CMI enters its May 12 Q1 earnings call with a rare alignment: the stock is up 23% in a month, the Street is scrambling to lift targets, and the borrow market is one of the loosest in the industrial universe. The setup is bullish in almost every direction — which is exactly what makes it worth interrogating before the catalyst hits.
The analyst story is the most compelling thing happening on CMI right now. Morgan Stanley and Wells Fargo both raised their targets on May 6, the same day as this note, with Wells Fargo moving its objective from $693 to $794 — a 15% lift — while maintaining its Overweight rating. Morgan Stanley followed with a $675-to-$752 revision under the same positive rating. That pair of bellwether upgrades follows a pattern that's been building for weeks: Truist lifted to $730 on April 20, Citi moved to $710 on April 13, and Wells Fargo itself had already raised once that month. Every recent analyst move has been a target increase, with no downgrades in the recent window. The consensus mean now sits at $693, modestly below the current price of $674.88 — the Street is effectively playing catch-up to a stock that has already moved. That is not a bearish signal, but it does indicate that multiple expansion has arrived before the earnings confirmation.
The bull case rests on power generation. CMI's Power Systems segment posted 18% sales growth in the most recent quarter, and the company is guiding for 3-8% full-year revenue growth, implying revenues between roughly $34.7 billion and $36.4 billion. EPS momentum factor scores rank in the 87th percentile on a 30-day basis and the 70th percentile over 90 days — consistency, not just a one-quarter pop. Forward earnings estimates are rising at a rate that puts CMI in the 91st percentile for year-on-year increase. The bears, however, point to margin pressure: gross margins fell 120 basis points year-on-year to 22.9%, with North American truck volumes weak and tariffs biting. Revenue in China is also under pressure as heavy-duty truck demand fades. The valuation at 22.7x trailing earnings and 14.5x EV/EBITDA reflects a market that has priced in the recovery in power generation but may be under-weighting the truck cycle headwinds.
Positioning tells an unambiguously relaxed story. Short interest is just 1.5% of the free float — low enough that short sellers are not a meaningful price factor in either direction. The borrow market is exceptionally loose: availability is deep, cost to borrow has collapsed 73% over the past month to just 0.37%, and the ORTEX short score of 30 places CMI in a zone with little short conviction. The one notable data point in the short history is a jump in shares short from roughly 1.64 million in early April to around 2.23 million by April 23, followed by a steady pullback toward 2.07 million by May 5. That mid-April build — coinciding with the tariff-driven market selloff — has since been partially unwound as the stock recovered. Options lean modestly bullish: the put/call ratio of 0.88 is slightly below its 20-day average of 0.91, and a z-score of -0.87 signals marginally more call-side activity than usual, though neither reading is extreme.
On the institutional side, Vanguard (12.8% of shares), BlackRock (8.5%), and State Street (4.7%) dominate the register — passive index ownership is the baseline narrative. The most notable recent active flow is FMR (Fidelity), which added 1.48 million shares in its most recent filing, the largest incremental position change among the top holders. That's a meaningful addition for an active manager and points to growing conviction in the earnings recovery story. On insiders, the picture is less directional: CEO Jennifer Rumsey received and sold shares in late February (a sell of 19,450 shares at roughly $584 for $11.4 million), which is typical of an award-and-sell pattern rather than a directional call on the stock. Significance scores on those trades were low.
The one comparable earnings reaction in the data is the February 5 Q4 2025 print, where CMI fell 4.6% on the day and another 2.8% over the subsequent week. The stock was trading near $565 at that time; it has since rallied more than 19% to $674.88, absorbing that negative reaction and then some. The RSI at 68.6 shows momentum is elevated but not yet in overbought territory. Closest peer CAT is up 10.6% on the week — in fact the strongest of CMI's correlated peers — while PH has shed 9.3% over the same period, a notable divergence in what is otherwise a tightly correlated industrial cluster.
The May 12 earnings call is the next meaningful test: the question isn't whether CMI's power generation franchise is growing, it's whether the margin trajectory in trucks and the China weakness are worse than the raised targets imply.
