The AI Rally's Moving Goalposts: HSBC Warns Retail Investors

Individual investors who have piled into artificial intelligence stocks may be judging their bets against a target that keeps moving. That is the warning from Maxx Kettner, HSBC's chief multiasset strategist, who says retail investors need to understand how quickly the goalposts shift in AI investing.

The underlying problem is that the case for AI has changed almost as fast as the technology itself. Views on which companies will capture the profits, how long heavy spending will take to show up in revenue, and what growth rates justify today's prices can all move within a single earnings season. An investor who bought on one story may find that the reasons for holding have quietly changed by the time they check their account.

That gap matters most for people who arrive late to a rally. Professional desks typically set exit points in advance, rebalance against benchmarks and limit how much of a portfolio sits in one theme. Many individual investors do the opposite. They buy because a theme has been rising, then judge their results against the last few months of gains rather than against a plan written at the start.

None of this amounts to a call to abandon AI exposure. The more practical lesson is to decide in advance what would prove the original thesis wrong, to check periodically whether the reasons for owning a stock still hold, and to size positions so that a sharp reversal does not derail long-term goals. Investors who want to participate can also spread that exposure across sectors or through diversified funds, rather than concentrating in a handful of high-profile names.
