Technology investors apparently were happier than most others Tuesday after the Federal Reserve left the federal funds rate unchanged at its 46-year low of 1%, but didn't hide its intentions of raising rates soon. A statement from the Fed said that because of low inflation and slack use of resources, a move toward higher rates could be pursued at a "measured" pace.

Stocks spiked briefly after the Fed's announcement, but the rally quickly faded as the bank's comments, while soothing, were viewed as no real surprise.
