Stock market today: Indexes trade mixed as investors sift through big bank earnings

• Stock index trades were mixed Tuesday morning.
• Estimate-beating earnings from three banks set a positive tone on Tuesday.
• Oil prices slid over 4% as Mideast tensions seemed to ease.

Stocks were mixed Tuesday morning as traders assessed the latest earnings, though several results before the bell helped strike a positive tone in early trading.

A trio of Wall Street banks — Citigroup, Goldman Sachs, and Bank of America — all topped third-quarter estimates, potentially giving more firepower to this week's rally.

Stocks notched a winning session on Monday that drove the S&P 500 and Dow Jones Industrial Average to record closing highs. Estimate-beating reports from JPMorgan and Wells Fargo last week are also helping drive bullish momentum, though gains were more muted as trade kicked off on Tuesday.

International oil prices were down sharply, with Brent crude falling 4.27% to $74.15.

Though Middle Eastern tensions sparked a rush in oil prices this month, the market's depreciation follows reports that Israel will limit its retaliation against an earlier Iranian missile strike.

While earnings will be this week's focal point, investors will also watch for September's retail sales and initial jobless claims to release on Thursday. Among Fed commentary, governor Adriana Kugler and president Mary Daly will speak on Tuesday.
