  • Optimal Retirement Planning Using Certainty-equivalent Spending and TensorFlow (Development)
    http://blog.streeteye.com/blog/2016/08/safe-retirement-spending-using-certainty-equivalent-cash-flow-and-tensorflow/

    Historically, what would have been the optimal allocation and spending plan for retirement?

    If you are maximally risk-averse, the Bengen 4% rule holds up: start by spending 4% of your portfolio and increase annually for inflation. If you are less risk-averse, a more flexible rule like a fixed spending amount plus a percentage of assets might make more sense.

    Using TensorFlow, we explore the universe of stock/bond allocations and spending rules to find the plan that would have maximized certainty-equivalent spending, at various levels of risk aversion.

  • Risk Arbitrage: Investing and Poker (Development)
    http://blog.streeteye.com/blog/2013/08/risk-arbitrage-investing-and-poker/

    I wrote a blog post exploring analogies between investing and playing the game of poker. Both are games of quantitative thinking about imperfect information and psychology. But real-world markets don't reward bluffers.

  • Active vs. Passive Investing and the “Suckers at the Poker Table” Fallacy (Development)
    https://blogs.cfainstitute.org/investor/2016/02/02/active-investing-really-the-losers-game/

    This is a thought experiment on what would happen if more and more people invest passively. There's no such thing as a 100% purely passive investor: we are free to pick a strategy but not avoiding the choice. As more people invest more passively, they save on expenses, but market efficiency decreases. The ideal "Warren Buffett" active investor can always exploit any "suckers." At some point, though, the less active investing there is, the more excellent opportunities there are for remaining active investors to exploit.

  • Quantitative Fun with Fund Names (Other amazing things)
