The annualized rate of return of social security funds exceeds 7%

Social security fund has always been a "sharpshooter" in the investment field, and its investment style is steady, so it has always been known as "smart money". Since its establishment 24 years ago, the average annual return on investment of social security fund has reached 7.36%, and its scale has grown by leaps and bounds, killing a number of professional investment institutions and becoming the "YYDS" of the investment community.

Judging from the position structure of social security fund in recent two years, its thinking is mainly "two-pronged". First, pay attention to the fact that the industry valuation is at an absolute low level, and the pessimistic expectation of performance has been fully reflected. Next, the performance is expected to usher in a recovery and reverse the industry, which is mainly used as a bottom position. Second, we prefer the growth track that is currently in a high boom cycle and is strongly supported by national policies and has long-term growth logic.

"Value investment is not holding still, but pursuing an absolute cost performance. In the short term, it will increase greatly. If it is profitable, it needs to be profit-taking.

The national social security fund mainly comes from financial allocation, state-owned capital transfer, lottery public welfare fund, etc., and its source is long-term and stable, and it is a typical long-term fund. By the end of 2024, the size of the national social security fund was about 3 trillion yuan.

The national social security fund has long been firmly optimistic about the value of A-share investment, which is a model of long-term investment and value investment in the capital market. The relevant person in charge of the National Social Security Fund Council has repeatedly stated that the National Social Security Fund Council has always adhered to long-term investment, so that the fund investment focuses on sharing the long-term benefits of national economic growth and the fruits of the healthy development of the capital market, and always maintains strategic strength in the short-term fluctuations of the market.

It is understood that the social security fund has repeatedly seized the opportunity to add positions in the A-share market. Li Xunlei, chief economist of Zhongtai International, said that social security funds are different from ordinary medium and long-term funds, and the allocation ratio of equity assets is usually high, which is the main reason why the long-term investment return rate of social security funds can continue to be ahead of other medium and long-term funds.

Although the investment income of social security fund is excellent, as an ordinary investor, it can’t completely "copy homework". Liu Youhua, research director of Paipai.com, suggested that the social security fund positions should be treated rationally. First, the social security fund income comes from the portfolio, not a single stock. The social security fund positions are scattered, and the investment is a portfolio of stocks. The single stock has little impact on the overall income of the social security fund; Secondly, the investment style of social security fund is not suitable for all investors, and the investment cycle of social security fund is long. In the choice of investment target, it tends to buy companies that can continuously create value at reasonable prices for long-term holding, and will not care about the stock price fluctuation during the period when the company’s fundamentals have not changed significantly; Third, the news of social security fund positions has a certain lag, so it is impossible to keep completely synchronized with the social security fund. However, it is undeniable that social security funds have strong pricing ability and research ability in the A-share market, and most of their positions are companies with excellent fundamental texture.
