Everything on Portfolio Risk

The concentration of the Nasdaq 100 in the top 12 stocks exceeds 55%, creating significant single-name risk. This concentration has driven recent returns but increases portfolio volatility and sensitivity to individual company performance.

Impact: Passive investors face higher volatility than in broader indices, requiring active rebalancing or diversification to manage risk exposure.
