Stocks are closing higher, giving the market its fourth straight weekly gain, the AP reports. The gains Friday were led by phone companies and utilities, traditional safe-play stocks that have done far better than the rest of the market over the past year. Those high-dividend stocks have been appealing to investors hungry for income, particularly with the yields on US government bonds near historic lows of well under 2%. AT&T rose 1.4% and Exelon rose 2.6%. The Standard & Poor's 500 index rose 9 points, or 0.5%, to 2,175. The Dow Jones industrial average gained 53 points, or 0.3%, to 18,570. The Nasdaq composite increased 26 points, or 0.5%, to 5,100. (More Dow Jones stories.)
