BlackBerry (BB.TO) shares fell on June 9 following a period of high volatility. The stock recently surged from $6 to a one-year high of over $10. Retail investor interest and social media momentum drove the rally throughout late May and early June.

Significant selling pressure and profit-taking triggered the recent downturn. The decline occurred despite management announcing that the company's business turnaround is now complete. Executives stated at a recent conference that BlackBerry has entered a new growth phase.

Management highlighted strong prospects for the QNX software platform. The platform targets expansion within the automotive and robotics sectors.
