The uncertainty over when U.S. Treasury Secretary Henry Paulson may step in to use his new powers to recapitalize Fannie Mae ( FNM) and Freddie Mac ( FRE) roiled the financial sector this week. Paulson is also keeping the market guessing on how nationalizing these mortgage giants would look.

The common shares of Freddie Mac fell 46.8% in the five trading days ended Thursday, Aug. 21. Likewise, Fannie Mae crashed 41.1%. If the Treasury Department takes over and judges these companies to be insolvent, the common shares drop to zero.

The big question is, what will happen to the preferred shares? Worries that a government takeover might have a higher claim to assets than the preferred shares, held by upwards of 8,000 banks, sent financial stocks lower this week. Even if the preferred shares survive, their dividends may be cut.

The average financial fund we track, excluding inverse funds shorting the sector, sank 4.1% for the period.

The two worst-performing funds, both with 200% leverage, fell more than twice as much as the average financial sector fund. The Rydex 2X S&P Select Sector Financial ETF ( RFL) and Ultra Financials ProShares ( UYG) fell 10.6% and 9.2%, respectively.

Similarly, the 150% leveraged ProFunds Financial UltraSector ProFund ( FNPIX), a holder of Freddie and Fannie, fell 7%.

The more narrowly focused ProFunds Banks UltraSector ProFund ( BKPIX) sank 6.9% on 150% leverage. The fund holdings of Frontier Financial ( FTBK) were down 23.2%, Sovereign Bancorp ( SOV) was off 19.3%, and Cathay General Bancorp ( CATY) was down 12%. The drops in these funds can all be attributed to their sizable preferred security exposure.

Economic reports in July showing the index of leading indicators sliding 0.7%, consumer price inflation up 5.6%, and producer price inflation up 9.8% annually cast doubt on a second-half rebound in the economy and on homeowners' ability to afford the mortgages on their homes. This may hasten Treasury Department action on Fannie and Freddie.
