Intel (INTC) - Get Report options were seeing a notable amount of volume again today in the wake of the semiconductor giant's warning Thursday.

The Intel April 35 calls traded more than 12,000 contracts on the

American Stock Exchange

. The calls fell 1 1/6 ($106.25) to 9/16 ($56.25). Meanwhile, some

in-the-money July 37 1/2 puts were seeing a good chunk of volume, with 10,000 contracts trading on the

Pacific Exchange

. The puts rose 5/8 ($62.50) to 8 1/4 ($825). Also on the P-Coast, more than 9,300 of the July 37 1/2 calls changed hands, down 1 ($100) to 1 1/2 ($150). Meanwhile, shares of Intel recently slumped $3.69, or 11%, to $29.56 on volume of 62 million shares.

Intel options volume yesterday was significantly higher than normal, too. A total of 161,670 contracts traded compared to the average daily volume of 78,991, according to

McMillan Analysis

.

And this week, ahead of the news, a major investment bank sold 80,000 Intel July 35 calls, quite a prescient move, an options trader said. Selling call options is a mildly bearish strategy. Investors sell calls on the hope that the options will expire worthless, or below the strike price. It was unclear, though, if the call-selling was done in relation to a large stock position in Intel. Investors often sell calls when they own positions in a stock that looks range-bound in the short term. The call sales generate capital through the premium the buyers pay for the option and -- for an investor holding the stock -- can offset a slip in the stock price and short-term malaise.

Intel said after the close Thursday that first-quarter revenue would be below its previous expectations as the economic slowdown that has hampered PC sales has continued and expanded to the server, networking and communications sectors. The company said it expects revenue in the first quarter to be down about 25% from the fourth quarter's $8.7 billion. The company had

previously said it believed revenue would fall roughly 15% in the first quarter from the fourth quarter. The chip giant also said it's going to cut 5,000 jobs over the next nine months, mostly through attrition.
