Northwestern Mutual manager calls Nasdaq momentum unwind a record book event

Matt Stucky, chief portfolio manager for equities at Northwestern Mutual Wealth Management, described Thursday's sell-off in the Nasdaq Composite as a momentum unwind "for the record books." In an interview with Yahoo Finance Senior Reporter Brooke DiPalma, Stucky characterized the trading session as a sharp instance of momentum selling, noting that the first two quarters of 2026 had been defined by a massive beta and momentum trade led by semiconductors.

Stucky explained that this dynamic shifted in the third quarter as interest rates backed up, creating a catalyst for capital to rotate from momentum strategies into quality factors. Although rates pulled back sharply during the interview, Stucky argued that the third-quarter rate environment had already forced momentum to roll over. He viewed Thursday's session as an outsized microcosm of this third-quarter trend, where momentum assets continued to be sold off heavily.

When asked if the sell-off was justified, Stucky stated that it was probably not justified in terms of raw fundamentals. He suggested that when portfolio managers and institutional traders swap out in factor regimes, individual stocks can be "thrown out with the bath water." He pointed to the semiconductor sector as a case in point, distinguishing between general market sentiment and specific supply and demand conditions.

Stucky noted that the market for compute has continued to tighten during September. He cited rental rates in the spot market for Nvidia Blackwell chips as evidence, stating that they are more expensive today than they were a month ago. He described this tightening of demand relative to supply as a bullish signal for semiconductor investors.

However, Stucky acknowledged headwinds in the financing environment. He observed that financing costs are higher and that investors remain concerned about new cloud business models. He also noted that prices for bonds associated with these models continue to rise, a development he characterized as negative. Despite these financing pressures, Stucky maintained that the fundamental demand for compute hardware had strengthened over the last month.
