I owned CSQ until recently. I was rebalancing my portfolio and I lost money in CSQ. I've lost money in most of the closed end funds I have owned. You might do well buying when I sell and vice versa. It is a lot cheaper than when I bought it...
I guess I look at the stocks it owns and they don't look bad, but a little index-like. The only way you can get 10+% divi from index fund is to have a lot of leverage or "steel" the money from NAV. The NAV has been dropping like a rock and the discount has been expanding.
I'm not sure that CEF's selling at a discount really protect you from down side risk... at least that is not my experience with them. It seems to me that when the market is weak, CEF's are weaker. You see the NAV drop and the discount expand...
