When this applies
when a company diversifies into adjacent markets while its existing core market is actually still underappreciated and about to become enormous
The takeaway
Before diversifying into an adjacent 'new business,' size the realistic ceiling of that market against the ceiling of the core business you may be underestimating.
Why it works
Solar was commoditized by state-subsidized Chinese competition and LED was blocked by a small patent cartel, while the core semiconductor market was uncapped by Moore's Law demand growth — so the 'safe diversification' instinct missed the far larger opportunity already in hand.
One level up
The biggest opportunity is often hiding in plain sight inside what looks like 'just the core business.'
Where it stops holding
This stops working when the core business genuinely is reaching a ceiling, in which case adjacent diversification is the correct hedge.
Detail
situation: In 2009 TSMC stood up 'new businesses' in solar cells and LED, placing a trusted CEO-candidate in charge of them, believing they were promising alongside the core IC business.
decision: The company invested resources and leadership time in these adjacent businesses.
outcome: Solar was ruined by heavily subsidized Chinese competition; LED's market was too small and patent-locked by a few incumbents. Both failed, and the executive leading them eventually left to become MediaTek's CEO, while the core IC business became a $600B+ market.
lesson: Chang: 'it's always interesting to me when companies think, oh, we should look at other new businesses, when in reality, semiconductors became a $600 billion a year market... You were already in the best market.'
In their words
It's always interesting to me when companies think, oh, we should look at other new businesses, when in reality, semiconductors became a $600 billion a year market. And, you know, solar is a small fraction of that. LEDs are a small fraction of that. You were already in the best market.
