Sienna Resources Inc. arrives at the end of April with a stock price down 16% on the month and a lending market that has lurched from near-full utilisation back to almost entirely open — a combination that captures just how volatile sentiment around this micro-cap miner has become.
The most striking feature of the past six weeks is not where borrowing demand stands today, but how dramatically it moved. Through mid-April, availability in the lending pool tightened to near-zero levels on multiple occasions — utilisation hit 94% on April 14 and 93% on April 16, meaning almost every share available to borrow had already been lent out. That is the tightest the borrow market has been all year, matching the 52-week utilisation high. Since then, conditions have reversed sharply. By April 28, utilisation was back down to just 5.6%, leaving the pool wide open relative to what was borrowed only a fortnight ago. Availability now reads at an estimated 8,667% of short interest — effectively unlimited supply relative to current demand. Cost to borrow, last reported on April 16 at 1.56%, had already fallen more than 80% from its February levels above 9%, confirming the squeeze pressure that built through early 2026 has largely unwound.
Short interest is genuinely small in absolute terms. At roughly 0.015% of the free float, there is no meaningful short thesis concentrated in the name. The 78% month-on-month rise in shares short sounds dramatic but the base is tiny — from around 3,600 shares in late March to 6,390 today, all measured in the thousands, not millions. With a market cap just under USD $2.7 million, even a modest institutional move dominates the tape. The ORTEX short score of 28 is low, reinforcing that shorts are not the defining force here.
Ownership data reflects the micro-cap reality. Only two institutional holders are on record: Palette Investment Management with a 1.2% stake (last updated June 2025) and Jason Gigliotti, the company's President, holding a further 0.27%. The most recent insider activity dates to February 20, when the President, CFO, and two directors all sold shares at CAD $0.40 — a price five times higher than today's close of CAD $0.08. Those sales followed same-day awards at zero cost, a routine compensation pattern, but the current share price sitting 80% below the February transaction price illustrates the severity of the de-rating. Net insider activity over the 90 days ending February 20 was nominally positive at 278,000 shares, but that figure is inflated by award grants rather than open-market purchases.
The closest available earnings event shows the stock fell 5.3% on the day and 10.5% over the following week, though the data set is thin and the share price then was materially higher. No future earnings date is currently confirmed. Among peer correlates, UCU on the TSXV dropped 10.7% on the week — in line with SIEN's own 5.9% slide — while FF on the TSX shed 7.6%, suggesting broad weakness in small Canadian mining names rather than a company-specific story.
What to watch: the next signal worth tracking is whether the borrow market tightens again from its current loose state, which — given how abruptly it moved in early April — would be an early read on renewed directional conviction in a name that has so far offered mostly volatility without volume.
