CBA — Champion Bear Resources Ltd. — is a micro-cap mining exploration stock trading at C$0.04 on the TSX Venture Exchange. The story this week is not price action. It is the near-vertical rise in short interest from a standing start.
Short positions have exploded from near-zero to roughly 28,000 shares in a matter of weeks. At the start of April, shares short numbered just 267 — a rounding error for almost any stock. By April 21 that figure had risen to 2,906. It then jumped to 17,406 by April 24, and reached 27,906 by April 28. That is a more than 100-fold increase over the month. In absolute terms the number remains tiny for any stock with a meaningful float. But the rate of change is extreme, and the directional shift is unambiguous: someone has decided, for the first time in a long time, that this stock is worth shorting.
The lending market has responded. Cost to borrow has climbed sharply, reaching 5.69% by April 28 — up from just 0.59% a week earlier. That is an almost tenfold increase in one week. For context, the cost sat at that same 0.59% floor for most of the past year. The spike is consistent with a sudden and unusual surge in demand for borrows on a name that normally sees almost no short-selling activity at all.
The ORTEX short score ranks in the 80th percentile relative to peers, reflecting the unusual nature of this positioning shift. The score itself, at 28.1, has been relatively stable over the week — the rank captures how rare this level of short-side activity is for a stock of this profile. No analyst coverage, no institutional data of note (the most recent holder data is nearly two years old and therefore not relied upon here), and no options market complicate the picture further. The stock's earnings history shows consistent 25% single-day moves on announcement dates — notable for a C$0.04 name, and the next event is scheduled for May 5.
The key question heading into that May 5 filing is whether the short-interest build is an informed bet against the announcement, or simply a mechanical artefact of thin float and low absolute share counts. With 27,906 shares short on what appears to be a very thinly traded name, even small changes in position size produce dramatic percentage moves. Watch whether the short count continues to grow before the event date — or reverses just as quickly as it appeared.
