So far tonight,

Intel

(INTC) - Get Report

,

Juniper Networks

(JNPR) - Get Report

and

Applied Micro Circuits

(AMCC)

-- all out with earnings news after the bell -- have risen in postclose action.

Earlier this evening, Intel

reported fourth-quarter earnings that beat reduced expectations by a penny, but warned about results for its upcoming quarter.

The good news -- Intel said that excluding acquisition related charges the company earned 38 cents per share. Analysts had expected the chipmaker to earn 38 cents a share but lowered their consensus estimate to 37 cents just recently, according to

First Call/Thomson Financial

. The semiconductor manufacturer recorded revenue of $8.7 billion for the fourth quarter, in line with Wall Street's expectations.

The bad news -- The chip giant said that it expects revenue in the first quarter to decline about 15% from the fourth quarter "due to seasonal factors and the impact of slowing worldwide economies." That puts first-quarter revenue at about $7.4 billion.

In recent trading, shares of Intel were solidly higher -- up 3.4% to $32.44 on

and advanced 2.8% to $32.25 on

Island

ECN.
