Target Corp gave a cautious outlook on Wednesday after reporting a lower-than-expected increase in quarterly sales at established stores because of unseasonable weather and weaker demand for electronics and groceries. Shares of the company fell as much as 11 percent, their biggest intraday decline since December 2008, as investors shrugged off higher-than-expected earnings. The stock was down 7.1 percent at $68.27 in the early afternoon.
