SCHG enters the final weeks of May with a curious split personality — short-side activity is rising fast while the broader ETF market pours money into the exact mega-cap growth names it holds.
The positioning story is all about magnitude, not direction. Short interest on SCHG climbed 60% over the past month to around 3.5 million shares, equal to roughly 0.22% of the float. The number has moved — up nearly 39% in a single session on May 19 — but it remains too small to carry any meaningful squeeze or crowding risk. Borrowing is cheap at 0.55% annualised, barely changed on the week, and availability is extraordinarily loose at over 1,380% of estimated short interest, meaning shares available to borrow are roughly 14 times the current short position. The ORTEX short score of 28 sits well below what would signal concern. In this context, the options market looks mildly more guarded: the put/call ratio ticked up to 0.275 on May 19, a little above its 20-day average of 0.261, but the z-score of 1.23 is far from alarming. At a 52-week low of 0.22 and high of 0.55, the current reading is roughly in the middle of its range and trending toward the call-heavy end. Options traders here are not hedging aggressively — they're largely positioned for continued gains.
The wider ETF flow picture gives that read more context. US equity funds pulled in a net $27.6 billion over the past week, with Information Technology ETFs leading the charge — a remarkable $11.5 billion in net inflows last week alone, the largest sectoral net flow by far. Over the past month, tech-sector ETFs have attracted over $119 billion net, dwarfing every other category. SCHG, which concentrates in exactly those large-cap growth and technology names, sits directly in the path of that flow. The fund has climbed 3.9% over the past month, even as the past week delivered a modest 0.5% retreat and Tuesday's session shaved another 0.9%. The monthly gain confirms the fund has been carried by the same current that's drawing the big ETF flows.
What bears watching from here is whether that technical position on short interest — rising fast but from a negligible base — reflects mechanical hedging ahead of potential index rebalancing, or a more deliberate bet against the tech rotation continuing. Given how abundant borrow supply is and how cheap it remains, there is no signal of pressure or stress in the lending market. The next session to watch is therefore less about who is shorting SCHG and more about whether the extraordinary pace of tech ETF inflows over the past month begins to moderate — because that, not the short book, is what moves a fund like this.
