Financial stocks were falling Wednesday morning, along with the broader markets, as investors continued to worry about whether the proposal to purchase up to $700 billion worth of banks' troubled assets would pass through Congress.

A report that manufacturing activity had contracted far further than expected, indicating that economic activity is rapidly slowing down, helped to push equities down as well. The NYSE Financial Sector Index was up 1.8% at 6,126.25, while the broader

Dow Jones Industrial Average

was off its low of more than 200 points, now down 0.1%, at 10,837.04.

fell sharply as investors continued to worry that its toxic loans may cause the bank to crumble or be bought on the cheap.

surged 60% to $6.55 after the company, also known as Farmer Mac, named a new chief executive and said it would raise $65 million through a preferred stock offering. Buyers of the new shares include firms that lend to the agricultural sector, like
