Well, all I can say is that today has been one of the worst days of my portfolio's life. I'm not concerned about my core holdings -- Disney (NYSE: DIS), Coca-Cola (NYSE: KO), General Electric (NYSE: GE), stuff like that -- but, boy oh boy, are my financial positions taking some major hits!

I know, I know -- you're saying to yourself, "uh, buddy, didn't you realize this was going to happen?" Sure, but when the theory becomes reality, that's when the torture really starts to set in. Not sure if you caught the wave of downgrades today -- if you didn't, check out Eric Buscemi's post about it -- but I got hammered by one of them. MFA Mortgage (NYSE: MFA) was downgraded by Keefe Bruyette on book-value concerns. As I write this, it's trading down over 15% -- oooh, it hurts to write such a double-digit figure -- on, get this, volume of over 15 million shares. The 30-day average volume is closer to 4 million shares. I'm writing this with a couple hours to go to close! It's going to be a huge volume day once all is said and done. I also own Newcastle Investment (NYSE: NCT), CapitalSource (NYSE: CSE) and MFA preferred shares (NYSE: MFA-A).

Have I been shaken out yet? No. In fact, in terms of MFA, I personally think that it is a buy, even though it could be in falling-knife mode right now (that's always difficult to discern). I know Timothy Sykes would disagree on this strategy, so you should check out his post for some balance. With Ben Bernanke most likely set to cut the Fed Funds rate even further, MFA should benefit, as should most financials. I also like CapitalSource, but I am a little wary at this point of Newcastle -- I think it will recover, but that one's been particularly volatile. As they say, when there's blood on Wall Street, that's sometimes the best time to do some judicious buying (after a ton of due diligence, of course). And, as a postscript, if you want to do only safe buying, then Disney, Coke and GE might be good ideas to look at -- GE has an especially interesting yield right now.
