U.S. stock futures fell sharply early Tuesday after top Wall Street bank chiefs warned of a possible market pull-back.
The CEOs of major firms said stocks may see a 10-15% drop within the next 12-24 months.
Futures tied to the S&P 500 dropped about 1%, and Nasdaq futures slid roughly 1.3%.
Technology companies that drove recent gains also weakened ahead of key earnings reports.
The warning comes amid concerns that tech valuations are stretched and investor sentiment is shifting.
