Losers led gainers by just less than a 2 to 1 margin in the RCR Wireless Stock Index for the week ended January 12. Notable losers were prepaid service providers Leap and MetroPCS. Investors continue to be concerned about the prepaid carriers ability to maintain solid profit margins as they faced with more competition. On the upside, Palm shares were up almost 13% for the week. Apparently investors were impressed with Palm’s showing at CES, with Wall Street analysts improving their ratings on Palm’s shares.
