Wall Street suffered a massive selloff Friday. The S&P 500 lost roughly $1.8 trillion in market value, dropping 2.64% to close at 7,383.74. The Nasdaq Composite recorded its largest single-day point drop in history, plunging 1,121.53 points, or 4.18%, to finish at 25,709.43.

The catalyst was an unexpectedly strong jobs report from the Bureau of Labor Statistics. Robust hiring data sent Treasury yields higher and effectively ended hopes that the Federal Reserve might cut interest rates soon.

This is the classic "good news is bad news" dynamic. Strong hiring reduces the Fed's incentive to ease monetary policy. Higher-for-longer interest rates make borrowing more expensive, compress valuations on growth stocks, and push investors away from risk assets.

The selloff snapped the S&P 500's nine-week winning streak. Technology, AI, and semiconductor stocks were hit hardest, as their valuations depend heavily on future earnings projections sensitive to rate expectations.

Bitcoin slipped below $60,000 for the first time since October 2024. MicroStrategy, Coinbase, and Robinhood all fell between 6.5% and 11%. The correlation between equities and crypto during Friday's selloff shows that digital assets trade like risk assets, not digital gold.

The trigger was a strong jobs report, not a geopolitical crisis. Persistent economic strength keeping the Fed on the sidelines isn't going away with a single data point. The cross-market contagion should remind investors that diversification between stocks and crypto offers less protection than many assume when the macro environment shifts.

Traders should watch Treasury yields closely. If the 10-year yield continues climbing, pressure on both equities and crypto is likely to persist.
