[Stock in Focus] Hwasin Precision Motor Surges 13% Again Today…How Far Will Robot Parts Expectations Go?

Hwasin Precision Motor (126640) is making big moves again today. The current price is around ₩4,700, up +13.39% from yesterday. Given that it was trading in the ₩1,900 range back in early June, the stock has more than doubled in just over two months. For those who searched for this stock today, let me walk you through what we know so far and the risks involved.

Today's Surge Is About the Stock Itself, Not the Market

Yesterday on August 18th, the KOSDAQ index fell -3.52% under institutional selling pressure, retreating to the 834 level. Yet even as the broader market tumbled, Hwasin kept surging +13% — that tells us this move isn't about general market sentiment or macro factors, but rather pure company-specific catalysts. In fact, since early June, this stock has been marching to its own drum, regardless of index moves.

Why the Explosive Move — Boston Dynamics Robot Parts Expectations

It all started in early June. Reports emerged that engineers from Boston Dynamics — the robotics company under Hyundai Motor Group — made a private visit to Hwasin Precision Motor's headquarters in Yeongcheon, North Gyeongbuk. The stock hit the daily limit three days in a row. Hwasin supplies aluminum lower arms for Hyundai and Kia's EV platform (E-GMP), and the market caught wind that the company's aluminum lightweight forging technology could be used for mass-producing components for the humanoid robot "Atlas."

But here's what we need to keep in mind: so far we've only seen reports saying "they visited" and "feasibility was checked" — there's no official supply contract announcement from Boston Dynamics or Hyundai Motor Group yet. Today's additional surge shows this theme is still alive, but it doesn't appear to be based on any new official contract news.

What About Earnings — Q1 Returned to Profit With Double-Digit Operating Margin

Separate from the theme, the core business looks solid too. Provisional Q1 2026 results showed revenue of ₩485.3 billion and operating profit of ₩48.6 billion, for an operating margin of 10.0%. Compared to the full-year 2025 results (₩378.9 billion in revenue, ₩11.8 billion in operating profit, up +778.7% YoY), the profit level has clearly improved. The official PER shown by KRX is in the 57x range, but that's likely based on older earnings; recalculated on recent results, it comes down to around 14x. When reading these metrics, you need to account for this gap.

The Risks — The Robot Premium and Core Business Are Still Separate

First, robot component supply is not yet a confirmed contract. There's distance between due diligence and actual mass production participation. Second, with the stock already doubling since early June, profit-taking pressure from short-term traders is real. Third, it will take time for actual robot-related revenue to show up on the financial statements — meanwhile, the stock is moving on expectations alone. Fourth, KOSDAQ theme stocks tend to have huge daily swings, so short-term trading risk is substantial. Fifth, don't forget that the core auto parts business is cyclical and tied to OEM demand.

Key Factors to Watch Ahead

① Whether and when an official supply contract with Boston Dynamics is signed, ② Concrete Atlas mass production roadmap and supplier selection announcements, ③ Hyundai Motor Group's moves to expand robot component supply chains (scope of aluminum forging tech application), ④ Whether Q2 and beyond maintain Q1's double-digit operating margin, ⑤ Whether Hwasin Group's value-up initiatives (share buybacks, dividend expansion) continue. These five are the key checkpoints that will shape the stock's direction.

So Here's the Bottom Line

Hwasin Precision Motor is currently wearing two hats: "an auto parts stock with improving earnings" and "a robot theme stock." The 10% operating margin in Q1 signals solid core business improvement, and layered on top is a compelling robot supply story — which is why the stock is moving at an unusual clip. But given there's no official contract yet and the stock has more than doubled in two months, we have to soberly acknowledge that substantial expectations are already priced in. The real question is one thing alone: does "they visited" eventually become "they signed a contract"? Until that news breaks, the prudent approach is to treat this as a high-volatility theme stock.
