There's a lot of earnings and other news out there today, but I think the market is particularly reacting to Greenspan's testimony, ... The markets are expecting a little more growth because of his comments, but that may not be as much as what they wanted to hear.

There are some worries about will the earnings this year support the 2-1/2 year highs that the indexes have recently reached, particularly in an environment where interest rates will be rising.

I think that overall we are in for a pretty good earnings quarter, and that may be a positive for stocks.

Largely people are taking a look at historic information. They're looking at earnings and job cuts, and people are concerned. I think we're going to grind it out until earnings come back.

We're nearing the end of the earnings period, we've already heard from the Fed, and there aren't a lot of big surprises out there for the rest of the month.
