JP Morgan Upgrades CSTM as Post-Earnings Picture Clears

Constellium SE gets a boost from Wall Street's most bullish call in months. The aluminum producer received an upgrade to Overweight from JP Morgan on October 29, even as the stock sits 4.5% lower on the week.

Why this matters: JP Morgan's move cuts against a week of analyst caution and elevated put demand after Q3. The upgrade adds a meaningful divergence to an otherwise cautious post-earnings consensus.

JP Morgan Breaks With the Pack

Bill Peterson at JP Morgan upgraded CSTM to Overweight from Neutral and raised his price target to $35 from $34. At the current price of $24.43, that implies 43% upside. It is a sharply different read from the moves filed by the rest of the desk this week. Wells Fargo's Timna Tanners maintained Overweight but cut the target to $33 from $38, a $5 reduction. UBS cut to $32 from $34 in early October. Deutsche Bank cut to $36 from $39 on the same day. Barclays initiated at Equal-Weight with a $28 target on October 14. Every other firm that moved in October moved lower. JP Morgan is the only one going the other way.

The mean target now stands at $30.04. JP Morgan's $35 sits well above that. Whether it pulls the consensus higher will depend on whether other desks follow the upgrade or hold their reduced targets into Q4.

Retail Attention Spiked Into Earnings

One supporting note from alt data: retail interest in CSTM jumped sharply around the earnings print. Wikipedia views and ORTEX page traffic combined to push a retail attention reading 3.67 standard deviations above its 90-day average as of October 28. This is an attention measure, not a revenue indicator, but the timing is notable given the post-earnings price action.

Options and Borrow Tell a Quieter Story

The put/call ratio came out of earnings at 0.457, 2.9 standard deviations above its 20-day mean of 0.417. That is the same elevated reading reported earlier today. It reflects hedging activity post-print, not a fresh escalation.

On the borrow side, conditions have eased further. Cost to borrow fell 52% over the past week to 0.24%. Availability is effectively uncapped, with over 135 million shares available to lend against fewer than 6 million currently borrowed. There is no pressure in the lending market from either direction.

Short interest sits at 4.25% of the free float, down 15.9% over the past month.
