Investors weren't through bidding up tech stocks in the extra session Tuesday, even on a day that saw the

Nasdaq rise 3.6%, as more encouraging earnings news kept buyers interested.

Intel

(INTC) - Get Report

was the volume leader on the Instinet platform following the close, trading up 6.1% to $31.30 after the company met analysts' first-quarter earnings expectations. Even the chipmaker's declaration that it still sees no sign of a broad economic recovery couldn't keep traders from sending the stock higher.

Volume was on the heavy side. In the first hour of extra action, around 7.7 million shares changed hands among the top-20 volume movers on Instinet. Intel accounted for about 3.4 million of those shares.

The majority of the most active stocks in extended trading were gaining ground, but one notable loser was
