问题如下：
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
B.
Statement 2
C.
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.
我想请问一下，当时李老师解释的时候是说这个是受市场波动影响，如果当时的波动正好不利于买卖方向，则有风险。那如果急着买的话，可能是正好不利于自己的趋势？不是应该慢点交易？
