Rumors spread on Monday that BlackBerry Limited (
BBRY) might be acquired by Apple Inc. (
AAPL), sending the stock price up over 6% in roughly 30 minutes. This rumor is almost certainly not true, as it does not match Apple’s strategy in the past, as the acquisition would be the most expensive in the company’s history.

The tech giant has been rather cautious with its cash hoard in the past. Furthermore, similar rumors have surrounded BlackBerry in the past. A rumor suggesting that Samsung would buy the company sent the stock price up 30%, but these gains were reversed when BlackBerry released a statement saying the rumors were false and no conversations had taken place between the two companies.
