流動性黑洞下投資行為研究
[Abstract]:In the context of global financial integration and liberalization, the international finance is intertwined with each other, and the liquidity risk is also increasing. Under the premise of the financial crisis, the financial market has been greatly threatened. The disappearance of liquidity in the short term has caused sharp volatility in financial markets and has become the focus of attention of financiers and government policy-makers. Throughout the financial crises, the vast majority of financial investors are unable to trade normal assets due to liquidity imbalances. Therefore, the establishment of a stable and efficient financial market will greatly enhance investors' confidence in the market, which is also an important prerequisite for the healthy and orderly development of the financial system. Therefore, this paper firstly analyzes the phenomenon of liquidity disappearance in China's financial market by combining the existing theoretical assumptions and theoretical models, and explores whether there is a liquidity black hole. To find a practical explanation method to test the anomalies in the financial crisis, to test the existence of liquidity black hole in the current securities market in China, and to confirm the main characteristics of the liquidity black hole before and after the outbreak of the liquidity black hole. In studying the current situation of liquidity in China's stock market, the liquidity black hole is regarded as the positive causal relationship between the market price return rate and the purchase order between investors under the normal trading situation. Therefore, based on positive feedback trading, the relationship between the logarithmic return rate of stock and the amount of buyer's order and the quantity of seller's order is tested at the same time. The main factors affecting the liquidity black hole are judged by the trend of the difference of the price in a fixed range. In order to analyze the inherent mechanism of the liquidity black hole in the market, this paper studies the trading behavior and optimal asset allocation strategy of different investors under the LOF fund market environment, and the extreme market environment under the assumption of the liquidity black hole is added. Further study the investment behavior between traders in extreme environments and dig out the deeper causes of the liquidity black hole. Finally, through the conclusion of this paper, in order to improve the financial market environment and promote the stability of the financial market, the paper puts forward the main suggestions and measures to alleviate the liquidity black hole.
