* Many people may be curious about how I was able to make a lot of money through stock investment while running a hospital.
I will reveal the details in the text, but through a long period of trial and error, I was able to perfect my investment method, which is suitable for the situation where I have to see a doctor every day.
This might be a helpful story for professional investors.
After five years of investing in stocks, I went from being a bad credit debtor to the owner of a 34-pyeong apartment in Gangnam, Seoul, but it still doesn't feel real.
I never dreamed that my vague dream of owning a home would come true in just five years.
If someone like me, who was burdened with debt, had said five years ago, "I'm going to buy a 30-pyeong apartment in Gangnam, Seoul within five years!", they would have likely been called crazy.
Isn't it nearly impossible to buy an apartment in Gangnam worth billions of won without a loan?
But then something happened to me that I thought was impossible.

** Looking back, after I decided to invest in stocks, I think I tried to read a lot of classic books on stock investment and financial management that were familiar to the public.
For the first three years after I started investing, I read over 30 books a year, or nearly 100 books, whenever I had time.
And I would stop by the stock book section of the bookstore to see if there were any new books worth reading.
However, any book should resonate with me and be especially helpful in actual trading.
No matter how many books you read, it is a separate issue from being good at stock trading.
Still, reading books on stock investment, knowingly or unknowingly, influences our investment decisions and thinking.
Even these days, I consistently buy and read books on stock investment, thinking that it is like fertilizing my stock farm.

** I also tried many different things when I was a beginner.
I tried portfolio construction and experimented with short-term trading, closing price betting, and opening price betting, but the results were not very good.
So, I went through trial and error for about a year.
The trading method that best suited my lifestyle as a full-time worker was swing trading.
At first, I took a strategy of investing for a few days with short-term swings, but it was very stressful to do it while also receiving treatment.
So, I felt comfortable with swing investing, focusing on just one stock for a medium-term investment period of no more than one month and no more than six months, and the results were good.
That's why my pen name is Swing Trader.
My main occupation is a doctor.
I spend nearly 10 hours a day in the clinic meeting patients.
For a doctor to become obsessed with short-term trading is tantamount to suicide in stock investing.
You can't help but lose both rabbits: patients and stocks.

** Let's say someone does me a favor and gives me some good information, some advanced information.
If you believe that information and invest a large sum of money to make money, that's great, but if things go wrong and you lose money, you'll obviously blame that person.
I have had many such experiences and have observed them from the side.
So now I'm reluctant to recommend stocks to my acquaintances.
Isn't it human nature to blame others when things go well?
Like everyone else, I hate it when my life is swayed by what other people say.
I feel more comfortable with the thought that even if I fail, it will be because of my choice, and even if I prosper, it will be because of my choice.
When you're investing in stocks, you'll sometimes hear acquaintances say things like, "You know this! This stock will rise for this reason!"
When asked where the information came from, he said he heard it from a high-ranking official at a securities firm.
Was I truly such a great being that a high-ranking official at a securities firm would leak confidential information without compensation? --- From "Are there any good sources?"

** I already knew from the news that SK Bioscience was not producing flu vaccines, so it was nothing special, but the words kept ringing in my ears.
I know better than most people the capabilities of SK Bioscience, which produces flu vaccines, especially SkyCellflu.
This is because we directly participate in vaccination programs every year and administer vaccines to patients.
But it sounded strange to give up the stable revenue from flu production, which was like 'swimming with your feet on the ground'.
It was well known that SK Bioscience would not produce a flu vaccine in 2021.
I interpreted that piece of news that had already been made public as a declaration by the company that it would focus on producing a domestically produced coronavirus vaccine instead of a flu vaccine.

** No matter how attractive a stock is, there are things we must check.
Let me summarize and introduce a few of them.


Is there a risk of default?
Are there a lot of convertible bond (CB) issuances (are they suppressing stock prices and lowering convertible bond prices?: refixing)?
Are you obsessed with issuing stock options? (In this case, it is difficult to tell whether you are running a business or trying to make money with stocks.)
?Are there any issues related to inheritance?
Are insiders selling stock?

It is very important to remember the above.
It's good for your mental health to consider these companies as bad stocks, even if they seem attractive.
I don't even look at stocks like that.
Even if we inherit, let's inherit from a normal company.
If you are a reader who is not yet married, remember that you must meet someone of the opposite sex who is attractive and respectable enough to be willing to take responsibility for, in order to have a happy marriage.
In that sense, stocks are love.
Even if such a company is inherited, it provides at least a chance to escape with the principal someday.

---From “Standards for Stock Selection”

** Discernment cannot be acquired through study.
For example, if you look at just one candle chart, it is just a candle chart.
However, if you imagine the emotions of market participants through the minute charts that the charts show, the one-dimensional charts appear more three-dimensional.
The same goes for Hogachang.
I look at the hogachang and imagine what the participants' emotions are like.
Sometimes, when I am unsure whether a stock will sell or not, I am prepared to buy a few orders in a stock with a thin order book, and I even intentionally buy 6 or 10 orders in the order book and continue to buy recklessly to see if it goes up.
Then, you get the feeling that someone, whether it's the power behind the scenes or the biggest player in the industry, appears and gets angry and threatens, saying, "Get out, get out!"
This is a kind of game that calls itself a power test, and the interesting thing is that each main gun has a different personality.
Some guns are meticulous, some guns are fiery, and some guns are petty.
In this way, the nature of the main gun can be known by looking at how it is traded in the order book and how the order book is managed.
I look at the order book and charts to determine whether the main gun is smart or stupid, and if I feel that the trader is one step ahead of me, I don't react.
Even if I try to respond, I will inevitably fall for their tricks and lose my supplies because they are smarter than me.

** Looking at the long-term moving averages, the 5-day and 20-day lines are in reverse alignment, but the 60-day and 120-day lines are still in positive alignment.
Another feature of this chart is that the moving averages are clustered together.
What does it mean when moving averages converge? When moving averages converge, there is strong resistance from bottom to top, and strong support when they break through from top to bottom.
Because it is the average price that everyone knows, everyone wants to protect, and everyone wants to buy.
Although it is a result-oriented story, Fila Holdings saw a significant rise in the stock price in May and June due to the explosive growth in golf sales at its U.S. subsidiary Acushnet, despite the pandemic, and the moving averages changed from a partial reverse alignment to a positive alignment.
In stock investing, it's important to read moving averages, but it's also helpful to constantly imagine how the moving averages will change in the future.
