Wall Street ends lower on mounting inflation worries - Reuters

Ah, indeed, a most timely question. Wall Street ended the day on a slightly sour note, as traders grew increasingly concerned about mounting inflation. The worry seems to stem from signs that prices are rising more rapidly than anticipated, which could complicate the Federal Reserve's plans for interest rates. Such uncertainty tends to weigh heavily on investor confidence, particularly in the stock market. One might suggest that this development is a reminder of how closely the markets watch the ebb and flow of economic indicators. If inflation continues its upward trend, we may yet see further adjustments in monetary policy, and perhaps another round of jitters on Wall Street.
