Mea culpa investing. Now, there's a style -- but one that works for the bulls, not for the bears.

In the past 24 hours we have seen some heady mea culpa-izing. First we got Facebook (FB) CEO Mark Zuckerberg telling the truth that the company got caught flat-footed with the wrong software for mobile. That was a breathtaking interchange. Humility is in incredibly short supply in Silicon Valley, so I found it delightful. It was charming!

But it was also important because, until that interchange, we were hearing nothing from management, whoever that was, about any issues at all. In fact, that quarterly conference call made investors feel as though Facebook had mobile down to a T, and that's one of the chief reasons the stock got hammered so hard.

So we've seen recognition that the company has been going the wrong way and an understanding of the opportunities for mobile and for the Nokia (NOK) Lumia 900. With that, Facebook has taken a step toward establishing credibility in people's eyes.

An understanding of what went wrong is incredibly positive, especially when you have an obviously intelligent and cunning guy up top who is willing to admit that the initial public offering was a disappointment. Hey, don't snicker -- we didn't even hear that before!

Two other issues remain, though.

The first is whether Facebook can monetize mobile better than others, given how little the current advertisers like it away from Google (GOOG)/Yelp (YELP) search.

The second is the lock-ups. If you really think the company is going to "fix" mobile, wouldn't you want to let settle the billions of shares that are going to come to the market? I mean, I am a huge believer in AIG (AIG), but the government overhang has mattered tremendously to timing.

No matter what, though, the mea culpa here makes Facebook more worthwhile as an investment, and the rally makes sense to me. I don't want to trade it personally. But a play here is not inexplicable -- and it is rational.

Away from this, I think the German supreme court's ruling likewise amounted to a mea culpa. The ruling basically says, "Yeah, we are a part of Europe and we are a part of the federation, so we have to pay our dues, too."

That's what's been lacking in Europe -- some "all for one and one for all" non-Mickey Mouse compact -- and I think we got one here.

I instantly heard that the Germans are committing suicide with this, but I heard it only from people who are (a) underinvested (b) short the euro and/or (c) short gold.

So, alas, I know it's good news. Anything that makes for more of a federation, galactic or otherwise, is a win for the bulls. This supreme court decision paves the way for more unity and recognizes that Germany is no longer an island.

That's what the bulls wanted.

They got it.

Two "I'm sorrys" send market higher.

If only things were always as simple as that. But they are for the moment, that's for certain.
