Sell or hold Novo Nordisk?

You bought at $100 and it trades at $48.77. You already know the $100 is a sunk cost. The remaining question turns out to be two questions, and only one of them is hard.
The call
Harvest the loss. Then decide the exposure on 5 August.

Realising the loss is worth doing regardless of what you think of Novo — it does not depend on the investment view at all. Whether the money then goes back into Novo is a genuinely close call, and the number that would settle it arrives in nine days.

Two decisions

One — easy
Should you harvest the loss?
Yes

A $52,522 realised loss on a $50,000 position, because the loss per share is larger than the share price. Worth $7,900–12,500 gross depending on bracket. Doing nothing forgoes it for no reason — that is the one branch that is clearly wrong.

Two — close
Should the money go back in?
Probably, unless you can name better

+4.4% a year after tax against +2.3% for cash. A real if unexciting premium on a 0.36-beta defensive name. Redeploying elsewhere only wins if you have a specific alternative in mind — "something better" is not one.

The two are separable, which is the whole trick. You can harvest the loss and keep the position by selling and buying back 31 days later. So the tax benefit is identical either way and tells you nothing about whether to stay invested. It only tells you not to sit still.

What actually happened to this company

Price broke, not demand. US sales fell 11% in Q1 on lower realised prices, but oral Wegovy did nearly double its expected revenue in its first quarter and passed 3 million prescriptions by June. Novo lost the injectable share war to Eli Lilly — 60.5% to 39.1% by end-2025 — but is currently outselling Lilly's rival pill roughly 7.5 to one on weekly scripts.

Prices fall on 1 January 2027, and that is real: a Medicare negotiated price of $274, a $245 most-favoured-nation price, and a list cut to $675. But these apply to different channels rather than stacking, and Novo's realised net price is already near $569 after rebates — so the commercial cut is closer to neutral than the headline suggests.

The thing the first version missed entirely

Medicare started paying for obesity drugs on 1 July 2026. The GLP-1 Bridge gives roughly 3.8 million eligible beneficiaries a $50 copay, runs through the end of 2027, and covers both of Novo's obesity products but only one of Lilly's.

It comes from the same November 2025 deal that set those price cuts. Quoting the price side as settled fact while omitting the volume side was the single biggest error in the original analysis — the bear case rested on the reset being unoffset, and it is not.

What to do

First
Confirm with a CPA that you have realised gains to offset this year
Without them the deduction is capped at $3,000 a year and this loss takes 18 years to use. That removes most of the reason to act at all.
5 August
Read the half-year results
One number decides the exposure question: US realised price. Falling again supports staying out. Flat or rising means the consensus 2027 estimate is the right one and you should be back in.
Then
Sell and start the 31-day clock
Harvest the loss regardless of which way 5 August goes.
Day 31
Buy it back, unless you can name something better
A close call on a low-beta position you already own should not be settled by an active bet on an unnamed alternative. Do not buy back inside 31 days — it voids the deduction, and the Copenhagen listing is not a safe workaround.
Where this could still be wrong

Toward selling: US realised price falls again on 5 August; the Bridge is not renewed past 2027; Lilly's retatrutide lives up to its Phase 2 data when it files in early 2027. Toward holding more: realised price flattens; Bridge uptake runs ahead of expectations; CagriSema approves cleanly in Q4.

The honest summary is that this is close, and the first version resolved a close position with a confident verdict by making four errors that happened to point the same way. That pattern is worth more attention than the conclusion it produced.

How this was checked

A first version of this analysis concluded sell. It was then put through an independent adversarial review — a separate pass, with no knowledge of the model, instructed to attack the conclusion rather than confirm it. The review found four errors, and all four happened to point the same way:

  1. The tax benefit was used to argue for selling. But you capture it whether you buy back in or not, so it is common to both branches and cannot decide between them. This was the headline of the original.
  2. A gross tax shield was compared against a net return. Harvesting resets your cost basis, so most of the shield is deferred tax rather than money saved — nearer 10% than 25% on a long hold.
  3. A pre-tax cash yield was compared against an equity return while top-bracket rates were applied to the loss calculation. Bill interest is ordinary income; the dividend is qualified. Measured consistently, the position beats cash rather than losing to it.
  4. The 2027 earnings estimate sat 9% below consensus without disclosure, while 2026 matched consensus almost exactly.

It also missed the Medicare GLP-1 Bridge entirely — live three weeks before the original was written, and directly relevant because the bear case rested on the 2027 price cuts being unoffset.

Corrected, the sell case does not hold, and the recommendation above is the result. Four errors leaning the same direction is not four mistakes; it is a model fitted to a conclusion, which is worth knowing about a piece of analysis regardless of what it concludes. The full log is on the final slide of the deck.
