BlackBerry Drops 8% in a Day as Insiders Sell and Borrowing Costs Double

The lending market carries no pressure for bears. Availability is running at roughly 492% of short interest, meaning there are nearly five shares available to borrow for every one already lent out. That is loose by any standard, well above the 52-week tightest reading of 264%. Short interest itself is only 3% of the free float, up about 12% over the past month in share terms but not at a level that signals heavy conviction from dedicated short sellers. Cost to borrow did jump sharply this week, rising from around 0.36% to 1.08%, nearly doubling over seven days. That is still cheap borrowing, below levels that typically constrain short positioning, but the move is abrupt enough to note. The overall picture from the lending market is that shorts are rebuilding modestly but face no squeeze risk in the current environment.

On the ownership register, Prem Watsa filed a Schedule 13D amendment in May, the 13D classification confirms activist intent on the register. His stake has fallen from 6.1% to 4.5% as last disclosed, crossing below the 5% threshold. Under SEC disclosure rules, a filer dropping below 5% may not file again, so the current position is unknown. Legal and General, the top institutional holder, added over 3.2 million shares through June and holds 6.5% of shares. T. Rowe Price filed as of September 30 showing a new position of nearly 33 million shares, one of the larger fresh institutional additions on the register. D. E. Shaw and Two Sigma also appear as new significant holders through June, both quantitative funds whose presence often reflects momentum and volatility screens rather than fundamental conviction.

The valuation picture is stretched relative to profitability. The EV/EBITDA multiple is 30.7x, down almost 6 points over the past 30 days as the multiple has compressed with the recent volatility. The PE ratio is 38.4x. The ORTEX short score is 37.5, squarely in the middle of the range and drifting slightly higher this week, consistent with a stock where short positioning is gradually building without reaching extreme territory. Factor scores are similarly mixed: sector rank at the 50th percentile, short score rank at 45, and an EV/EBIT factor score of just 15 out of 100, reflecting how expensive the stock looks on an earnings yield basis. The next earnings event is December 17, giving the market roughly ten weeks to reassess whether the guidance lift BlackBerry issued in its last print, including a revenue target of CAD 616 to 636 million and an 11-year high in free cash flow, justifies the current multiple after Wednesday's reset.

What to watch is whether the CAD 9.20 insider sale price, well below current levels even after the week's decline, acts as a reference point the market gravitates toward as the stock works through its post-rally consolidation into the December earnings date.
