Harding begins the meeting by asking Yellow about factors that affect the selection of an appropriate trading strategy. Yellow tells Harding:
Statement 1 Trading with greater urgency results in lower execution risk.
Statement 2 Trading larger size orders with higher trade urgency reduces market impact.
Statement 3 Securities with high rates of alpha decay require less aggressive trading to realize alpha.
Which of Yellow’s statements regarding the factors affecting the selection of a trading strategy is correct?
选项：
A.Statement 1
Statement 2
Statement 3
解释：
A is correct.
Greater trade urgency results in lower execution risk because the order is executed over a shorter period of time, which decreases the time the trade is exposed to price volatility and changing market conditions. In contrast, lower trade urgency results in higher execution risk because the order is executed over a longer period of time, which increases the time the trade is exposed to price volatility and changing market conditions.
B不是紧急的大单吗？不应该对市场影响大吗？
