Click chart to track BlackBerry maker Research in Motion's stock.
NEW YORK (CNNMoney) -- A disappointing earnings report and grim guidance from BlackBerry maker Research in Motion prompted plenty of chatter about the increasingly competitive smartphone market on StockTwits.
Shares of RIM (RIMM) fell 22% Friday, a day after the company delivered disappointing BlackBerry and tablet sales, and cut its full-year profit forecast by 30%. The company also announced layoff plans.
RIM shares have been under pressure as Apple (AAPL, Fortune 500) and Google (GOOG, Fortune 500) gain market share with their mobile devices. Microsoft (MSFT, Fortune 500) and Nokia (NOK) are also major competitors.
There was also a lot of chatter about the dollar's decline against the euro Friday, after German Chancellor Angela Merkel and French President Nicolas Sarkozy said they had agreed on a structure for a Greek bailout package that would include voluntary support from private investors.
Earlier this week, the dollar rallied almost 2% against the European currency amid concern about a Greek debt default.
That's giving StockTwits users plenty to tweet about:
ryan_baum: The beginning of the end $RIMM. The next Palm...who will acquire you?
Matt_SF: Ironic how fast the market evolves: 5 years ago $RIMM was IT, now it's chopped liver thx to $AAPL & $GOOG.
shragoporter: Is $RIMM the new $NOK???...$MSFT should just swallow up $NOK.
Techinsidr: When your revenues aren't growing, you need to resort to other levers to regain profitability. Cutting HC makes sense for $RIMM.
johnjhardy: So Merkel backs down and we can all pretend that everything is going to be okay again....for a day or a week or a month...#forex $EURUSD $$
tag_ur_pregnant: Euro/Greece fears; the bark was worse than the bite. $EURUSD couldn't even make a new low relative to May 30th. Comical.
sparrowhawks: $EURUSD Look at everybody bearish of the $, if there's going to be a surprise it's not going to be to the downside.
