Big-box retailer Target sank 9.9 per cent after forecasting fourth-quarter comparable sales would be anywhere from flat to up 2 per cent. The company's fourth-quarter profit estimate also was lower than analysts expected.

General Electric gained 2 per cent, rallying a bit after two days of steep declines at disappointment over a turnaround plan that disappointed investors.

Bank of America gained 2.1 per cent after Warren Buffett's Berkshire Hathaway disclosed a larger stake in the company.
