A basket of volatile momentum stocks collated by Goldman Sachs suffered on Wednesday its worst session since the COVID pandemic, illustrating how the tech-sector angst currently roiling markets has swiftly turned many big winners into big losers.

"Our 'high beta' or unconstrained momentum basket is on track for its worst day since 2020 (surpassing the post-DeepSeek selloff last January)," said a team at Goldman led by Guillaume Soria in a note published late Wednesday.

That basket includes Enphase Energy (ENPH), SanDisk $(SNDK)$, Lumentum Holdings $(LITE)$ and Western Digital $(WDC)$.

A high-beta stock is one that is significantly more volatile than the overall market benchmark. The momentum investing strategy is buying stocks that have been showing strong performance, or outperformance.

"There is no smoking gun for today's move, it just happens that the market is chasing the strongest earnings revisions possible, and in the midst of that, short term performance technicals got too extreme," said the Goldman team.

They added that the dive for a momentum basket - shown in the chart below - was primarily driven by the strong underperformance of past winners, with a focus on "cyclical high flying themes with high beta," citing memory, rare earth and nonprofitable tech stocks in particular.

"We flagged that Momentum looked stretched and is very crowded (99th percentile over 1yr, 100th percentile over 5 yrs)," they wrote.

Goldman warned that a larger unwind of the winners could cause more pain given high levels of investor exposure to the strategy.

They also noted noted that recent market action has left the volatility of the momentum factor near historic highs (see chart below), compromising what had been the strategy's best start to a year.

Unlike some previous big moves in momentum - such as the DeepSeek shock or news of COVID vaccines - the latest action is more a "consequence of elevated vols, stretched technicals, and higher thematic dispersion with no changes in expectations for some of the higher flying themes," said Goldman.

"However, we have not yet seen major signs of panic or capitulation, and given the very strong run for the factor and elevated positioning, we still think short term hedging makes sense here," they concluded.
