It's a quite common response when people mention their returns etc. that "it's a bull market", I presume that it is intended to discredit the actual return numbers. Seasoned veterans, or those who present themselves to be at least, may say something along the lines of "let's see you in a bear market" etc.
I see the point that, in a bull market, most strategies that involve buying stocks will make money, as stocks go up. I do think that people who espose "its a bull market" are full of it since you can still look at your return vs the market on a risk adjusted basis to see if you outperformed, but I post to those people:
If its a bear market, and I post good returns because I'm going short, does that mean those returns have no credibility?
If anyone can make big returns in a bull market, why can't anyone make good returns in a bear market?
If its that easy to identify that its a bull market and you can make money by buying stocks, why aren't you rich?
Nothing personal here as no-ones ever said it to me - but I do wonder when I see people post "its a bull market".
