I don't expect them to stay that high for long but it wouldn't surprise me if they moved higher before they drop, just because we do have lower inventories and it's not likely OPEC's going to raise production any time soon,
Certainly Nortel selling its optical business to Corning and then taking half of the company is probably the biggest story on Monday as far as news that moved the markets.
Basically what we're seeing is stocks that reported expected or better than expected first-quarter earnings have moved up, while any company that has really disappointed has gotten slammed. The market is looking for direction.
The fact that the market hasn't moved strongly either up or down all week, really says that it's looking for direction.
