What caused the KOSPI to rise on Monday, November 2, 2026? The key trends observed on this day were net buying by institutional investors, which reversed the sharp decline early in the session , and strong October export and semiconductor earnings announced the previous day . While these two factors are the leading reasons for the rebound, it has not been proven exactly how much each contributed to the index's rise. One must distinguish between the fact that the market reversed its course after starting with weakness in U.S. tech stocks and the market's interpretation regarding the cause of that reversal.
Time of figure verification: The provided Yahoo Finance delayed quote indicates that the KOSPI on November 2nd is 5,859.08 points . This figure is 128.34 points (+2.24%) higher than the 5,730.74 points recorded on October 30th, the previous valid trading day. The observation time is 3:32:20 PM on November 2, 2026, Korean Standard Time (KST, UTC+09:00) , which corresponds to 06:32:20 UTC on the same day . This is distinct from the 3:30 PM KST (06:30 UTC) standard time for the close of regular trading. As delayed update times and daily figures vary by data provider, a separate comparison is required between the Korea Exchange's confirmed closing price and the final supply and demand by investor at market close. The 5,859.08 points shown below is a provided observation value and does not imply an independently verified confirmed closing price by the exchange.
| item | Confirmed details and standards | How to read |
|---|---|---|
| Comparison criteria | KOSPI 5,730.74 points on October 30 | The closing price of the previous trading day, the starting point for calculating the daily rate of change. |
| Delayed quotes provided on November 2 | 5,859.08 points, +128.34 points (+2.24%) | 15:32:20 KST observation value, distinguished from the confirmed closing price on the exchange |
| November 2nd opening price | 5,637.77 points, down about -1.62% from the previous trading day | Opening lower reflecting weakness in the US market |
| November 2nd early trading low | 5,616.50 points, down about -1.99% from the previous trading day | Showing the extent of the upward reversal after the morning decline |
| Confirmed intraday supply and demand | As of 12:32 KST, institutions net bought approximately 878.8 billion KRW, while individuals and foreigners net sold approximately 766.2 billion KRW and 370.8 billion KRW, respectively. | This is an intraday tally and does not represent the confirmed supply and demand at market close. |
The opening price and the early low can be confirmed in the market quotes and reports for the same date. As the index turned positive after falling to the high 1% range in the morning, the characteristic of November 2nd lies in a strong retracement following a downward start , rather than a simple rise . However, compared to the closing price of 5,937.66 points on October 29, it remains low based on the delayed quotes above. It is difficult to conclude that this one-day rebound marks the complete end of the recent correction.
The most directly observed change is the buying force . According to intraday reports on November 2 citing data from the Korea Exchange, institutions were net buyers at 9:23 AM, while foreigners and individuals were net sellers. Subsequently, institutional buying continued at 12:32 PM, and the KOSPI recovered to 5,855.52 points (+2.18%). Therefore, explaining the rebound on that day by stating that "foreigners returned and pulled the market up" does not align with the supply and demand at that time.
Institutional investors include various types of investors, such as financial investment firms and pension funds. Adding the net purchase amount of pension funds back to the total net purchase of institutions can result in double counting. Furthermore, intraday net purchases merely indicate the relative flow of orders and do not directly prove which macroeconomic news prompted a specific investor to buy. The observation that institutional buying supported the rally and the estimation regarding the specific reasons behind the purchases must be interpreted separately.
On November 1, the previous day, the Ministry of Trade, Industry and Energy announced the export and import trends for October 2026. According to official preliminary figures, total exports in October reached $115.28 billion, a 93.7% increase compared to the same month last year , while semiconductor exports totaled $56.44 billion, a 259.4% increase . The trade balance recorded a surplus of $42.5 billion. October exports exceeded $110 billion for the second consecutive month following September, and 18 out of the top 20 major export items showed an increase.
This data is important to investors evaluating corporate performance because the intensity of semiconductor demand is reflected in actual customs clearance figures. While the increase in exports could potentially lead to upward revisions in subsequent revenue and profit estimates, this does not mean that the price rise of all semiconductor stocks on this day was determined solely by the export announcement. In particular, the year-over-year growth rate is influenced by the difference between the figures of the base year and the number of working days. The working-day-adjusted daily average export growth rate presented by the Ministry of Trade, Industry and Energy is 76% , which needs to be examined alongside the simple annual growth rate.
