It was the day Samsung Electronics announced its preliminary earnings for the second quarter. The company recorded 89.4 trillion won, the highest in its history! This figure even surpassed the operating profit record of Nvidia, the world's largest company by market capitalization. However, despite this monumental achievement, Samsung Electronics' stock price plunged 7% today, falling below the 300,000 won mark. Why is this happening? For novice investors like myself who are struggling to navigate the recent rollercoaster market, SBS YouTube channel <Discovery of Knowledge> met with economic commentator Yoon Ji-ho. The recording took place on the morning of July 7, 2026, while the stock price was in the midst of a sharp decline despite the announcement of Samsung's record earnings. On a day like today, one really wants to hold someone accountable for their investment, but I must remind myself first that the responsibility ultimately lies with the investor.
