At the beginning, the granularity research is coarse, it doesn't matter, and it is slowly eliminated. For example, you can screen by industry, then remove some according to business model, and then remove some according to assets and liabilities, etc. In each round of screening, only the best ones are retained and the poor ones are removed.In the stock market, many people have greedy ideas. Especially, when their investment logic is not particularly clear, many stocks will be bought if they are grasped correctly. Buying and buying, I found that my position was full, but a single stock only had a little position.For this great goal, keep fighting.
Stock selection is to keep going through the sieve, from big holes to small holes, from coarse mesh to fine mesh, over and over again. Until the finest and highest quality stocks are screened out.Even if there is still some money, which one do you add in the face of so many positions? If you are really given a chance to increase your position by a big drop, you can't achieve the purpose of spreading the cost at all with what little money you have left. Don't say it doesn't make sense to reduce the cost of the whole account, even for the stock you added, it doesn't help much.In the early stage of investment, few but fine are passive and need your control. Although you don't know what's right yet, you already know what's wrong, so it will be hard to control your behavior with willpower, which is certain and insurmountable.
Some people will ask, how much is less? Personally, if your capital does not exceed 1 million and you hold up to 5 or 6 stocks at the same time, that's enough. Even if you average the score, each stock will have nearly 200,000 funds, and 20% of the positions will be enough, regardless of the profit value of a single stock or the contribution to the portfolio.In the early stage of investment, few but fine are passive and need your control. Although you don't know what's right yet, you already know what's wrong, so it will be hard to control your behavior with willpower, which is certain and insurmountable.The logic of profiteering is less but better.
