On the U.S.-Iran end-of-war agreement and foreign investors’ net buying for a third straight trading day, 코스피 rose +2.11% to 8,726.60, reclaiming the 8700 line. By contrast, 코스닥 fell -1.48% as buying was concentrated in large caps.

코스피 closed at 8,726.60. It rose 180.62 points, or 2.11%, from the previous trading day. The intraday high was 8,753.82(+2.43%). 코스닥 closed at 1,018.68, down 15.35 points, or 1.48%. The two markets diverged. The forces lifting the index were semiconductor large caps such as Samsung Electronics and SK Hynix, along with construction and financial stocks. 코스닥 was held back as machinery/equipment and chemicals declined.

In 코스피, foreigners led the rise with net buying of about 1조5,339억원. Foreign buying continued for three straight trading days for the first time in roughly two months, and cumulative buying over these three days was tallied at about 4조8,000억원. Media tallies differ, with institutions at about 7,000억~8,500억원 net buying and individuals at about 2조1,845억~2조3,290억원 net selling. Some outlets reported the foreign and institutional figures in reverse, listing institutions as the largest buyer in the 1조5,000억원 range. Many headlines saw the move as led by foreigners.

In 코스닥, individuals bought about 7,839억원, while foreigners sold -3,189억원 and institutions sold -4,628억원. As money crowded into 코스피 large caps, 코스닥 was left behind.

코스피 strength: construction +7.03%, metals +4.90%, financials +2.71%. Construction continued to draw expectations for Middle East reconstruction, while financial stocks set new intraday highs.

코스피 weakness: electric/gas -3.28%, IT services -1.66%, telecom -1.45%. Profit-taking emerged in power equipment and power-related stocks, which had been strong in recent days.

코스닥 strength: construction +2.36%, general services +1.67%, metals +1.54%.

코스닥 weakness: machinery/equipment -5.09%, chemicals -2.56%, non-metals -2.55%. The steep drop in 코스닥 machinery/equipment deepened the index decline.

Samsung Electronics rose 1.78% to 343,000원. SK Hynix rose 4.11% to 2,382,000원, leading semiconductor strength. Foreign investors focused their buying on Samsung Electronics and SK Hynix over the past three days. Leading financial stocks renewed record highs.

대신증권(media citation): It raised its 코스피 target index by more than 30%, from 8,800 to 11,500, citing "a sharp increase in earnings estimates centered on semiconductors and the possibility of valuation normalization." It viewed late August as an inflection point. This aligns with today’s flow, in which semiconductor large caps lifted the index.

SK증권(media citation): It presented a Samsung Electronics target price of 61만원 and forecast "a replay of a rising market driven by upward revisions to memory profit estimates." This explains the strength of SK Hynix +4.11% and Samsung Electronics +1.78%.

삼성증권(media citation): It sharply raised its Samsung Electronics target price to 50만원. It saw the recovery in the memory cycle as the basis for foreign buying.

이투데이 roundup(media citation): It viewed the market as testing whether it can break through the previous high, as end-of-war expectations overlapped with expectations for 2분기 earnings.

Common ground: Views converge that the U.S.-Iran end-of-war agreement and oil-price stability revived risk appetite, while expectations for semiconductor earnings are the main basis for the return of foreign investors.

Difference of views: 대신증권 saw large room for further medium- to long-term gains, while other views were more cautious about short-term volatility from the FOMC and profit-taking near the previous high.

Tomorrow’s link: The next points to check are whether foreign buying continues for a fourth day and whether the neglect of 코스닥 eases.
