WALL STREET

NEW YORK-- Investor perceptions that stocks are becoming too expensive helped send prices plunging yesterday, putting a down note on a historic week in which the Dow Jones average closed above 3000 for the first time.

The Dow average of 30 industrials fell 33.67 to 2965.59.

Declining issues outnumbered advances by a ratio of about 7-to-4 in nationwide trading of New York Stock Exchange-listed stocks, with 1028 down, 585 up and 464 unchanged.
