The purpose of this analysis is to find undervalued, high-quality companies.
If you wait patiently, you will find undervalued stocks that are like pearls in the sand that discerning investors (mainly institutional investors and foreigners) will buy.
There are numerous financial analysis methods to utilize, but we have compressed them to only the essentials.
Future PER and dividend yield are used as the main tools to find undervalued, high-quality companies.
If the future PER and dividend yield calculated based on data found through news articles and public notices are high, it is a subject of analysis.
Without additional financial and non-financial risks, it becomes an attractive investment target.

The motto of this book is 'safe investment.'
Accordingly, safety nets were installed in multiple layers at high density.
We recommend investment analysis based on performance and dividends, and considering it for more than a day.
It is recommended to purchase up to three stocks in installments within the maximum annual salary.
We suggest conservative methods such as accompanying foreigners and institutions and investing in dividend stocks.
We also recommend split selling to help you let go of your excessive greed.
Investing in stocks is also about becoming happy.
The point is to be happy, so there's no need to feel stressed or anxious.
We recommend investing within three days of each month through performance- and dividend-based value investing, and developing investment habits that eliminate the need for regular market analysis.
In particular, on profitable days, I hope you turn off the stock market board and enjoy the sense of accomplishment and happiness.

The D-Day investment method is a safe investment method with little difficulty.
When it comes to stock investing, selling is more difficult than buying.
The D-Day investment method makes it easy to predict difficult sell-offs, making investment convenient and safe.
You only need to check the news for selling.
(Omitted) There was a time when the government was dedicated to the space industry.
They sent Koreans into space on Russian spacecraft and also launched Naro.
Although the launches continued to fail, the government's strong will allowed Naro to continue launching for several years.
Related stocks experienced repeated sharp rises and falls before and after the launch date.
Knowing the launch date of Naro, it was possible to invest on D-Day to coincide with the launch of Naro.

Management subjects are like soldiers of interest in the military.
The stock exchange is considering managing it as a stock with a risk of delisting, so there's no way that company will be in good shape.
In reality, there are many cases where a stock moves from being managed to being delisted.
(Omitted) If a KOSDAQ-listed company has operating losses for four consecutive years, it may be designated as a management stock, and if it has losses for five consecutive years, it may be subject to a substantive review of listing eligibility and may be delisted.

Among ETFs, there are products that incorporate derivatives elements.
Typically, leveraged ETFs have returns that are more than twice as volatile as regular ETFs.
That is, if the underlying index rises by 1%, the leveraged ETF rises by 2%, but conversely, if the underlying index falls by 1%, the leveraged ETF falls by 2%.
(Omitted) There is also a double inverse ETF (inverse 2x, also known as double inverse) that generates a return of more than 2% with a 1% decline.
It should be noted that high-risk ETFs are products that can result in the loss of the entire principal amount if the underlying index fluctuates.

Winix, a dehumidifier manufacturer, predicted record rainfall and explosive growth in the dehumidifier market in 2014 due to abnormal weather.
At the time, it was expected that Winix, the number one dehumidifier company, would monopolize the market.
Since we obtained estimates of the two companies' performance improvement and net income through newspaper articles, it was easy to calculate the future PER.
For both stocks, the future PER was less than 10 times the expected performance.
However, the short-term stock price graph was very steep, like a ski slope, as it had already reflected the performance estimates.
The sharp rise in the graph, which I would not have dared to buy if I were doing technical analysis, did not have a big influence on my buying decision.
I decided to boldly buy it, judging that it was undervalued compared to its future performance.
There were some areas of pressure after the purchase, so additional installment purchases were made.
The performance-based undervaluation prediction turned out to be accurate, resulting in a profitable stock that generated significant returns within six months.
