US Stocks Close Mixed; MARA Falls 5.79%, Riot Platforms Down 5.31%

The divergence is the story: a modestly higher Nasdaq alongside a softer Dow, yet crypto-exposed equities sold off harder than the broad tape, suggesting the weakness was specific to that complex rather than a market-wide risk-off move. The spread of declines across miners, a brokerage and payments names points to sentiment toward crypto-linked exposure broadly, not one company's news. Whether that underperformance persists independently of the major averages is the open question.
