Key Takeaways Diversification is losing its effectiveness because modern crises hit almost all industries simultaneously, making broad portfolios more of a burden than protection.
Businesses should rebuild portfolios, divest anything without prospects and concentrate on areas where they have a real competitive advantage.
Companies with a focused portfolio can innovate faster, adjust their product offerings more quickly and manage teams and resources more effectively.
Diversification has long been considered common business sense. “Don’t put all your eggs in one basket” — and you’ll survive any crisis. This logic worked for decades, but today it’s starting to fail.
The problem is that crises themselves have changed. Whereas they used to be industry-specific or regional, they are now systemic. Geopolitics, energy costs, technological shifts — all of these simultaneously impact almost every market. Pandemics, digital transformation and global inflation overlap, creating a new type of shock that cannot be predicted, distributed or “insured” through diversification.
Why diversification is no longer a safety net
In this reality, diversification ceases to be a safety net and becomes a source of additional complexity: Managing disparate business lines is difficult, resources are scattered, and response speed drops.
The old idea that different businesses behave differently in a crisis no longer holds. Recent years have shown the opposite: Multiple lines often decline simultaneously, sometimes all at once. In 2020, even giants like General Electric, traditionally seen as a model of a diversified portfolio, experienced revenue drops across nearly all segments simultaneously. At such times, companies with broad portfolios prove less resilient than those that are focused. Focus provides speed, and speed is more important than scale today.
Large international companies have already drawn this conclusion. Nestlé is actively divesting non-core assets and strengthening key categories, such as health foods and specialized beverages. Kraft Heinz is concentrating on specific product lines, cutting everything non-essential and reinforcing its positions in core segments. Microsoft has focused on cloud services and enterprise solutions, selling off less profitable units. This is not temporary optimization but a strategic shift: depth over breadth.
