JL0213 : Today's biggest gain is that I realized the importance of controlling positions. When the stock market in 2022 was good, I bought many stocks and put them in 2023, there was a problem. Many small, growing stocks accounted for heavy positions, leading to heavy losses. Plus, there wasn't that much time to track them one by one, so in the second half of the year, I began to adjust the position ratio, reduce the proportion of growth stocks, and increase the proportion of people in index funds. Although the profit was less, it took less time than before, which is more in line with my current actual situation.
