Amcor Call Skew Holds as Stock Adds to Post-Print Gains

AMCOR approaches its November 3 results with options traders still leaning bullish and the stock extending the gains that followed the October 27 print, though a quietly rising short position adds a note of caution to the setup.

The options picture remains the dominant signal. The put/call ratio has eased further to 0.45, now running about one standard deviation below its 20-day average of 0.50. Call-side demand has been the consistent theme over the past two weeks, even as the stock climbed 2.8% on the week and 11.6% over the past month to close at $47.39. The borrow market contributes nothing alarming: availability is 222%, meaning roughly two shares are available to borrow for every one currently shorted, and cost to borrow is a negligible 0.50%. Neither metric points to stress in the lending pool.

Where the picture is less clean is in short interest. Shares short have risen 40% over the past month, reaching just over 1% of the free float. That absolute level is too low to generate squeeze pressure, but the pace of accumulation is notable: bears have nearly doubled their position since mid-September. The ORTEX short score has drifted up to 57.6, its highest reading in the 10-day window, consistent with incremental bearish conviction building even as the stock has rallied sharply.

The analyst debate pits a still-constructive majority against a more cautious recent tone. JP Morgan's August downgrade to Neutral from Overweight is the freshest action from a bellwether firm. Citigroup and BofA remain buyers, with targets of $52 and $51 respectively. UBS initiated at Buy with a $56 target in August. The mean consensus target of $50.07 implies about 6% upside from the current price, a narrower gap than the 9% implied before the last print as the stock has continued higher. On valuation, the trailing PE has expanded to just over 11x, up more than one point in 30 days, while EV/EBITDA climbed to 9.3x. The earnings yield factor score of 75 suggests the stock is not yet stretched on that measure, but forward EPS momentum ranks in the bottom third of the universe (score of 28), a tension the November print will be asked to resolve.

Ownership adds a mildly supportive data point. Invesco added 13.4 million shares in the quarter to September, making it the largest single incremental buyer among the top holders. BlackRock and State Street also added modestly. The pattern is consistent with passive and active managers adding on price weakness earlier in the year rather than chasing the recent rally.

The November 3 print is therefore less a question of whether Amcor is growing and more a test of whether the volume and margin trajectory justifies a stock now trading 11% higher than it was a month ago, against a backdrop where short sellers have quietly been rebuilding positions throughout the run.
