Why this matters — Three distinct ORTEX data streams on American Express have aligned simultaneously: a sharp cost-to-borrow collapse, a post-earnings short interest unwind, and a normalising options put/call ratio. Together they paint a coherent picture of bearish positioning being dismantled following the April 23rd earnings report.
Cost to Borrow collapses. AXP's cost to borrow plunged 50% in a single week to 0.238% as of April 24th. That is the sharpest decline in a month. The CTB peaked near 0.59% in early April. It has now fallen to its lowest point in the 30-day window. A falling CTB signals lenders are seeing reduced demand from short sellers.
Short interest unwinds fast. Shares short dropped 14.5% in one day and 16.6% over the week to 10.67 million as of April 24th. This follows the April 23rd earnings release, which sent the stock down 5.7% on the day. Short sellers who built positions into the event appear to be covering. The month-on-month figure is still up 12%, showing the build-up was real — but the reversal is now equally sharp.
Options sentiment normalises. The put/call ratio sat at 0.47 ahead of earnings — 2.6 standard deviations below the 20-day mean. After the earnings drop, the PCR has moved back to 0.53, almost exactly in line with the 20-day average of 0.52. The pre-earnings call skew has unwound. Options positioning is now neutral.
Analysts diverged sharply on the day results dropped. B of A Securities raised its target to $387, maintaining Buy. BTIG reiterated Sell with a $285 target. Barclays trimmed its target marginally to $322 at Equal-Weight. The mean analyst target stands at $361.80 — a 15% premium to the current price of $314.08. Capital Research added 2.46 million shares in Q1, the largest institutional addition among top holders. Berkshire Hathaway holds 151.6 million shares — 22.2% of the company — unchanged.
The current short unwind mirrors a pattern from mid-March, when shares short fell from ~9.8 million to ~9.5 million around the prior earnings cycle. The difference this time: the pre-earnings build was larger (peaking above 12.7 million shares) and the post-earnings unwind is faster.
