Jump on bandwagon

Someone sent an e-mail to me, arguing that some of the investors are knowledgeable and wanted to jump on the bandwagon to claim for compensation.

I asked him to call me by telephone. He did, and we had a chat. I realise that he was not aware about the details of the structured product. He was arguing from a "thereotical" angle.

I explained that there is no way for any knowledgeable person to invest in the structured product, if he has been properly informed about the risk. The return of 5% is not worth the risk.
He still did not accept my point.

I hope that other people who claimed that the investors were "greedy" should meet and talk to them, before forming this opinion.
