The ostrich effect: cognitive avoidance driven by fear With the domestic market stuck in a harsh cycle of repeated downside pressure instead of the expected rally in leading stocks, some retail investors have followed A’s example and deliberately cut themselves off from information in order to endure the turmoil.Instead of checking stock prices, they are sharing half-joking, half-serious coping methods such as escaping into mobile games or casual games that do not require data. In behavioral economics, this is called "the ostrich effect" .It is the instinct to reduce psychological anxiety by avoiding threatening information. The term comes from the myth that ostriches bury their heads in the ground when they sense danger.What is interesting is that this avoidance is not always harmful. Nobel Prize-winning economist Richard Thaler explained this psychology through the concept of "Myopic Loss Aversion (MLA)" .He argued that the more often investors check their portfolios, the more sensitive they become to losses, making them more likely to make irrational selling decisions. .
This is the result of two cognitive biases working together: loss aversion, which makes people far more sensitive to losses than gains, and myopic thinking, which focuses on immediate changes rather than long-term perspective. In fact, the more often retail investors check their accounts each day, the more exposed they are to prices that swing like a roller coaster all day long.That is why even small moves can shake emotions and lead to impulsive trades and bigger losses."Buy More When It’s Cheap" — Brokerage firms raise target prices even in a falling market Despite the wild swings, securities firms remain upbeat.Some say the market is not suffering a fundamental breakdown, but merely going through a short-term correction, and that investors should use the decline as a buying opportunity.In fact, brokerage analysts have been raising target prices for leading stocks such as Samsung Electronics and SK hynix one after another, saying there is still room for further gains.
As memory chip prices continue to rise and the strong won adds another tailwind, the brokerage view is that these stocks will post even stronger earnings than expected this year.
