Market Movers | Winners: ACVA, FEIM, ATEC | Losers: SMR, SLS, IMSR

Beneath a quiet surface for the major averages, individual stocks saw significant and sometimes persistent moves.

One name on today's list of major losers, Alumis (ALMS), also appears on the one-month list, a sign of persistent weakness. This stands in contrast to a steady session for the broad market, where the S&P 500 returned +0.9%, the Dow Jones Industrial Average returned +1.0%, and the Nasdaq-100 returned +0.9%.

The day's largest percentage moves are below.

A large move is a starting point for research.

The tables appearing earlier are a map of market attention, not a set of instructions. A disciplined reader uses an extreme move as a prompt to check the business behind the stock. The day's top gainer, ACV Auctions (ACVA), saw its stock return +44.2% as its revenue grew 13.3% over the last twelve months. In contrast, the day's weakest name, NuScale Power (SMR), returned -15.7% as its revenue declined 81.0% over the same period.

Either side of these lists can be a lead worth following, with the same follow-up question: does the business back the move? For the winners, our Guidance Momentum screen tracks which companies raised their own forward numbers. For the losers, our Buy the Dip screen flags which marked-down names still have the fundamentals to recover.

Today's Winner Is Tomorrow's Loser Often Enough

The movers list is the most honest picture of single-stock risk the market prints each day: the same volatility that makes the winners column also fills the losers column, and no one reliably knows which side a stock lands on next.

That is the case for owning a disciplined basket instead of chasing the tape. The Trefis High Quality (HQ) Portfolio holds roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Watch the movers for information; let the portfolio do the compounding.
