NEW YORK — Financial companies dragged stocks lower yesterday as already anxious investors grew even more uncertain about the U.S. government's financial overhaul plan and debt problems in Europe.

The Dow Jones industrial average slid 80 points in the final 15 minutes of trading to end with a loss of almost 127.

Investors are worried about limits that could be placed on U.S. banks in a final version of the financial overhaul bill.

A bill that passed the Senate last week is now being reconciled with the House version. The late drop illustrates how jittery traders are in particular about what will happen in Europe.
