System Research: Short Sellers Retreat Ahead of May Earnings

System Research Co.,Ltd. heads into its May 8 earnings with one of the more striking short-covering stories in Japan's small-cap software space this spring.

Short interest tells the leading story here. SI peaked at 4.55% of free float in early April and has since been cut more than in half, falling to 1.90% as of April 29. That's a sustained, orderly unwind — not a one-day event — with roughly 307,000 shares covered over four weeks. The pace picked up noticeably this week: SI dropped from 2.0% to 1.90% in just two sessions, bringing it to its lowest level since before the March run-up.

The lending market reinforces how much the pressure has eased. Availability, which measures shares still available to borrow relative to those already lent out, has surged back above 1,500% — firmly in "loose" territory, meaning there are roughly fifteen times more shares available to borrow than are currently shorted. That's a sharp reversal from mid-April, when availability had compressed to around 700-900%, and from late March, when it sat as low as 460%. The cost to borrow data (last updated April 17) showed 2.14%, more than double its early-March level of around 0.76%. CTB had spiked as high as 4.45% in mid-March when the previous wave of short selling was at its most intense, before easing back. The current direction — short interest falling, availability loosening — suggests that wave has fully unwound.

The ORTEX short score also confirms the retreat. It stood at 45.9 in mid-April and has declined steadily every session since, reaching 35.2 on April 28. A score in the mid-thirties is unexceptional — it's no longer flagging elevated bearish conviction from the lending and positioning data.

Positioning, in sum, looks less charged than it did a month ago. The short score ranks in the 49th percentile of the universe, days-to-cover ranks in the 23rd, and utilization ranks in the 57th — a mix that suggests broadly neutral short positioning rather than any extreme leaning in either direction.

The ownership picture is dominated by insiders and a small cluster of institutional holders. FMR LLC holds just over 10% of shares, the largest single institutional bloc. Founder-adjacent names — including Toshiyuki Yamada at 9.6% — collectively hold a substantial slice of the float, leaving relatively few shares in active circulation. The most recent material insider transaction on record was Yamada's sale of 800,000 shares in September 2025, which reduced his stake; that data is now more than seven months old and should not be read as a current signal.

The earnings history provides modest context ahead of the May 8 print. The last four reported events showed one-day moves ranging from -1.6% to +3.7%, with five-day moves mostly negative: -4.4% and -4.1% in the two most recent quarters. The stock closed April 28 at ¥1,691, down about 2.4% on the week and 2.7% over the past month. Peer 9739 on TSE also slipped around 2.6% on the week, broadly consistent with the sector tone. 9629, a more volatile TSE peer, fell 17.3% on the week — a notable divergence that is worth monitoring as a read on sentiment toward Japan's smaller software names into results season.

What to watch is whether the short-covering impulse continues through May 8 or whether the earnings release draws fresh positioning in either direction — and whether the historically negative five-day post-earnings drift repeats in the current environment.
