Dow plunges again

Wall Street extended its losses today, a day after an inflation scare sent the Dow Jones industrial average on its biggest one-day drop in three years and put the Nasdaq composite index in the red for 2006.

Stocks drifted in a narrow range through most of the session but took a sharp turn lower in the last hour of trading, a reflection of how nervous the market remained after the Dow’s 214-point dive on Wednesday.
