RIM shares fall as hopes for new BlackBerry fadeNovember 27, 2012: 1:53 PM ET
After a few moments in the sun, smartphone pioneer Research in Motion is again feeling the wrath of fickle investors.
Shares of the BlackBerry-maker fell 6% in afternoon trading Tuesday.
The advance has been driven in part by hopes that RIM, which has seen its share of the mobile device market decimated by Apple's (AAPL) iPhone, will finally release a new product.
RIM said earlier this month that its BlackBerry 10 operating system will debut on Jan. 30, a year after the company's next-generation smartphones and software were slated to go on sale.
But the optimism faded Tuesday as investors question whether the BlackBerry brand can recover following such a long hiatus in the dynamic market for smartphones.
On StockTwits, users pointed to a bearish research report from Morgan Stanley and data from Kantar Media that underscored BlackBerry's declining market share.
Another StockTwits user was not convinced RIM would even deliver on schedule.
But a few users were quick to rush to RIM's defense.
