Rebalancing and an options expiration were the sparks that ignited today's broad-based selloff. And, with pre-announcement negativity added to the mix, even some strong earnings from tech couldn't give the stock market a lift.

It was a very special trading session, as today's triple-witching -- the expiration of equity options, index options and future contracts -- and

S&P 500 rebalancing brought in sellers of all sorts and jacked up the day's volume. Old and new economy stocks, which were already rocked earlier this week with profit warnings, foreign currency issues and skyrocketing energy prices, were weathering some severe volatility, and it didn't clear up in time for the weekend.

"There's a lot of cross currents, with the triple-witch, the S&P rebalancing and the European indices rebalancing, which affects ADRs that trade here," said Peter Boockvar, equity analyst at

Miller Tabak

. "But there's really no rhyme or reason. There is a massive amount of volume and volatility. And, with oil up two bucks, that is a major concern and that is panicking people."

At the closing bell, The

Nasdaq had been knocked down 78.63, or 2%, to 3835.23. Software giant

Oracle

(ORCL) - Get Report

, slipped 6%, after posting its first-quarter earnings last night. The results, which handily beat Street estimates, didn't impress investors, who were looking for strong sales figures from the company.

Meanwhile, the

Dow Jones Industrial Average plummeted 160.47, or 1.4%, to 10,927. With the exception of

ExxonMobil's

(XOM) - Get Report

, which popped 4.4%, most its components were in the red, with tech shaving off about 47 points from the index.

"There are a lot of stocks that have broken down, or are in the process of breaking down," said Sam Ginzburg, senior managing director of equity trading at

Gruntal

. "Large-cap tech is breaking down and we can see the 3600 level on Comp being reached."

But, in the wake of the tech stock takedown, and a triple-digit hack on the Dow, Ginzburg says that we could be poised for a pop at the opening bell, making for another short-selling opportunity. In short selling, an investor would sell stock that he or she does not already own so that they can buy the shares back at a lower price, thus betting that the stock is going to head south.

"Do we hold shorts over weekend? I don't thinks so because you could have another chance to short again -- we might see a bounce on Monday. We have been shorting into any strength in the Comp."

Elsewhere, the S&P 500 slid 15.08, or 1%, to 1465.79, while the small-cap

Russell 2000 shed 8.33, or 1.5%, to 530.88.

In economic news, The CPI fell 0.1% in August, its first drop in 14 years, but a 2.9% decline in energy prices was entirely responsible. The core CPI, which excludes food and energy and is a more stable barometer of inflation trends, rose 0.2%, in line with the average forecast. The sharp rise in oil prices over the last month is expected to produce a considerably less friendly September CPI.

The annual growth rate of the CPI edged down to 3.4% in August from 3.5% in July.

Maytag

(MYG)

put another turn in the side of investor, after warning that its second half would be 8% to 10% below the year-ago report. The appliance maker blamed the shortfall on a loss of business at

Circuit City

(CC) - Get Report

and

Helig-Meyers

(HMY) - Get Report

. The stock sank 6.1%.

But the surging price of crude left oil stocks richly rewarded. Crude oil futures, which tipped over $35 per barrel, shot the

American Stock Exchange Oil Service Index

up 3.4% to a new all time high of 555.61.

Chevron

(CHV)

bounced 3.3%.

For the week, the Dow fell 2.6%, the Nasdaq Composite fell 3.7%, the S&P 500 lost 1.9% and the Russell 2000 fell 0.9%. The Dow Jones transports slipped 2.3%, the

Dow Jones Utility Average

edged up 2.7% and the

American Stock Exchange Composite Index

up 0.4%. TheStreet.com Internet Sector index inched down 0.6% in the latest week.
