The strength in the market is being lead by the NASDAQ, followed by the S&P and then the Dow. The NASDAQ tends to usually lead the market, therefore with many of the big names already reporting earnings; a slightly bullish bias could be expected in the following week.
Las week the S&P and Dow both violated the prior week’s low and failed to make a new high after 6 weeks of progressively higher movement. The NSADAQ however, did make a new high and did not violate the prior week’s low.
