European markets failed to react to the overnight slump in Asia, where Japan's Nikkei 225 index closed down by 5.2% earlier this morning. At 7 a.m. EDT, all the major European stock markets were up on the day, possibly helped by the latest eurozone economic sentiment index survey, which rose to 89.4 in May from 88.6 in April.

U.S. markets may be strongly influenced by today's economic reports.

Finally, let's not forget that the Dow's daily movements can add up to serious long-term gains.
