Market ecology refers to the complex interplay and dynamics among various participants, assets, and factors within financial markets. Just like in natural ecosystems, different entities in the market interact with each other, creating a delicate balance that can affect asset prices, trading volumes, and market volatility.
Market ecology theory views trading strategies akin to biological species, where invested capital resembles the population size of these species. This perspective fosters a diverse ecosystem of trading strategies. The impact of a specific strategy within this ecosystem depends greatly on the capital it attracts.
Reference [1] explores the impact of trading strategies on market volatility by creating a trading strategy ecosystem that includes value investing and trend-following strategies. The authors pointed out,
The simulation results presented in this study show that the impact of a trading strategy on market volatility may be related to both the characteristics of the strategy itself and the market ecology in which the strategy is located. In a market composed of the trend-following strategy and the value strategy, market volatility is minimized when the capital of the two is matched. This is because they in this situation have the least liquidity shocks on the market, which is a combination of their behavioral convergence and maximum possible impact on the market. In contrast, in a market composed of the trend-reversal strategy and the value strategy, the more capital invested in them, the higher the volatility of the market. This may be a result of the strong behavioral convergence of them, which is greater than 84% in this paper. From the perspective of behavioral convergence, there is a greater difference between the value strategy and the trend-following strategy compared to the trend-reversal strategy. This implies that sufficient behavioral heterogeneity among trading strategies can stabilize the market to a certain extent. The above results suggest that having diversified trading strategies may be beneficial for financial market stability.
In short, the paper concludes that having a diversity of trading strategies in a market can stabilize it and lower its volatility.
This result is interesting. Can it be applied to portfolio management? This would lead to the conclusion that one should have a diversified, heterogeneous portfolio of trading strategies in their investing approach.
