Constellium: Puts Spike as Wells Fargo Cuts Target

Post-earnings signals on CSTM are pulling in opposite directions. The stock fell 4.5% over the past week, the steepest drop among its closest peers, while put demand and analyst caution both ticked up after the Q3 print.

Wells Fargo Pulls the Target

The sharpest post-earnings move on the analyst desk came from Wells Fargo. Timna Tanners maintained an Overweight rating but cut the price target to $33 from $38, a $5 reduction filed this morning. That follows earlier cuts from UBS (to $32 from $34) and Deutsche Bank (to $36 from $39), both in early October. Barclays set its stall at Equal-Weight with a $28 target on October 14. The mean target across the group now sits at $30.04, against a current price of $24.43, leaving roughly 23% to the consensus. Every firm that moved in October moved lower.

Options Market Reacts

The put/call ratio jumped to 0.457 on October 28, 2.9 standard deviations above its 20-day mean of 0.417. That is the clearest departure from the pre-earnings picture, when the ratio was sitting almost exactly on average. Among CSTM's closest peers, KALU fell 21.5% on the week, a far sharper move, while AP gained 5.6% and CENX rose 1.7%. CSTM's options shift stands out as stock-specific rather than a sector-wide move.

Borrow Market Tells a Different Story

Where options point to hedging activity, the lending market is going the other way. The cost to borrow has dropped 52% over the past week to 0.24%, the lowest level in recent history, as borrow demand evaporates post-earnings. Availability remains effectively uncapped: over 135 million shares sit in the lending pool against fewer than 6 million currently borrowed. Short interest is 4.25% of the free float, down 15.9% over the past month. Nothing in the lending data suggests a fresh wave of short conviction is forming.

Retail Attention Spike

Wikipedia page views and ORTEX traffic for CSTM ran 3.67 standard deviations above their 90-day average around the earnings date. That is a retail attention spike, not a revenue indicator, but it confirms the print drew unusual public interest for a mid-cap aluminum name.
