Weak results from several U.S. companies helped tug the stock market down slightly, putting major indexes on course for their first weekly loss this month. Many traders are also looking ahead to a packed schedule of events next week, including a Federal Reserve meeting and the government's monthly employment report. It is not a good day to be Zynga, or one of its investors if you held stock in the firm. Following a decidedly negative earnings report, investors have unloaded the firm?s shares, sending them down around 15 percent in regular trading. That loss comes after Zynga?s stock price rose in the wake of a very strong quarterly performance by Facebook. Amazon.com Inc shares hit a record after quarterly results increased optimism about the Internet retailer's U.S. business.
