Intel rating, price target cut at Prudential (INTC) By Tomi Kilgore NEW YORK (MarketWatch) -- Intel (INTC) was downgraded to underweight from neutral weight at Prudential, as concerns that a number of challenges will lead to disappointing revenue and margin performance over the next 2 to 4 quarters offsets favorable relative valuation. Analyst Mark Lipacis cut his stock price target to $20 from $31 and lowered his 2006 earnings estimate to $1.45 a share from $1.67. Lipacis expects revenue growth to decelerate, gross margin pressure to increase from rival Advanced Micro Devices and from accelerating growth of low-end products, a chipset shortage and risks associated with a transition of chip manufacturing in 2006. The stock, a component of the Dow industrials, fell 29 cents, or 1.2%, to $23.13 in Instinet pre-open trading. :eek: Q.
