[Thoughts from Yuki-kun @ Amateur Investor on the content]
Man, I analyzed it with big data, but stocks with large market capitalization and solid fundamentals are strong after all. Studying as an amateur and checking PER, ROE, EPS, and current ratios to select stocks is a great learning experience! It seems like it would be even more interesting if I deepened my chart patterns and technical analysis. Everyone, please set your own strategies according to your investment style, such as long-term, short-term, or dividend-focused. Let's enjoy asset management together!"
