With crude oil at a record high, the U.S. dollar being taken out and shot and mortgage insurance companies on the hot seat, I fully expected to be writing about energy, precious metal, or financial funds today. However, the carnage in those sectors was dwarfed by the electromagnetic tsunami hitting technology funds.

The worst-performing technology fund was slammed for 12.73% last week, compared with losses of 7.12% in energy, 5.81% in precious metals, or 7.89% in financials. Aside from the two short funds, only eight of the 152 technology funds we track avoided a down week. The average non-short fund lost 2.33% for the week ending Thursday, Oct. 25.

Nine of the 10 funds on the worst-performer list are either semiconductor funds or electronics funds holding mostly semiconductor stocks. The

Ultra Semiconductor ProShares


, which is leveraged to twice the Dow Jones U.S. Semiconductor Index, chipped portfolios for 12.73%. At 150% leverage, the


ProFunds Semiconductor UltraSector ProFund (SMPIX) lost 10.34% of its value over the past five trading days.

lost one-fifth of its value, down 20.29%, on weaker-than-expected projections for fourth quarter sales. And



shares were walloped for 20.28% when third-quarter profit fell 75%.

It is important to know the industry allocations of the funds you hold to avoid excess concentrations and explain why funds gain or lose value. For example, the


Fidelity Advisor Electronics Fund (FELAX) is made up of less than 4% electronics stocks and about 85% semiconductor stocks.

One of FELAX's holdings,



, shed 20.25%. The company's latest, ultra-cool product lets you watch computer-downloaded movies and other digital video on your home TV. Unfortunately, SanDisk also announced that it is initiating 25 patent lawsuits. Defending technological innovation can be expensive. Another holding,

Nanophase Technologies


, sliced off 24.70% of its value. The company's earnings release proclaimed the 11th consecutive quarter of year-over-year revenue growth without mentioning the 39 consecutive quarters of negative diluted earnings from continuing operations.

Slashing off 8.01% of shareholding value, the

iShares S&P GSTI Semiconductor Index Fund


closely followed its underlying index. The one position causing the most damage was

AMIS Holdings


, off 22.77% as the company's audit committee reviews its inventory cost valuation for impacts on third quarter financial reporting.

Traveling at "warp 9" for this short period of time, the

UltraShort Semiconductors ProShares


replicated the 200% opposite of the Dow Jones U.S. Semiconductor Index's daily performance, gaining 14.46% for the week. This fund has still lost money over the last year but works well for catching short-term semiconductor downdrafts.

The other 200% short fund

, UltraShort Technology ProShares


added 4.30% by tracking inverse returns of the Dow Jones U.S. Technology Index. Earnings reports and lower estimates of revenue or profits gutted index constituents



by 24.43

%, F5 Networks


by 20.49% and



by 20.40%.

Today, semiconductors are in everything. Even my toothbrush has one. As orders for chips for new products must be made well in advance, semiconductor orders are a telling sign of business sales expectations. The trouble we are seeing in the semiconductor industry does not bode well for predictions of fourth-quarter GDP.