Samsung Electronics announced its third-quarter 2026 results on October 29, reporting consolidated revenue of 195.3 trillion won and an operating profit of 107.4 trillion won. The company attributed these results to strong performance in the memory business and expanded supply of High Bandwidth Memory (HBM). SK Hynix presented third-quarter results on October 28 , reporting revenue of 104.6155 trillion won and an operating profit of 83.3338 trillion won. Since both companies released their own data, the basis for these figures is higher than market rumors.
These earnings are a confirmed fact demonstrating the profit base of the domestic semiconductor industry . However, it is impossible to calculate, solely based on supply and demand and price information, how much of the already announced earnings was newly reflected in the stock prices on November 2. Intraday reports also detected signs of recovery in the share prices of SK Hynix and Samsung Electronics following weakness in the morning. It is also important to note that since the index is calculated using a market capitalization-weighted method, the rebound of large-cap stocks has a relatively significant impact on the index.
It is also inaccurate to view this as a market where only semiconductors rose. As of 12:32 PM, intraday tallies showed gains across various sectors, including construction, transportation equipment and parts, machinery and equipment, and metals. In particular, strength was confirmed in some stocks related to shipbuilding and power equipment. However, there is no basis to attribute the day's rise in these sectors to a single government announcement or a single order disclosure.
As of the morning of November 2, the confirmed supply and demand showed a simultaneous presence of net buying by institutions and net selling by foreigners. According to Yonhap Infomax's foreign exchange market report on November 2, the dollar-won exchange rate stood at 1,341.10 won at 11:15 AM, up 6.80 won from the previous day's closing price of 1,334.30 won in the Seoul foreign exchange market. A rise in the dollar-won exchange rate signifies a weakening of the won. This figure is also based on morning observations and should not be cited as the final exchange rate for the day.
Foreign investors' stock selling and the weakening of the Korean won are worth observing together when assessing overseas investors' risk appetite. However, the mere fact that the two occurred at the same time does not mean that one is the sole cause of the other. Even if the Korean stock market has risen, differences in investment performance for foreign investors may arise due to exchange rate fluctuations.
On the previous U.S. trading day, concerns regarding the profitability of large-scale artificial intelligence (AI) investments by technology companies shook the market. The decline in U.S. tech stocks was reported as the background for the KOSPI opening lower on November 2. Domestically, since the KOSPI rebounded on November 2 after falling 3.48% on October 30, the rise on that day can be viewed in the context of an inflow of buying interest to offset the recent decline. This is a possible market interpretation and does not imply that it is the result of confirmed forced liquidation, short buybacks, or specific policy decisions.
The next regular domestic trading day is November 3, 2026 (Tue) . The Korea Exchange's standard regular trading hours are from 9:00 AM to 3:30 PM Korean Standard Time (KST, UTC+09:00). The outlook below is a conditional check framework , not a target price or probability prediction .
| scenario | Required confirmation signal | Points to note when interpreting |
|---|---|---|
| Upward extension | Large-cap semiconductor stocks maintain strength, institutional buying continues, rising sectors expand, exchange rate stability | A trend reversal cannot be confirmed based on a single day's rebound. |
| Repeated fluctuations and mixed trends | Earnings expectations and concerns over overseas tech stocks are at odds, and the intensity of institutional buying is slowing. | Even amidst sideways index movement, performance by sector can vary significantly. |
| Give back gains | Further weakness in U.S. tech stocks, increased selling by foreign investors, deepening depreciation of the Won, and a pullback in leading semiconductor stocks. | A decline cannot be predicted based on a single individual condition. |
In summary, the KOSPI rebound on November 2 is highly explanatory when considering the intraday buying dominance of institutional investors combined with sound fundamental conditions for semiconductors and exports. However, net selling by foreign investors and exchange rate pressures remain, and risks related to U.S. tech stocks have not been confirmed to have been resolved. On the next trading day, rather than simply following the previous day's gains, it is more useful to check the confirmed closing price, supply and demand by investor type, earnings outlook following exports, and scheduled inflation and economic indicators in that order.
