JDS Uniphase's

(JDSU)

price target and earnings estimates were cut this morning by

Morgan Stanley Dean Witter

, which said it expected declining revenue for the optical fiber company.

Morgan Stanley cut its price target on the company to $50 from $95 and lowered its earnings estimate for the fiscal third quarter to 16 cents a share from 17 cents. The current 18-broker consensus is 17 cents for the quarter. "For the next quarter, we expect a 9% sequential decline in revenue to $925 million, compared to our prior estimate of sequentially flat revenue," the note said. "A broad recovery in visibility looks unlikely."

this morning, citing sluggish booking patterns and the expectation that contract manufacturers will continue to draw down inventories.

Xilinx's revenue growth was lowered to 15% from 20% for 2001, while Altera's was dropped to 4% from 10%. Earnings estimates were also cut for both companies. Earnings per share estimates for Xilinx were dropped to $1.25 from $1.30 and dropped to 89 cents from 94 cents for Altera. Lehman, which has not underwritten for those stocks in the last three years but makes a market in both names, rates both companies "market perform."
