  1. Cost-First New Year’s Resolutions

    It’s the last day of the year, so it’s time for the tradition of trying not to think about how you failed at your New Years resolutions. The making of New Years resolutions is a durable tradition, but not because it works at its stated goal: New Years

  2. Alpha Buybacks and Beta Buybacks

    Buybacks by quarter, courtesy of S&P by way of Yardeni Research. One of the classic tropes of lazy financial journalists goes like this: XYZ Co spent half of their free cash flow on buybacks this year, but the stock dropped! They lost their shareholders billions of dollars! What

  3. Volatility: One Theorem, One Lemma, Zero Paradoxes

    A common theme I’ve mentioned — in pieces on mortgages, industry demographics, energy, and bubbles generally — is the idea that the perception of lower risk creates the reality of higher risk.

  8. Your Life is More Financialized Than You Think

    There are really only two things that get the financial sector in trouble: excess leverage, and maturity transformation. Excess leverage is easy to understand. If you have $100 of assets, and you borrow $50 against it, you’re safe as long as the value of your assets never declines by
