I disagree. I believe this violates all options.

Priority of Transactions is always violated if your trading on material info because you are affecting the stock price.

Due dilligence because you are not doing any research or have any basis for making this trade.

Material Info because he is obv. trading on private information.

Please correct me if I am wrong.

The answer is B because he did nothin in regards to research on the stock. He also did not see if that stock was suitable for his clients accounts.

A is not the right answer because we do not know if that "huge trade" was already made or not...the question does not say.

C is not correct because this information would not count as material, non public inforrmation. If the trade has already been made, then it would be in public records.

I am making a lot of assumptions here, but to pick one right answer that would have to be what you would need to do.
