  • Algorithm design and correctness [Quantum Financier]

    Giving software you wrote access to your or your firms cash account is a scary thing. Making a mistake when manually executing a trade is bad enough when it happens (you can take my word for it if you havent yet), but when unintended transactions are made by a piece of software in a tight loop it has the potential to be an extinction event. In other words, there is no faster way to

  • Are Factors Better and More Diversifying Than Asset Classes? [Alpha Architect]

    Factor investing promises outperformance at low cost. But to add value in a portfolio, it must deliver positive risk-adjusted returns and with low correlation to existing holdings.

Therefore, factors such as Value and Momentum should only be

  • Sunday Marks the Quantifiable Edges Subscriber Letter s 10th Anniversary [Quantifiable Edges]

    Sunday Feb 18th marks the 10th anniversary of the Quantifiable Edges Subscriber Letter. I can hardly believe I have been writing it for 10 years, but it is true.

  • A Closer Look At The Links For Stocks, Interest Rates, And Inflation [Capital Spectator]

    Does history offer a reason to be cautious on the outlook for stocks if inflation and interest rates are rising? Yes, sort of, according to a New York Times article published on Thursday. Hedging just a bit, the Times piece relates that its long been a truism that higher inflation and its close cousin, higher interest rates, are deadly for stock prices. But in the wake of this months
  • Spx Low Vol Streak, Update [Voodoo Markets]

  • Trading the Equity Curve [Alvarez Quant Trading]

    A popular method for determining if a strategy should be kept trading is trading the equity curve. What this means we apply an indicator, say 200-day moving average, to the equity curve.

The general idea being that you get

  • Should You Dollar-Cost Average? [Flirting with Models]

    Dollar-cost averaging (DCA) versus lump sum investing (LSI) is often a difficult decision fraught with emotion. The historical and theoretical evidence contradicts the notion that DCA leads to better results from a return perspective, and only some measures of risk point to benefits in DCA. Rather than holding cash while implementing DCA, employing a risk managed strategy can lead to better DCA
  • Value Factor – Intra vs Cross-Sector [Factor Research]

  • Low Risk Anomaly in Banking Industry and Its Implications [Quantpedia]

    Traditional capital structure theory in frictionless and efficient markets predicts that reducing banks leverage reduces the risk and cost of equity but does not change the overall weighted average cost of capital (and thus the rates for borrowers). We test these two predictions. We confirm that the equity of better-capitalized banks has lower beta and idiosyncratic risk. However, over the last

  • Thoughts On Dealing With Historically Abnormal Markets [Quantifiable Edges]

For instance, I looked back to 1960 with the SPX for to find other times SPX closed down > 10% from a 250-day closing high within 2 weeks of
