VFS heads into its September 18 earnings report with the borrow market tightening sharply — a development that has moved materially since the last preview four days ago.
The lending picture has deteriorated quickly. Availability has fallen to just 7.4% — meaning fewer than one share remains available for every thirteen already lent out — down from around 24% a week ago. That is a 69% tightening in availability over seven days, reversing the modest loosening that had developed through late August and early September. Cost to borrow remains elevated at 11.7%, broadly unchanged from the persistent 10–12% range that has held for most of the past six weeks. The 52-week low availability touched 0.03%, and the current reading is creeping back toward that extreme. For context, availability below 50% is already considered tight; at 7.4%, the lending pool is close to exhausted. Short interest itself remains negligible at just 0.11% of the float — so the expensive borrow reflects intense demand relative to a structurally thin pool of available shares, not a crowded structural short position. The ORTEX short score has climbed to 69.0, its highest point in the available history, reinforcing that the lending market signals are intensifying into the print.
Options positioning is notably calm by comparison. The put/call ratio of 0.51 sits almost exactly in line with its 20-day average, with a z-score near zero. There is no unusual demand for downside protection in the options market — a contrast with the stress visible in the borrow market. The stock itself closed at $3.13, up about 1.6% on the week but down 2.5% on the day and roughly flat over the past month. Analysts hold targets averaging around $5.75 — nearly double the current price — with Chardan Capital maintaining a Buy at $5.50 and Wedbush holding an Outperform at $6.00. Those targets have not moved in months, and the gap between price and consensus remains one of the defining features of this name.
The bull case rests on delivery momentum toward a 300,000-vehicle annual target, $2.6 billion in liquidity, and the potential for VinFast to capture EV market share as government mandates accelerate globally. Bears point to deeply negative margins — the EV/EBITDA multiple is running at -9.7x — heavy reliance on majority shareholder Vingroup for funding, and a track record of negative earnings reactions, with the two most recent prints delivering day-one declines of 1.6% and 5.3% respectively. The five-day reaction after the June print was essentially flat, but the broader trend of post-earnings softness gives bears a concrete historical pattern to point to. Ownership is highly concentrated: Vingroup holds 83.5% and founder Pham Nhat Vuong a further 14.3%, leaving a thin public float that partly explains why borrow costs stay elevated even with modest short interest in absolute terms.
Thursday's print is ultimately a test of whether VinFast can show any progress toward gross margin breakeven — the single data point most likely to determine whether the gap between the stock price and analyst targets starts to close, or widens further.
