RPGL Borrow Market Tightens Fast as Stock Collapses

Republic Power Group Limited enters the week as one of the stranger setups on Nasdaq — a micro-cap that shed nearly two-thirds of its value in a single session, while its borrow market simultaneously tightened to its most constrained reading in months.

The price action alone demands attention. RPGL closed at $0.83 on May 8, down 63.7% on the day and off 50.6% across the week. The stock peaked near $10 earlier in the quarter, so the three-month chart captures a near-total unwind. That kind of velocity — a 47% monthly gain suddenly reversed by a one-day collapse — is the signature of a heavily promoted micro-cap losing momentum all at once.

The borrow market tells the most charged part of the story. Availability has collapsed to just 22%, meaning for every five shares already lent out, barely one remains available to borrow — a dramatic tightening from 604% availability at the start of the week. Cost to borrow has climbed to 281% annualised, up nearly 20% over the past seven days, and sits close to the highest sustained levels in the trailing 30-day window. The lending pool effectively went from wide-open to almost shut in the span of four trading sessions. Short interest as a percentage of free float is still modest at around 1.1%, but the direction is unambiguous — shares short have risen more than 800% over the past month, from near-zero in mid-April to roughly 488,000 shares by May 7. The ORTEX short score has moved to 61.2, its highest reading of the week.

The availability pattern here has a recognisable shape. In late April — April 22 to 24 — availability briefly collapsed to 6–10%, the borrow market choked, and SI spiked to over 4% of float before unwinding sharply as short sellers covered. That prior episode saw the stock fall and then whipsaw. The current tightening is arriving on the back of a much larger price decline, and availability at 22% is tighter than at any point in the intervening period.

Institutional ownership gives context for the thin market structure. Only three holders appear on the institutional register, with the largest — Hao Feng Ng — holding roughly 506,000 shares as of early April. A separate cluster of insider activity from March shows a main shareholder, Cetera Wealth Services, selling consistently across at least ten sessions between early and mid-March — offloading over 986,000 shares at prices ranging from $0.55 to $1.66. That selling pressure predated the current collapse but points to a float that was already losing support from one of its largest holders.

The last confirmed earnings event, in December 2025, produced a one-day move of -18% and a five-day follow-through of -41%. The next event is pencilled in for December 2026 — a long runway. With no near-term catalyst on the calendar, the stock's next moves are likely to be driven by short-side positioning and whatever residual float remains in active hands. Watch whether availability stabilises above 20% or tightens further toward the near-zero levels seen briefly in late April — that threshold has twice coincided with violent intraday moves in both directions.
