Markets have felt pretty bumpy this year, and when things get choppy, investors tend to go hunting for a turnaround story they can believe in. Lately, one familiar name has popped back onto a lot of watchlists: BlackBerry Limited (TSX:BB)(NYSE:BB), the long-running Canadian tech company that many people still associate with its phone era.
The move has been hard to miss. Over the past month, BlackBerry shares have jumped more than 70%. That kind of surge naturally gets people talking, especially because it brings up an old question. Is BlackBerry drifting back into meme stock territory, with momentum traders and retail investors pushing the price around? It also matters that the stock has not been this high since February 2025, so there is a real sense of asking what changed. The big debate is whether this run is mostly hype, or whether the underlying business is finally starting to show steady progress.
One reason investors are paying attention is that the most recent results were not just a vague things are improving story. In early April, BlackBerry reported its fourth-quarter numbers for fiscal 2026, and the headline was a return to growth. Revenue rose 10% year over year to $156 million. For a company that has spent a lot of time restructuring and sharpening its focus, getting back to top-line growth is a meaningful signal. The cash picture looked better too. BlackBerry generated $45.6 million in operating cash flow, and it marked the eighth straight quarter where the bottom line improved. That does not guarantee a smooth ride from here, but it does explain why the market is taking the update seriously.
If you ask many bullish shareholders what they are really buying, they will point to QNX. This is BlackBerry’s software unit that shows up in a lot of embedded systems, especially in the auto world. In the latest quarter, QNX posted record revenue of $78.7 million, which was up 20% from a year earlier. For software investors, that is the kind of growth rate that can change sentiment quickly. QNX also reached the Rule of 40, a common yardstick that looks at the balance between growth and profitability. Hitting that benchmark tends to get noticed because it suggests a business is not growing at any cost, but still has enough momentum to expand.
Management is clearly trying to reshape the narrative. CEO John J. Giamatteo has said that, in his view, BlackBerry is no longer a company in transition. He is positioning it as a profitable business that is finding its growth rhythm again. Still, it is worth keeping expectations realistic. BlackBerry shares can be volatile, and big one-month jumps do not always hold up once the excitement fades. If you are watching this stock, it helps to stay focused on a few practical checkpoints, like whether revenue growth can continue, whether cash generation remains consistent, and whether QNX keeps delivering strong numbers. If those pieces stay in place, the rally could have room to continue. If they slip, the stock could cool off just as quickly.
