Aura Minerals Surges Into Earnings With Short Sellers Caught Offside

Short sellers are not the dominant story here, but the numbers are worth noting. Short interest has climbed about 47% over the past month to 5.8% of the free float — a meaningful jump that puts bears in a difficult position heading into a print that has already sent the stock sharply higher. Despite that build-up in positioned shorts, the borrow market is far from stressed: availability runs at 338%, meaning there are more than three shares available to lend for every share currently borrowed, and the cost to borrow has fallen 25% over the past week to just 0.58%. There is no squeeze mechanics pressure here — availability is actually at its loosest level of the past two weeks, easing from a tighter 274% reading in mid-July.

Options positioning shifted notably into Wednesday's close. The put/call ratio dropped to 0.88, below its 20-day average of 1.03 and roughly 0.7 standard deviations below that mean — suggesting traders rotated toward calls as the stock surged, rather than reaching for protection. That pivot in options sentiment aligns with the price action. Insider activity over the past 90 days complicates the picture: the COO and CFO were steady sellers through late June and early July, offloading a combined ~$6.5 million at prices around $62–$65. That selling happened near current price levels, which means those insiders exited at or below where the stock trades today.

On the ownership side, Capital Research added 3.5 million shares in the most recent reporting period, taking its stake to 6.1% — a substantial accumulation from a well-regarded institution. Van Eck, a natural holder of gold-sector names, added 1.6 million shares through July. Controlling shareholder Paulo de Brito holds 47.5% of shares and trimmed only marginally. The institutional flow looks constructive even as management-level insiders were reducing exposure.

Valuation is undemanding for a gold producer: the stock trades at roughly 6.1x trailing earnings and 4.1x EV/EBITDA, both of which have compressed modestly over the past 30 days as the earnings base improved faster than the share price had moved — until this week's rally. The Q2 print will test whether that copper and gold production momentum has translated into earnings that justify both the institutional accumulation and the sharp re-rating the market has just handed the stock.
