In any business like this there will be underperforms. I think the bad stuff was overblown by some publisher that didn't think to dig for the whole story. An important fact today was that the dividend does not include return of capital and never has. Tells you that the periodic sale of stock goes right into investments and not making up for wasted money.
Over the years I have owned several stocks that I decided to buy after actually meeting executives or sales people of those companies. There is other stuff too, but if a company is staffed by quality people that work hard and care about their company and are not drunks and philanderers and other bad things, then that at least tells you something about what you are about to invest in. I have never met anyone at MAIN, although I have corresponded with them and they actually answer back, but never any bad news about these guys, plus as mentioned before, they actually own what they manage.
"looming bad news" is something you would sell on? Especially since MAIN has been a stellar performer. I think you have other motives, or maybe you just like to spout off for no real reason. I wouldn't say that, but you provide zero reasoning. Besides that you appear to be dead wrong.
