Main force is an important concept in the stock market, usually referring to investors or institutions that have significant influence on market trends during a certain period of time. The operational philosophy and strategies of the main force are different from those of ordinary investors. They pay more attention to macroeconomic trends and policy factors than short-term market fluctuations. Therefore, the main force prefers to invest in concepts based on macroeconomic, policy, market trend and other aspects of analysis and judgment.

Firstly, the main force prefers value investing. Value investing is a long-term investment strategy that emphasizes that investors should focus on the company's fundamentals and future development potential, rather than short-term market fluctuations. The main force usually selects companies with good fundamentals and potential for investment, and holds them for a long time to obtain stable returns.

Secondly, the main force likes trend tracking. Trend tracking is a short-term investment strategy that emphasizes that investors should follow market trends to operate. The main force usually pays attention to market trends, seizes opportunities in a timely manner, buys when the market is rising, sells when the market is falling, and obtains short-term profits.

In addition, the main force also likes to invest in theme stocks and hot sectors. Theme stocks and hot sectors are stocks that are highly concerned and sought by investors in the market, with high volatility and speculation. The main force usually pays attention to the hot sectors and theme stocks in the market, participates in them in a timely manner, and obtains high returns.

In general, the operational philosophy and strategies of the main force pay more attention to macroeconomic trends and policy factors, so they prefer to invest in concepts such as value investing, trend tracking, theme stocks, and hot sectors.
