Adobe payoff — when the market denies g entirely

When the market stops believing in growth altogether

NVDA's case (last lesson) was about deceleration — g shifting from very high to merely high. Adobe's 2024 case is more dramatic: g shifting from positive to doubtful. The math is the same equation, but with a much bigger denominator move.

The setup. Adobe (ADBE) had been a steady growth software company for years — Photoshop, Illustrator, Premiere, the Creative Cloud subscription business. Strong margins, recurring revenue, classic high-quality compounder. Stock traded at solid premium multiples (P/E in the 30-50 range historically).

Then 2024 happened. AI tools — Midjourney, Stable Diffusion, OpenAI's image and video models, ChatGPT for copywriting — started eating into Adobe's traditional moat. The market began questioning whether Creative Cloud's growth would continue, or whether AI-native competitors would commoditize what Adobe sells.

The Gordon Growth math when g goes from positive to questionable

Suppose pre-questioning, the market priced Adobe with assumptions like r = 9% and g = 6%. Implied r − g = 3%, P/E ≈ 33. Reasonable for a growth software company.

Now the market starts re-thinking g. Maybe AI doesn't kill Adobe outright, but maybe sustainable long-run growth is now 2% instead of 6%. Same r = 9%, but new r − g = 7%. Implied P/E ≈ 14. That's a 60% drop in the multiple alone, with no change in current earnings.

If the market goes further and starts believing g could be near zero (Adobe just maintains its existing customer base, no real growth), r − g = 9%, P/E ≈ 11. From 33 → 11 = a ~67% multiple compression.

In reality, Adobe's stock dropped roughly 30-40% in 2024 (depending on the exact period). The multiple compressed from premium to "value-stock-ish" levels. The math is straightforward: market revised g down sharply.

Why this is even worse than NVDA's case

NVDA's case is about pace — growth slowing from "extremely fast" to "very fast." Math: small g change, moderate denominator move, painful but not catastrophic.

Adobe's case is about direction — growth potentially shifting from positive trend to no trend. Math: big g change, big denominator move, brutal.

The general lesson: the further the market's view of g moves, the bigger the price reaction. Adobe's reset was big because the market reset its view of g by a lot.

Whether the market is right is a different question

This whole math doesn't tell you if Adobe's actually doomed. It tells you the math behind the price drop, given the market's revised view of g.

If you think Adobe will adapt to AI (acquire AI tools, integrate them, keep customers) and growth resumes, then the market's revised g is too low and the stock is undervalued. If you think AI really does commoditize Creative Cloud and Adobe loses share, the market's revision might be right or even insufficient.

Investors who were correct about Adobe's eventual outcome made or saved a lot of money in 2024. The point of this lesson isn't to take a side — it's to understand what the market is actually pricing when a stock crashes without obvious bad news. The crash isn't "irrational"; it's a re-pricing of g.

The takeaway

Adobe's 2024 drop is the math of g repricing — when the market shifts from "this company is growing nicely" to "we're not sure this company is growing." Even with current earnings unchanged, the multiple collapses, dragging the price with it. Same Gordon Growth equation as NVDA's case, but with a much bigger denominator move because the g reset was bigger. The 30-40% drop has a math reason, not just sentiment. Whether the market's repricing is correct is a separate question.
