AAPL up nearly 14% among broad market gains

Shares of Apple stock closed higher today, among a widespread buying spree that pushed the Dow Industrials up a record-breaking 936 points.

AAPL closed at $110.26 per share, an increase of $13.46. Nearly 55 million shares changed hands.

Microsoft, Dell, Google, HP, Sun, and AT&T also posted double-digit percentage gains for the day.

Analyst firm Sanford C. Bernstein upgraded Apple stock to "outperform" this morning, saying the company's short-term prognosis looks good, despite the dip in the market. Bernstein did, however, cut its price target by $50 to $135.

AAPL was up slightly in after-hours trading.
