The operation of Japan's stabilization fund is not ideal. In order to counter the influence of international investment funds, the Japanese government used the Postal Savings Fund to enter the market to buy stocks when the stock market fell in recent ten years, so as to reverse the decline of the stock market. But the effect is not obvious.

The key to the expected effect of the stabilization fund lies in whether the stock market faced by the stabilization fund is a perfect market, whether the macro-economic aspects of the market are good, and whether it supports an upward trend of the stock market. If these conditions cannot be met, when and how the stabilization fund will intervene will be a difficult problem. If we don't grasp it well, it will aggravate the irregularity of the market and delay the time of self-repair and development of the market. The result may be that the goal of stabilizing the market cannot be achieved, and the stabilization fund itself will suffer heavy losses.
