US stocks rose on Tuesday, pushing the Dow past the 14,000 milestone, boosted by stronger-than-expected earnings and takeover activity.
A brokerage upgrade of American Express Co pushed the credit-card company's stock up 4 per cent and helped lift the Dow average of 30 blue-chip stocks.
Semiconductor stocks gained after Novellus Systems Inc reported stronger-than-expected results, while merger and acquisition activity such as a $12 billion proposal to acquire Lyondell Chemical Co also buoyed stocks.
Shares of financial companies such as State Street Corp, the world's biggest institutional money manager, rose after earnings topped forecasts.
"The markets are up because of the earnings. Though they have just started to come out, what we have seen so far points to another stronger-than-expected earnings season," said Rick Campagna portfolio manager of Provident Investment Council in Pasadena, California.
