According to Sigmarange real-time data, as of the close of the South Korean KOSPI index on the 28th, foreign investors net bought 821 billion won, with institutional investors net buying 963 billion won; retail investors, on the other hand, net sold 1.81 trillion won.
1. Foreign buying is a positive signal, but its sustainability remains to be seen. Foreign buying in large South Korean semiconductor stocks helps drive the index rebound. If net buying continues for several consecutive trading days, the credibility of the rebound will be higher.
2. Simultaneous institutional buying strengthens the financial foundation for the rise. This is more noteworthy than simply relying on individual investors chasing the rally. However, institutional buying may also include index adjustments, algorithmic trading, or short-term trading, and cannot be directly equated with long-term optimism.
3. Large-scale retail selling may reflect profit-taking or risk control. In a bull market, some investors will sell during rebounds. Net selling data alone cannot determine whether they are cutting losses, realizing profits, or reinvesting in other assets.
