BHP heads into its May 3 production report with short sellers meaningfully rebuilding positions and the borrow market running at full stretch — a notable setup for a stock that has quietly recovered 12% over the past month.
The lending picture is the sharpest signal this week. Availability has tightened to effectively zero — the entire lending pool is lent out, a level that has been the norm for most of the past six weeks and matches the 52-week extreme. Cost to borrow has climbed 35% over the past seven days to 2.14% annually. That is not a punishing rate in absolute terms, but the direction of travel matters: borrowers are paying more for a stock where every available share is already out on loan. When availability is this tight, new short positions can only be established by pulling shares from existing lenders or stepping up to higher borrow costs — neither of which is straightforward in size.
Short interest itself is rebuilding after a dramatic unwind. Estimated short positions hit a high around 18.4 million shares in early April, then collapsed to roughly 14.6 million by mid-month — a drop of more than 20% in about a week, coinciding with a sharp bounce in the stock. Since April 20, shorts have been methodically adding back, with shares short climbing 8.4% on the week to 15.9 million. The ORTEX short score has edged up to 52.0, its highest reading in the recent history shown, but remains in moderate territory — this reads as a rebuilding, not a crowded, short book. Options positioning is similarly measured: the put/call ratio at 0.78 is just modestly above its 20-day average of 0.75, and the z-score of 0.67 suggests no unusual defensive hedging into the event.
The fundamental backdrop offers bulls and bears different footholds. The high-impact news this week centred on two items: BHP reportedly striking an iron ore deal with China in yuan rather than dollars — a structurally significant development for commodity trade flows — and a raised copper production outlook. Both play to BHP's positioning across two of the most macro-sensitive metal markets. Argus Research also raised its price target to $95 on April 29, a meaningful move given BHP trades at $78. That said, the broader analyst picture skews cautious: Bernstein's March note maintained a Market Perform with a $48 target, and Freedom Broker initiated at Hold with a $50 target in February. The gap between the most bullish and most conservative Street targets is wide enough to suggest genuine uncertainty about the commodity cycle. One valuation data point worth noting: the PE has expanded roughly 1.9 turns over the past month to 15.6x, tracking the stock's price recovery. EV/EBITDA has eased slightly to 13.2x. The dividend score ranks in the 92nd percentile — BHP's income credentials remain a structural support for long-only holders.
Institutional ownership is broad and stable. State Street, BlackRock, and Vanguard are the three largest holders, collectively above 20% of shares. Australian Super and sovereign-linked vehicles account for meaningful further strategic ownership. The institutional base provides a durable bid but also limits the float available for short sellers — context for why the borrow market runs this tight even with short interest well below extreme levels.
The earnings history for the February release shows the stock moved roughly 1.6% on the day and 8.5% over the five days following — relatively contained on the day, but with a sustained drift afterward. The May 3 production report is therefore less about the single-day reaction and more about what the copper outlook and any China iron ore commentary imply for the full-year earnings trajectory.
