SZR不是制定交易商了么，那怎么违反了交易流程了呢？上一题不是不违反，怎么这一题就违反了？

问题如下：

4. Does Zane’s revision of SZR’s trading process violate the CFA Institute Asset Manager Code of Professional Conduct?

选项：

No.

Yes, only with respect to best execution.

Yes, with respect to best execution and fair, equitable trade allocation.

解释：

C is correct.

Zane should have pursued best execution for all clients in the fund (which is not accomplished by placing trades with the local financial advisor first versus with national brokers or electronic networks), and fairly traded for all clients. While Sastre is welcome to direct trades, Zane’s change in procedures harms other clients.
