According to @StockMKTNewz, the US stock market opened the session green on December 22, 2025, signaling a risk-on start to trading (Source: @StockMKTNewz tweet, Dec 22, 2025). Traders often monitor BTC and ETH during a strong US equity open because Bitcoin’s correlation with US stock indices has increased notably since 2020, indicating tighter cross-asset linkages that can influence intraday flows (Source: IMF Staff Blog by Tobias Adrian, Tara Iyer, and Mahvash S.

Equity proxies with direct crypto exposure, including Coinbase (COIN) and MicroStrategy (MSTR), remain in focus given Coinbase’s reliance on crypto trading activity and MicroStrategy’s substantial BTC holdings as disclosed in their SEC filings (Source: Coinbase Global, Inc.
