Bank of South Carolina Corporation has an unusual tension running through its lending data this week. Short interest is tiny in absolute terms but has more than doubled in a month — and the cost to borrow has held stubbornly elevated throughout.
The short-positioning story is the clearest starting point, even if the absolute level stays modest. Short interest as a percentage of free float is just 0.07% — so this is emphatically not a crowded short. But the directional move is hard to ignore. Shares short have risen 144% over the past month and nearly 74% on the week alone, reaching roughly 3,790 shares as of April 28. For a thinly traded OTC community bank, even small changes in absolute short positions translate into large percentage swings. The ORTEX short score has drifted higher through the week, closing at 45.0 on April 28 from 42.1 a fortnight ago — not extreme, but moving in one direction.
The more interesting signal is what the lending market is charging. Cost to borrow has climbed to 66.9% annualised — up 23% over the past month and near the high end of its recent range. For context, borrowing costs were closer to 47% in late February. That kind of premium for such a small, illiquid float is striking. It suggests the handful of short sellers active here are competing for a very limited pool of lendable shares. Availability, however, reads in a more relaxed zone — the borrow pool has not collapsed, and the overall utilisation of available shares is only around 10%, well below the 52-week peak of 33%. That divergence — high cost, but not constrained availability — points to a structurally thin and specialised lending market rather than an acute squeeze dynamic.
The ownership picture adds colour. The top institutional holders are almost entirely company insiders and executives. Hugh Lane controls just over 13% of shares. Charles Lane holds roughly 5.3%. The Bank's own employee stock ownership plan accounts for another 5.4%. With that much stock locked up in insider and ESOP hands, the free float is extremely narrow, which mechanically inflates borrow costs even when only a handful of positions are active. Insider trading data in the snapshot is stale — the most recent trades on record date to September 2023, when the CEO and several directors purchased shares at prices around $10. That is too old to inform the current setup; the stock now trades at $16.
On the Street, analyst coverage and formal valuation data are absent from the snapshot, which is typical for a micro-cap OTC name of this size. The factor score for the short-score rank sits in the 13th percentile, meaning BKSC ranks relatively low on overall short-side pressure versus its regional-bank peers — consistent with the tiny float percentage. The sector score sits at the 50th percentile, broadly neutral. Dividend data is stale (last recorded dividend was mid-2022), so no income angle can be confirmed from available data.
Earnings reaction history from the most recent quarters shows muted moves. The April 17 print produced a 0.24% one-day move and a 0.88% five-day drift. The April 14 event moved the stock 1.6% on the day. Neither reading suggests the market treats BKSC earnings as a volatility catalyst — consistent with the thin trading volumes and concentrated ownership base that tend to dampen price swings.
The setup to watch is whether the cost-to-borrow trajectory continues its month-long rise or begins to normalise. With short interest still growing as a share count but staying negligible as a float percentage, and borrow costs elevated relative to the actual demand picture, the lending dynamic here says more about structural illiquidity than about any developing conviction short thesis.
