RIO heads into its May 6 Q1 results riding a strong recovery — up 8% over the past month to $100.58 — while the short side has quietly dismantled.
Short sellers have been walking away from RIO for weeks. Estimated short interest has dropped 16% over the past month. The sharpest move came in mid-April, when shorts fell from roughly 12 million shares to around 10 million in a single session. The short score of 37.8 is modest and has barely moved, reflecting a market that sees little urgency to press the bear case. Borrow availability remains loose — cost to borrow is just 0.41% annually, and while that rate has risen 66% over the past week, the absolute level is still negligible. That combination points to a lending market with no squeeze dynamic in play.
Options positioning is close to neutral. The put/call ratio of 0.91 tracks almost exactly its 20-day mean of 0.92, with a z-score near zero. There is no material hedging activity in front of the print. The 52-week range on the PCR runs from 0.60 to 1.08, putting the current reading firmly in the middle of its distribution. Options markets are neither bracing for a sell-off nor making an aggressive directional bet.
The debate heading into the print has a clear fault line. The bull case rests on a meaningful re-rating in earnings expectations — the 12-month forward EPS estimate ranks in the 79th percentile for year-on-year growth across the universe, and the dividend score sits in the 92nd percentile, supported by a forward yield above 5.5%. The stock trades at a P/E of around 11.6x and EV/EBITDA of roughly 6.2x, both undemanding for a $172 billion mining major generating approximately $19.6 billion in operating cash flow annually. Bernstein nudged its target to $83.50 on April 27 while keeping an Outperform rating. The bear case is anchored by the Street's current average price target of $100.44 — essentially flat to the current price, meaning the analyst consensus implies no near-term upside from here. JP Morgan downgraded to Neutral in March, and Barclays moved to Equal-Weight in February, both reflecting concern that the stock's recent recovery has already done the work. The mean target also sits well below the prevailing share price on several broker models, suggesting the rally has outpaced fundamental revisions.
Institutional ownership data shows notable accumulation: BlackRock added 27 million shares in the most recent reporting period, and State Street added 18 million. FMR (Fidelity) added over 10 million. These are material inflows from three of the world's largest asset managers, and they arrived as the stock was still recovering from earlier weakness — now up 26% year-to-date.
Past earnings reactions have been mild. The February 2026 print produced a 1-day move of just +1.4%. The most recent event on April 30 moved the stock +4.2%, though that appears tied to an interim announcement rather than a standard quarterly update. The pattern suggests RIO is not a stock that routinely delivers outsized single-day swings on results.
The May 6 print will test whether the commodity-price recovery embedded in the stock's year-to-date rally translates into revised earnings guidance — or whether the analyst consensus, parked at roughly the current price, has already priced the good news in.
