[Investment Note] Samjeon-Nics Are Taking an Exam After Being Given the Answers

A market saying has been circulating among South Korean investors: buy in the morning when stocks open lower, then sell in the afternoon.

The idea draws on a pattern seen in recent trading. Even when investor sentiment weakens because of repeated warnings about an artificial-intelligence bubble and rising U.S. Treasury yields, funds from other institutional corporations often enter during the session.

Those inflows have frequently helped major indexes reduce their losses or rebound into positive territory. Among short-term traders, the pattern has begun to look like a practical formula for making a useful return.

The headline refers to Samsung Electronics and SK hynix as companies that appear to give investors the answers before they sit the test, framing the market pattern as unusually easy to read.
