The hottest potato that will determine the direction of the stock market this week is by far the earnings announcement of US Micron Technology. The report card that Micron, known as the wind vane of the global memory semiconductor industry, will release on the 24th will serve as a direct compass for the stock price trends of Samsung Electronics and SK Hynix, leading domestic semiconductor companies. Wall Street has already raised expectations, predicting that Micron's earnings per share (EPS) consensus will surge by more than 60% compared to the previous quarter. If Micron presents favorable guidance along with performance that exceeds market expectations, the concentration of supply and demand concentrated in the semiconductor industry will further intensify and become a powerful engine that lifts the entire index. On the other hand, we cannot rule out the possibility that volatility in the semiconductor sector will increase if profit-taking listings pour in, along with the assessment that performance expectations have already been reflected in stock prices.

What increases market tensions as much as semiconductor performance is the price index coupled with the monetary policy stance of the U.S. Federal Reserve (Fed). The May personal consumption expenditures (PCE) price index, scheduled to be released on the 25th, is the inflation data that the Federal Reserve considers most important, and is a key indicator that will determine the timing and extent of future interest rate cuts. The recent hawkish actions of Federal Reserve Chairman Kevin Warsh have shaken the market's confidence in forward guidance and made the market extremely sensitive to each economic indicator. If core PCE prices exceed expectations, it can be interpreted as a signal that inflationary pressures remain, putting downward pressure on the market. As a result, this PCE indicator will determine whether it will allay fears about prolonged high interest rates or become a catalyst for tightening the reins once again.

Amid the macroeconomic trends, major events that signal improvement in the domestic stock market are also waiting. What is attracting the most attention is the MSCI annual market classification review to be announced on the 23rd, and the keen interest is whether Korea will be listed as a country to watch for inclusion in the developed country index. Although incorporation will not take place immediately, just being listed as a country subject to observation can be a signal for mid- to long-term valuation rerating to resolve Korea's discount. In addition, political issues such as Prime Minister candidate Han Seong-sook's confirmation hearing, the June consumer trend survey, and events related to the domestic economy, such as the youth future savings plan promoted by the government, are expected to have a subtle impact on market sentiment. This week, where geopolitical risks, performance momentum, and policy variables are intertwined, requires investors' sophisticated strategies more than ever.

Market experts predict that toward the latter half of the general bull market, the compression of supply and demand toward leading stocks supported by performance will accelerate rather than the overall increase in the index. When applying the past average price-to-earnings ratio (PER), the dominant analysis is that KOSPI is open to 10,000 points, but this is a possible scenario under the premise that the fundamentals are operating normally. Individual companies' liquidity expansion strategies, such as expectations for SK Hynix's listing of American stock depository receipts (ADRs), will act as a positive factor to revitalize the stock market. However, there is always a possibility that the unstable situation in the Middle East surrounding the Strait of Hormuz will once again have a negative impact on oil prices and inflation, so investors should take a conservative yet agile response, focusing on stocks with confirmed performance visibility. In the end, this week's stock market will be a test where cool-headed judgment based on data rather than vague optimism will determine victory or defeat.
