I think the happy investor is this investor who receives a constant income from his investments, and which this income suits.
It does not matter what market it invests, it is important how often it falls into the goal. A good investor will not share everything on black and white, he is still in both markets.
Everyone will really be happy if his investments are serving him right and always at profit.
Well, there are investors that won't mind sharing what's with their portfolio and strategy why they keep on winning. It's just a matter of how grateful they are and why they're sharing unless they have some sales pitch at the end of each conversation they make to someone who's interested talking to them.
