Another day, another huge decline in the Dow Jones Industrial Average.

Stocks tumbled yet again today as widespread panic over subprime mortgages, worries over retail sales and general unease about the future caused investors to shift their money into safe havens such as mattresses, refrigerators and crawlspaces in their homes. Pleas for calm by pundits such as Citigroup Inc. (NYSE:C) strategist Tobias Levkovich, who today urged investors "not to succumb to an emotional desire to sell before things get worse" were ignored.

What's remarkable about this more than 100 point sell-off is that it came after the Fed pumped $24 billion in temporary funds into the economy. Central banks in Japan, Europe and Australia also responded to the crisis, according to Bloomberg News.

Still, the market isn't stable and bad signs abound.

Countrywide Financial Corp. (NYSE: CFC) scared the bejesus out of the market yesterday with its warning of "unprecedented disruptions." France's BNP Paribas froze three investment funds that until fairly recently were worth about $2.2 billion because of losses in the U.S. mortgage market and apartment builder Tarragon Corp (NASDAQ: TARR) raised doubts about its ability to continue in business, according to the Wall Street Journal.

About the only good news came from the Fed's declaration this morning that it would provide liquidity "as necessary" to bolster the market.

Smart investors know that it's always darkest before the dawn, but that doesn't make times any less dark.
