Bank of America is a formidable financial titan with a $3.5 trillion balance sheet and a cornerstone of the American economy, holding the second-largest deposit market share in the United States. While the firm has maintained its stronghold among middle-market and retail clientele domestically, Bank of America has continued to hold its own on the global stage, as evidenced by its fourth-largest global trading operation and an investment banking division that regularly finishes in the top four in global league tables. The firm is organized across four segments: consumer banking, global wealth and investment management, global banking, and global markets.

Tighter in drawdowns
Pair moves more tightly when both fall (+67%) than when both rise (+46%) — typical risk-off behaviour.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
