Samsung Electronics reports third-quarter results on Thursday, and an operating profit of KRW 100 trillion is said to be all but certain. Everyone already knows that number, so what happens to the stock after the release?
2026-10-06
The question is not KRW 100 trillion but KRW 110 trillion
The FnGuide consensus is operating profit of KRW 108.1 trillion and revenue of KRW 201.7 trillion (Money Today, 2026-10-05). Kiwoom Securities sees KRW 107 trillion and IBK Investment & Securities KRW 101.7 trillion (Money Today, 2026-09-23; CBC News, 2026-10). That means the market treats crossing KRW 100 trillion as nearly settled. So the crossing itself is unlikely to move the stock, and the line the market is watching is above consensus.
The report gave only the consensus figures and did not address why those numbers have drifted lower recently. The reason is a stronger won.
We lowered our USD/KRW assumption from 1,440 to 1,400. — Son Ik-jun, Eugene Investment & Securities (Korea JoongAng Daily, 2026-10)
Thirteen of 17 analysts put operating profit below KRW 110 trillion (Korea JoongAng Daily, 2026-10). Samsung Electronics has a large export share, so a stronger won reduces the won value of its dollar revenue. That is why profit estimates stay below expectations even though semiconductor exports set a record at $60.3 billion.
The fourth-quarter guidance will decide the stock
The results figure is already in the price, and there are two pieces of new information on release day.
- Commodity memory prices. Kiwoom Securities expects fourth-quarter commodity DRAM to rise only 3% and NAND 12% from the previous quarter (Korea JoongAng Daily, 2026-10). That means the pace of price increases is cooling.
- HBM. KB Securities estimates that 2027 HBM prices will rise more than 100% year over year (Kim Dong-won, Korea JoongAng Daily, 2026-10). If confirmation comes of how many times HBM4 mass-production revenue multiplies, it could mask the fourth-quarter slowdown.
Scenario branches
| Scenario | Condition | Share price direction |
|---|---|---|
| Beat | KRW 110 trillion or more, HBM4 revenue growth confirmed | Expectations are high, so the gain may be limited |
| In line | KRW 105-110 trillion, fourth-quarter guidance maintained | Catalyst exhausted. Attention shifts to macro variables |
| Miss | KRW 100-105 trillion, slowing commodity prices emphasized | If foreign selling overlaps, there is a risk of losing the 7,000 level |
The table is a judgment based on the evidence above and gives no probabilities.
Variables outside earnings
The KOSPI is barely above 7,000 at 7,003.74, and foreign investors net sold more than KRW 20 trillion over the past month (Seoul Economic Daily, 2026-10-06). The US 10-year in the 5.3% range also weighs on valuations. Even with good earnings, if foreign flows do not turn, the index could stay in a narrow range. The remaining buyback capacity is also shrinking. Samsung Electronics has about KRW 900 billion left and SK hynix has completed 76.24% (Seoul Economic Daily, 2026-10-06). That means support from buyback demand is weakening.
What investors should do
- Rather than adding exposure before the release to bet on expectations, it is better to wait until after the release, check the HBM4 language and the fourth-quarter guidance, and then act, because the asymmetry is more favorable.
- If you already hold the stock, plan in advance to trim part of the position into a rally if results beat consensus.
- The Oct. 9 Hangul Day closure means the reaction is concentrated on the 8th alone. Prepare for gap moves and do not buy or sell all at once.
