be pricing in something the quarterly numbers have not yet shown.
The short-interest picture is the clearest signal worth watching. Shorts have rebuilt aggressively since early May. SI as a percentage of the free float has jumped from around 2.2% on May 8 to 2.6% by May 19 — a move of roughly 18% in short shares in under two weeks. Over the past month, total shorted shares are up nearly 11%. That said, the absolute level remains modest at under 3% of float, and the borrow market is far from stressed. Cost to borrow is just 0.35%, barely above where it was a month ago. Availability is extraordinarily loose — roughly 7,086% of outstanding short interest, meaning the lending pool dwarfs actual demand by orders of magnitude. There is no squeeze dynamic here. The short rebuild looks more like tactical positioning around a stock that has softened than any structural bearish thesis bearing fruit.
Options are mildly cautious but not alarming. The put/call ratio came in at 0.55, a touch above its 20-day average of 0.52. The z-score sits at roughly 0.9 — elevated relative to recent history but nowhere near the kind of defensive extreme that would flag a real shift in sentiment. The 52-week high on the PCR is 0.84, so current positioning is solidly mid-range. Options traders are hedging at the margin, not rushing for protection.
The analyst community is broadly constructive, though the direction of travel has been uneven. After Q1 results landed in late April, Goldman Sachs raised its target to $400 while keeping a Buy, and Bank of America moved to $387. Evercore nudged its target higher to $345 but stayed at In-Line. Against that, Barclays trimmed to $322 and JPMorgan had already cut to $325 in early April during the broader macro drawdown. The mean target of $360 sits about 16% above the current price — a reasonable spread that implies the Street collectively sees value at these levels, even if conviction isn't unanimous. The one dissenting voice is BTIG, which has maintained a Sell with a $285 target. Valuation multiples back up the broadly supportive read: the trailing P/E is around 16.7x, down more than 1.3 turns over the past 30 days as the price has slipped. Price-to-book has also compressed, falling to 5.6x from above 6x a month ago.
The bull-bear debate on AXP is increasingly about growth composition. Bulls point to new account additions across both consumer and commercial segments, which are absorbing the slack from any deceleration in same-customer spend. Fee-paying cardholders continue to grow, and travel-related volumes have remained resilient. Bears counter with a different read: new card acquisition has been declining both sequentially and year-over-year, and without aggressive marketing spend, revenue growth in the 5-8% range looks more like maintenance mode than expansion. The Platinum Card refresh may have flattered the recent quarter; the underlying trend is what the next print will need to address.
Berkshire Hathaway holds 22% of shares outstanding and has not moved its position in recent filings — a ballast that tends to dampen vol on the downside and limit any meaningful short build. The next earnings date is July 24. With shorts at a 30-day high and the stock down from its recent peak, that print becomes the pivot point around which current positioning will be tested.
