NEW YORK — The stock market finished mixed today after an early rally faded.
The Dow Jones average of 30 industrials dropped 4.20 to 1,260.71.
But advances outpaced declines by about four to three on the New York Stock Exchange.

The NYSE's composite index rose 0.05 to 103.98.
At the American Stock Exchange, the market-value index was up 2.12 at 228.10.
Stocks had the credit markets working in their favor, with interest rates down considerably for both Treasury bills and bonds.
However, the rally in stocks that began on Wednesday faltered as the session progressed.
Analysts said investing institutions were apparently intent on selling some blue-chip issues as they ready their portfolios for first-quarter reports.
