US Stocks Close Lower; MARA Falls 10.16%, Riot Platforms Drops 10.05%

The outsized drop in crypto-linked equities relative to the broad indices points to a sector-specific de-rating rather than a market-wide risk event. That divergence matters because names like MARA, Riot and MSTR have increasingly traded as leveraged proxies for bitcoin exposure, so their underperformance suggests either forced deleveraging or a repricing of that premium. Whether the gap between these equities and the underlying assets persists, or mean-reverts once broader tech stabilizes, is the open question.
