The stock market performed well last week, touching fresh highs with no clear-cut catalysts aside from relatively strong earnings. Tech stocks outperformed blue chips, though small-cap stocks outperformed both. During Friday's session, the Dow Jones Industrial Average increased 28 points, or 0.09%. The S&P 500 was up 0.47%, and the Nasdaq Composite increased 0.50%. For the week, the DJIA climbed 310 points, or 1.00%, the S&P 500 climbed 1.23%, and the Nasdaq Composite led the way, climbing 1.73%. Year-to-date, the DJIA is up 2.78%, the S&P 500 is up 4.76%, and the Nasdaq Composite is up 9.37%.
