It was a black week for real estate funds. Aside from the two funds shorting the industry, the average real estate fund fell 4.11% in the five business days ended Thursday.

The latest readings on the housing market have exacerbated what has been a disastrous year for the homebuilding industry. It's difficult to imagine how the mid-October bulletins on the industry could have been much worse.

First, the National Association of Home Builders indicated that a broad measure of member confidence had collapsed to its lowest level since the series began in January of 1985. Gauges of current sales of single-family homes and traffic of new buyers both suffered declines.

A day later, the Commerce Department announced that housing starts crumbled 10% in September following a downward revised 3.2% setback in August, leaving new home construction 31% below September of last year. An indication that the damage was far from finished was that building permits sank 7.3% in September, following up on a setback of 4.8% the prior month.

Then the

Federal Reserve

got its shot in by noting in its "beige book" report that lower prices on new homes, the contraction of construction activity and tightening of the mortgage market would combine to slacken the pace of current economic expansion.

As if that weren't enough, less than a day later, the Conference Board's index of leading indicators rose just 0.3% in September. The biggest drag on their gauge of future economic activity was the drop in building permits.

Leading the retreat are the two exchange-traded funds targeting U.S. homebuilders. The

iShares Dow Jones US Home Construction Index Fund

(ITB) - Get Report

fell 12.28%, while the

SPDR S&P Homebuilders ETF

(XHB) - Get Report

dug a 9.74% hole. Both have earned our lowest possible rating, E-, for poor performance and excess volatility.

You didn't have to own a fund with a specialized investment mandate to feel the pain.

Rising as the rest of the sector crumbled, the two funds shorting the group were virtually the only oasis. In the volatile markets we are seeing, short-term trades in contrarian funds present opportunities. The

(SRPIX) - Get Report

ProFunds Short Real Estate ProFund (SRPIX) gained 4.62% by shorting the Dow Jones U.S. Real Estate Index. Likewise, the

UltraShort Real Estate ProShares

(SRS) - Get Report

became the top performer, returning 8.73% by being leveraged 200% short the same index.

We also found three open-end funds and two exchange-traded funds with portfolios at least 10% exposed to the sector.

Not surprisingly, the two ETFs with the most exposure were the two that topped our worst performers list for the past week. The iShares DJ US Home Construction Index ETF is a pure homebuilding play, with the above 10 major builders making up 57% of its portfolio's value. Its biggest holdings include Champion Enterprises and Toll Brothers. The ETF's shares have been hit with a wrecking ball, down 45.83% in the 12-month period ended Sept. 30. They have collapsed 36.35% in the latest three months alone.

The SPDR S&P Homebuilders ETF takes a more oblique approach to the industry, with home improvement retailers, home furnishings and materials firms among its holdings in addition to homebuilders. Its largest holdings are
