Blackberry unaware of reasons behind surge in company's share price

Blackberry said it was not aware of any "material, undisclosed corporate developments" that might explain Monday's rapid climb in its stock price.

As of 1846 GMT, shares of the smartphone maker were climbing by 21.49% to reach CAD $21.49, having earlier jumped by over 30%

At the behest of Canada's Investment Industry Regulatory Organization, the artificial intelligence and cybersecurity specialist also said that there had been no "material change" in its business or affairs that had not already been publicly disclosed and which might explain the share price jump.
