Venerable San Francisco financial firm Charles Schwab just took an $85 million hit, writing off some debt it owned in Lehman Brothers and Washington Mutual. On the Old Money quarter-mile, Montgomery Street, a small electronic ticker from Schwab offers a barometer. After yesterday's 777.68 plunge, the year-to-date number from the Dow Jones index has gone from -17.1 percent when I walked by on Friday to -20.5 percent yesterday afternoon. I've updated the photo from Google Street View to correctly reflect current trends. [San Jose Mercury News]
