" That was actor Jun Ji-hyun's own stock-investing rule, which she revealed on the YouTube channel DdeunDdeun on the 16th. Hearing her words, MC Yoo Jae-suk immediately marveled, saying, "There are many people around me who invest in stocks, but there are not many who set a target return and take profits in one clean move." At first glance, Jun Ji-hyun's investment rule seems simple and straightforward. But as Yoo Jae-suk noted, most individual investors cannot easily follow it.That is because it runs directly against human instinct. Why can't retail investors sell at their target price? The trap of the disposition effect It is not easy for people to go against instinct.
Many retail investors scoff at Jun Ji-hyun's investment philosophy with a dismissive "tch. " They know exactly why.
If I don't, it always ends up in the red later. If it turns negative, I wait a little.
It is not that they do not understand it; they simply admit that before being retail investors, they are human. In behavioral economics, this is called 'Disposition effect' .
If I don't, it always ends up in the red later. If it turns negative, I wait a little.It refers to the human tendency to sell winning stocks quickly while holding on to losing stocks for too long. Because people do not perceive gains and losses symmetrically, the pain of losing 100,000 won feels psychologically greater than the joy of making 100,000 won.
What is interesting is that Jun Ji-hyun's pattern of "taking profits at the target return and waiting when in the red" also looks like the behavior pattern behind the disposition effect. But there is a crucial difference.The disposition effect is problematic not because people sell too early, but because they sell based on emotion without a plan. By contrast, Jun Ji-hyun's approach is not driven by emotion; it is guided by rules."If it goes up a little more." The anchor of the peak etched into our minds There is another reason individual investors fail to sell even after a stock reaches the target price they set in advance.The moment the target is hit, greed kicks in and they quickly create a new target.
Someone who bought with a 100,000 won target may hold on when it reaches that level, saying it will go to 150,000 won.
If I don't, it always ends up in the red later. If it turns negative, I wait a little.
In many cases, once it reaches 150,000 won, they will change their mind again and think, "It will probably go to 200,000 won.
If I don't, it always ends up in the red later. If it turns negative, I wait a little." Another familiar concept in investing, 'Anchoring effect' , also comes into play.
The "peak" seen during a stock's rise can become a new reference point in the mind and distort judgment.2 million won.1 million won, investors still have a 100,000 won gain, but they may easily fall into the illusion that they have lost 100,000 won from the peak.Once they feel that they are losing money, selling becomes even harder.A system that erases emotion.
If I don't, it always ends up in the red later. If it turns negative, I wait a little.
How to reduce the psychological cost The other half of Jun Ji-hyun's rule is the part that says, "If it turns negative, wait a little.
If I don't, it always ends up in the red later. If it turns negative, I wait a little." What makes it different from being trapped by the disposition effect and blindly averaging down or leaving the stock alone is that there is a response scenario established before buying, functioning as a kind of system.In the end, the essence of Jun Ji-hyun's rule lies in a system that restrains greed in profitable periods and controls fear in losing periods would not be an exaggeration.Jun Ji-hyun's investment philosophy essentially reminds us that the core of investing is always a battle with one's own psychology.
Many individual investors, including this reporter, still get swept up by the order book when profits appear and fail to sell in time, then panic in a falling market and dump their holdings at the bottom.That is why Jun Ji-hyun's rule is worth revisiting: "Sell according to the rules you set in advance when you are in profit.Do not sell out of fear when you are in the red.
If I don't, it always ends up in the red later. If it turns negative, I wait a little.
" I do not want to become someone who keeps saying, "I should have bought it, I should have sold it, I should have held on." Yet every day, it feels like everyone else is doing well in stocks, real estate, and personal finance without me.The world of investing is difficult no matter how much you study, but if you want to receive [World of Retail Investors] comfortably and join in the applause of shared empathy, please subscribe to the reporter page.We are also waiting for tips from retail investors who have an investment story they would like to share.
