McKesson enters the week with shorts covering aggressively and options tilting toward calls — an unusual degree of alignment for a stock still trading 10% below the Street's consensus target ahead of its August 5 report.
The most striking data point is the pace of short covering. Short interest has dropped nearly 18% over the past month, falling from a June peak near 4.8% of the free float to 3.2% now — the lowest level in the trailing 30-day window. That retreat accelerated this week: a single-session drop of nearly 9% on July 23 pulled shares short below 4 million. The borrow market reflects no friction whatsoever. Cost to borrow is running at 0.45%, down 14% on the week, and availability is extraordinarily loose — shares available to borrow amount to roughly 63 times current short interest. There is no squeeze dynamic here; shorts are simply walking away.
Options positioning reinforces that read, though with a note of caution. The put/call ratio has edged back up slightly to 0.54 from the 0.53 low flagged in the prior note — still more than one standard deviation below the 20-day average of 0.57, and near the 52-week low of 0.50. That keeps the options market firmly in call-heavy territory. Traders added puts only marginally on Friday, and the overall posture remains one of leaning into upside rather than hedging against a miss. The prior note noted this shift arriving unusually fast after the July 22 print; the reading has held through the week, which gives it more weight.
The Street picture is constructive but not uniform. Citigroup raised its target to $1,000 from $945 on July 24, maintaining a Buy — the freshest analyst action and one that adds momentum to the bull case heading into August 5. TD Cowen kept its Buy but trimmed slightly to $989, reflecting modest caution without a change in conviction. The consensus mean target sits at $945, implying roughly 12% upside from the current price of $840.90. That gap has persisted through several quarters of target cuts — JPMorgan, Barclays, and others lowered targets after the May print — so the Street acknowledges execution risks even while holding positive ratings. The EV/EBITDA multiple of 13.6x has drifted slightly lower over the past 30 days, suggesting the market is not yet re-rating the stock ahead of results. The PE of 17.6x is up about 1.4 points over the month, tracking the price recovery. The EPS surprise factor score ranks in the 76th percentile, meaning McKesson has a consistent track record of beating consensus.
Insider activity over the past 90 days tells a more complicated story. The CEO Brian Scott Tyler sold 8,463 shares on July 7 at $793.56 — a $6.7 million transaction — following two earlier tranches in June at lower prices. Several other C-suite executives also sold in May and June: the Chief Legal Officer, Chief Strategy Officer, and HR Director all made material disposals. Net insider activity over the 90-day window reflects $27.5 million in sales across approximately 35,600 net shares. The significance scores are low (rated 2 out of 10 across the board), which typically indicates pre-planned trading programs rather than discretionary selling. Still, the volume of executive selling in the weeks before a scheduled earnings date is worth noting, even if each individual trade appears routine.
Peer performance adds modest context. CAH was flat on the week while COR edged slightly higher — both close correlates to MCK. LH outperformed the group, up nearly 5% on the week, while HSIC and VMD lagged with losses around 3%. MCK's own week was essentially flat, down 0.06%, which makes the month's 10% gain look more like a one-directional move that has now paused.
The next test is entirely determined by the August 5 report. The two most recent earnings prints produced small negative next-day moves — roughly half a percent and just over one percent respectively — with a modest recovery over the following five days. Positioning heading into that date will be the key variable to watch: whether the call-heavy options skew holds, and whether short covering continues or stabilises near current levels.
