The KBW Bank ETF is down roughly 12% since mid-August even as the S&P 500 touched record highs. The September consumer price index lands Wednesday morning, with consensus around 3.6% headline inflation and 2.5% core, alongside the Federal Reserve's Beige Book. CNBC's Jim Cramer framed the bank selloff as a potential setup for a rally if results beat expectations.
