Postamble: I’m taking a brief mid-year blog hiatus to recharge and refresh. In my absence, I’ve scheduled a series of posts that don’t require too much input from me. Speak soon! (Very soon – I’m only away for two weeks).

Rolling Alpha posts about finance, economics, and sometimes stuff that is only quite loosely related. Follow me on Twitter @RollingAlpha, or like my page on Facebook at www.facebook.com/rollingalpha. Or both.
