Three days of intense selling knocked 409.59 points off the

Dow Jones Industrial Average

. This blow-up was sparked by rising interest rates. For the week ending Thursday, June 7, the yield on the generic 10-year U.S. government bond rose 24 basis points to 5.13% -- its highest level in almost a year.

The expectation of interest rates continuing their climb hurt stocks across all sectors. Looking at unleveraged funds only, energy funds were down by as much as 3.8% for the five trading days between May 31 and June 7.

The worst-performing health care funds lost as much as 3.9%, while financial funds lost 4.3% and precious metals were pounded down 5.3%. When the market is dropping, even holdings of socially responsible funds get tossed out the window. These funds lost as much as 4.3%.

Not to be outdone, the utility sector, renown for its interest rate sensitivity, offered up an example of one unleveraged fund being chopped down by 9.35%. On average, the utility funds we track lost an amazing 5.10%, when you exclude inverse funds that short the sector.

ProFunds Utilites UltraSector ProFund (UTPSX) slashed off 9.75%. Both funds follow the Dow Jones U.S. Utilities Index.

Investors tend to hold utility stocks for their good yields. But with higher risk-free rates, these stocks can become comparatively less attractive. In the past five trading days, members of the Dow Jones U.S. Utilities Index sank substantially.

Macquarie/First Trust Global Infrastructure/Utilities Dividend & Income Fund (MFD) were Pennon Group, off 7.32%, Red Electrica de Espana off 5.17%, and Kelda Group PLC off 5.14%.

Being a closed-end fund that does not have to trade at its net asset value, this fund fell further than its holdings, dropping 9.35%. It also shows that rising rates are not just a U.S. phenomenon.

Even with an unbelievable one week return of 14.04%, the

UltraShort Utilites ProShares

(SDP) - Get Report

is still down 10.72% since it was launched Feb. 1. If interest rates continue to rise, this 200% negatively leveraged fund has a good shot at breaking even.

Also, not to be believed is the 0.10% positive return of the

First Trust Utilities AlphaDEX Fund

(FXU) - Get Report

. This illiquid fund didn't trade on June 6 or June 7, nor did it last week on May 31 or June 1. So, the 0.10% figure represents the gain from $19.76 on May 30 to $19.78 on June 5. Over the comparable week, the fund's holdings averaged a loss of 5.44% -- with only three holdings rising while 51 declined.

Friday morning, the yield on the 10-year U.S. government bond continued its climb, peaking at 5.242%. This attracted bond investors whose buying drove the yield down to as low as 5.101% and alleviated some of the pressure on stocks. It remains to be seen whether the resurgence in stocks on Friday was a dead-cat bounce or a phoenix rising from the ashes.
