What defines the optimal timing for closing positions affected by synchronization risk?

• A. When both stocks experience the same growth rate
• B. When divergence does not converge within a specific period
• C. When trading volumes increase significantly
• D. When market news favorably impacts both stocks

Answer: (B)

The optimal timing for closing positions affected by synchronization risk is defined by the situation where divergence does not converge within a specific period. This concept revolves around the notion that synchronization risk occurs when two related securities move together as expected based on their historical correlation. If a trader is expecting them to converge (meaning they will move back toward a historically normal relationship) and this expected convergence does not happen within a predetermined timeframe, it signals that the relationship is breaking down, warranting the closure of positions to mitigate potential losses.

In the context of trading strategies, if divergence continues beyond a set period, it suggests that the underlying factors that maintain their relationship may have fundamentally changed, making it prudent to exit the position. The other options do not capture this risk management approach as effectively. For instance, waiting for both stocks to show the same growth rate or relying on market news, while they may provide insights or indicators, do not specifically address the timing based on ongoing divergence. Similarly, an increase in trading volumes could indicate various market behaviors, but without addressing the specific synchronization risk, it does not serve as an ideal trigger for closing positions.
