Mean Reversion Impact
Mean reversion is the theory that asset prices and historical returns eventually return to their long-term average or mean. In the context of derivatives, this impact is significant for strategies that rely on price trends.
If a market is strongly mean-reverting, trend-following strategies will suffer, while strategies that sell volatility or trade ranges will perform well. The impact of mean reversion on account longevity is substantial, as it determines the viability of different trading styles across market cycles.
Traders must be able to identify whether the current market environment is trending or mean-reverting to adjust their risk and strategy accordingly. Failing to recognize a shift in regime can lead to significant losses, as strategies become misaligned with the prevailing market physics.
