This article analyzes the phenomenon of volatility aggregation and its causes, and explores the amplification effect of information flow and leverage effect on volatility. In view of the failure of traditional risk control models in periods of high volatility, it is proposed to use time-varying volatility models and stress tests to guide traders to establish an adaptive risk management framework and achieve steady participation in the ups and downs of market cycles.

This article analyzes the limited arbitrage theory and explores why market pricing deviations can exist for a long time. Analyze the obstacles that fundamental risks, noise trader risks and liquidity constraints have on error correction mechanisms, revealing the fragility of smart money. Guide retail traders to be wary of obvious error traps, and prioritize ensuring survivability and trading discipline in inefficient markets.

This article explores how time preference drives trading behavior. Analyze the intertemporal inconsistency caused by hyperbolic discounting, the distortion of rationality by high-frequency feedback, and how action bias destroys compound interest.

Leveraged derivatives amplify returns while introducing non-linear risks. This article analyzes the nature of risk repricing, path dependence effects, tail risk failures and behavioral bias distortions of leverage. Retail traders must recognize their fragility and achieve sustainable trading based on risk control.
