The stock market with all of its intraday gyrations finishes the week up nicely. Following a decline on Monday, the last three days have culminated in a 1.8% rise in the S&P 500. In contrast to last week, when good news was bad, investors decided the liked the sound of a roaring economy, especially if Fed Chairman Ben Bernanke doesn’t drown it out with the inflation drum. On Tuesday, the government reported the strongest monthly gain in retail sales in nearly two years confirming that the economy is as strong as ever. The Dow industrials rose 136 points, or 1.25% to 11028.
