IPS这里没有考虑到税的因素，基于错误IPS做的投资，也能判断为diligence and reasonable basis吗

NO.PZ202304110100000304 问题如下 es Telline violate any CFA Institute Stanr when he places the buy orr for shares in the technology company for Caper’s account? A.No. B.Yes, relating to fair aling. C.Yes, relating to ligenanreasonable basis. Telline is careful to consir the investment’s suitability for Caper’s account. Telline’s actions are consistent with CFA Institute Stanr III(A)–Loyalty, Prunce, anCare anIII(B)–Fair aling. Telline termines ththe other client es not have the cash available in his account anselling existing holngs es not make sense. 老师，请问这里另一个客户也有相同风险偏好，但因为账户钱不够且T认为卖其他股票也不合适，所以就没给另一个客户买。这里是不是有违反fair aling的嫌疑呢？虽然T做过判断了，但是他是不是应该至少通知到这个客户呢？客户可以决定给账户打钱来买这个股票呀，现在客户都不知道这个事儿。
