How Much AI Can You Own and Still Sleep Soundly?

As the AI bull market continues to surge, investors face a crucial question: How much of their portfolio should they allocate to a single AI stock before it becomes too risky? In a recent week, AI stocks like Nvidia and Micron Technology experienced significant gains, with Nvidia returning over 1,800% and Micron nearly 1,800% since 2022. However, a sudden downturn in chip stocks reminded investors of the potential volatility.

To navigate this uncertainty, investors should establish a "sleep number" – the maximum percentage they're willing to allow any holding to reach while still feeling comfortable. This number varies from person to person, from 1% for those who prefer a diversified portfolio to 10% for those who are more comfortable with larger individual positions. It's advisable to set this number before it's needed, as it tends to decrease as investors age and approach retirement.

As AI investments continue to pour into tech giants, these companies may grow larger than initially expected. By setting a sleep number, investors can manage their risk and prevent any single stock from dominating their portfolio, potentially leading to financial stress during market downturns. This strategy allows for the continued growth of proven winners while mitigating the impact of a potentially destabilizing concentrated holding.
