Limits of diversification

Diversification spreads risk across more holdings, countries or asset classes. It typically reduces single-name blow-ups. It does not erase market risk.

In more detail

When many holdings fall together (a crash, a liquidity freeze, shared factors), diversification helps only so far. A fund with many names in one sector or region is less diversified than the count suggests. Labels and marketing do not replace real independence of risks.

Background

Finmon recommends no mix and no product. Spreading money around is a mechanism with limits. It is not a shield and not a guarantee of return. This sits next to risk, ETFs, asset classes, and theme concentration.

An example

You hold ten tech shares instead of one. A single company failure hurts less. A sector crash can still hit all ten at once.

A common misconception

Many holdings mean no market risk left.

Diversification softens single failures. Shared crashes and factors can still hit.
