While BlackBerry pulled out all the stops today with its debut of BlackBerry 10 phones and apps, investors weren’t enthusiastic, with the company’s stock closing down more than 12 percent today.

Formerly known as Research in Motion, BlackBerry introduced two new phones running BB10 — the touchscreen BlackBerry Z10 and the keyboard-toting BlackBerry Q10. It also announced a ton of high-profile apps like Facebook and Skype and named musician Alicia Keys as its new global creative director.

The company’s stock price has been all over the place in the past year as it has struggled to reinvent itself to better fight Apple, Samsung, and other big players. BlackBerry’s 52-week high is $16.62, while its 52-week low is $6.22.

At the end of trading today, BlackBerry’s stock ended down 12.2 percent to $13.75 per share.

To account for the change of its company name today, BlackBerry will change its ticker symbol on the Nasdaq stock exchange from “RIMM” to “BBRY” on Monday.
