Volatility Brings Changes to Market Leadership

Key takeaways

  • Uncertainty around U.S. government policy – particularly tariffs – is resulting in elevated levels of market volatility, with some names down as much as -50%.
  • Couple this volatility with a change in momentum and many crowded names, particularly within tech and AI, have seen a dramatic shift in fortune as last year’s momentum trade unwinds.

At a high level, it did not seem that bad. As of the second week of March, global equities were down roughly 6%, on par with the sell-off in late December and early January. That said, many of the trades that drove the market higher in 2023 and 2024 are now compromised.

Since the February peak, equity markets experienced a savage reversal in leadership, momentum and investor confidence. Last year’s favorites gave up months, and in some cases years, worth of gains in a matter of a few weeks.

The carnage started with last year’s big winners: tech and AI-related names. Both the ‘Mag 7’ and semiconductor stocks quickly shed -20%, with some of last year’s big winners down as much as -50%. From there, selling spread to other momentum trades, notably consumer discretionary and financials. What happened to abruptly change the investment environment and how should investors navigate this very different environment?

Some uncertainty and a lot of crowding

Apart from the magnitude of the losses, what distinguishes this selloff is the lack of a significant catalyst. To be sure, recent data releases, notably retail sales and the ISM manufacturing survey, have been soft. While by no means terrible, the data has cast some doubt on the economy’s resiliency. Beyond economic data, an unusual degree of uncertainty around U.S. government policy, particularly tariffs, has quickly undercut a narrative of stability and economic growth.

That said, what truly accounts for the magnitude of the sell-off is the extent to which investors were crowded into a few themes, notably AI infrastructure and a bulletproof U.S. consumer. Rather than a dramatic shift in fundamentals, stocks suffering the biggest losses have been caught up in an historic unwind of last year’s momentum trade. Momentum, which generally involves buying stocks with the best 12-month price appreciation, was the top performing strategy in 2024; it has quickly become the worst.
