As vacation time ends on Wall Street, conference season begins. Today, key technology companies gather at the Robertson Stephens Internet Conference and the Credit Suisse First Boston Technology Group Communications Technology Conference. Investors will likely keep these confabs on their radar screens for news from the participants.

Also today, this week's economic indicators trickle in, and the

Purchasing Managers' Non-Manufacturing Index, a measure of service-sector activity but not a major market mover, is released.

Plus:

Heinz

(HNZ)

, the maker of green (and that boring red) ketchup, posts its first-quarter results.
