FNDA's Short Surge Fades as Borrow Stays Loose

The Schwab Fundamental U.S. Small Company ETF (FNDA) heads into the final week of June with one genuinely curious data point — a sharp build in short interest that has quietly started to unwind — against a backdrop that otherwise looks unremarkable for a passively managed small-cap fund.

The short interest story is the week's main angle, though the headline numbers require context. Short interest jumped roughly 135% over the past month, climbing from near-zero levels in late May to around 199,000 shares by June 23. That sounds dramatic. In percentage-of-float terms, however, it barely registers — 0.07% of the free float. This is characteristic of ETF mechanics rather than directional conviction: authorised participants regularly create and redeem short positions as part of arbitrage activity around net asset value. The month-long build followed a period in late May when short interest was essentially nil, just a few hundred shares. The past week has seen that position trim back by roughly 4%. Nothing here signals a structural short thesis against U.S. small caps.

The lending market confirms the lack of conviction. Availability is genuinely loose — 2.35 million shares remain available to borrow against the 199,000 currently short, giving an availability ratio above 1,000%. That figure was even higher earlier in the month, above 9,000%, before the short build began. Borrowing costs have drifted up modestly, reaching 2.49% — up about 7% on the week and 11% over the past month — but that remains a low absolute rate consistent with ordinary ETF lending dynamics. There is no squeeze pressure anywhere in this setup.

Options activity is effectively absent. The put/call ratio has been zero for the past several weeks. The 52-week high PCR was just 0.67, recorded once. FNDA simply does not attract meaningful derivatives activity, which is typical for a mid-sized passive ETF focused on fundamental weighting rather than a momentum or thematic story.

The ORTEX short score sits at 29.9, placing FNDA in the lower third of the short-interest universe — consistent with a fund where shorts play a structural arbitrage role rather than an express bearish one. The combined score of 29.7 tells a similar story. On price, the fund is off half a percent on the week and down 0.46% on Tuesday's close at $36.81, though it has recovered about 3% over the past month as small-cap value names caught a bid. Dividend history shows a $0.06 quarterly distribution announced in February 2026, with no earnings event on the calendar — consistent with a fund structure.

The data point worth tracking is whether the short interest build of the past month continues to unwind or stabilises at a new, higher baseline. For a fund with this structure, a persistent elevated short position relative to its own recent history is more likely a signal about ETF arbitrage flows and creation/redemption activity than about directional positioning in U.S. small caps.
