The evidence from the provided primary sources strongly and consistently supports the statement. Multiple high-authority sources directly link a decline in US stocks to a concurrent decline in crypto-linked equities. The Charles Schwab market update explicitly states that a fall in tech stocks occurred alongside a drop in crypto-related stocks like Coinbase (COIN) and MicroStrategy (MSTR), attributing both to the same 'risk-off sentiment.' This is corroborated by TradingView, which notes that Coinbase's decline aligns with a broader market downturn caused by a 'selloff of risk-on assets.' Furthermore, a Yahoo Finance page for Coinbase prominently features a headline about US stocks sinking, directly contextualizing the crypto-linked equity's performance within a broader market decline. The remaining relevant sources provide access to the primary historical price data for both a US market benchmark (SPDR S&P 500 ETF) and a key crypto-linked stock (Coinbase), allowing for direct verification of the two corresponding declines mentioned in the statement. There is no conflicting evidence among the usable, high-authority sources.
