According to statistics, the blue-chip stocks led by automobile, steel and finance rose in turn this year, which pushed the stock index to rebound sharply, with a cumulative increase of more than 2%. However, there was a great difference among individual stocks, with only 2% stocks rising more than the broader market, while more than 5% stocks fell instead of rising, even hitting a new low. The reason is that the funds in the whole market have intensified to a few large-cap blue-chip stocks. For example, on May 22, the total turnover of the top 2 stocks in Shenzhen and Shanghai was about 5.5 billion, while the total turnover in the two cities was 14.3 billion, that is to say, less than 4% of the stocks accounted for 4% of the total turnover in the two cities. Moreover, these stocks with the highest turnover were almost in the forefront of the day's gains, and most of them belonged to the recent mainstream sector.

This shows that the more active the stocks are, the easier it is to attract funds to join, which will make the stock price rise. The more depressed the transaction, the more the shareholders are encouraged to join the sale, which leads to the repeated decline of the stock price. From the experience of futures, the more varieties with huge trading volume, the more they can attract both long and short sides to join the fight, and thus the more market opportunities.

according to this phenomenon, we can focus on the top two stocks with daily turnover, and almost ignore other stocks. Most of these varieties with large trading volume have the characteristics of low stock price, low market earnings rate, large circulation and high dividends. The number of such stocks is less than 1%, but most of the opportunities in the market are concentrated. At present, there is still an upward trend, even if the quilt cover is short-lived, there is still a chance to untie it. Therefore, once the callback is made, it is the time to intervene. For example, Songshan of Shaogang once fell by nearly 3% in April, and it can not only recover lost ground but also hit a new high in the near future, which greatly simplifies the stock selection work. Instead of casting a net everywhere, it is better to seize the mainstream and make a key attack.

investors can pay special attention to the index stocks of Shanghai Stock Exchange 18 Index and Shenzhen Component Index. Last year, some new funds were set up specifically for these indexes, and these institutional investors also limited their stock selection to a small frame, which is worth learning from. Moreover, the Shenzhen Component Index has been the weakest index since 1997, and other indexes have reached new highs in 2, and the index has not been able to reach new highs. However, this year, the index has become the strongest index, reflecting that there are huge opportunities for index stocks. For non-mainstream stocks, even if there is intermittent market, because the market is difficult to grasp, it is a tributary and should not be easily involved. For example, the ST plate rebounded strongly after oversold this week, but continued to fall after a slight rebound. The overall downward trend makes holding such stocks contain great risks.

5% of the stocks are flames, and 95% of the stocks are seawater, which makes the operation mode based on tracking index irrelevant. Especially, the rise of a few index stocks conceals the fact that most stocks fall, which makes the risk of holding weak stocks even greater than a big bear market. Investors can make appropriate investment choices according to this new "28 Law".
