"portfolio_rationale": "The portfolio is adjusted to include positions with significant mean-reversion potential while adhering to the strategy's constraints. Two new positions are added based on their extreme and large deviations from the 200-day moving average, indicating strong mean-reversion opportunities. All existing positions are held as they do not show significant deviations from their means, aligning with the strategy's avoidance of overtrading."

"portfolio_rationale": "The portfolio is adjusted to include positions with significant mean-reversion potential while adhering to the strategy's constraints. Two new positions are added based on their extreme and large deviations from the 200-day moving average, indicating strong mean-reversion opportunities. All existing positions are held as they do not show significant deviations from their means, aligning with the strategy's avoidance of overtrading."
