About this theme

Iron ore is the largest single earnings exposure on the ASX and the most direct listed bet on Chinese construction. The majors are low-cost enough to stay profitable through most of the cycle, so shorting them is a macro position — a view on Chinese steel output, on new Guinean supply arriving, or on the discount applied to lower-grade product. The juniors are a different trade entirely: their margins are thin, their shipping and haulage costs are fixed, and a modest fall in the benchmark price can erase the spread between cost and revenue. Short interest in the majors therefore tends to be small in percentage terms but enormous in dollars, while the juniors show high percentage short interest on much smaller registers. Days-to-cover, not short percentage, is the meaningful comparison across this theme.

Short positions come from official ASIC short position reports (published with a T+4 trading-day delay) joined with daily price and volume data. The chart averages the constituents reporting in each week and shades the range between the least and most shorted of them; a member with no data that week is absent from the average rather than counted as zero.
