  • Impact of High Equity Valuations on Safe Retirement Withdrawal Rates [Flirting with Models]

    While valuation-based market timing is notoriously difficult, present and future retirees should prepare for muted U.S. stock and bond returns relative to historical experience. High valuations suggest that retirement withdrawal rates that were once safe may now deliver success rates that are no better – or even worse – than a coin flip. This outlook is by no means a call for despair, but rather

  • Exploring Our Scraped Options Data Bid-Ask Spreads [Black Arbs]

    Compared to the equity market, the options market is a level up in complexity. For each symbol there are multiple expiration dates, strike prices for each expiration date, implied volatilities, and that's before we get to the option greeks. The increased complexity presents us with more opportunity. More complexity means less ground truth, more errors, more gaps, and more structural

  • Visualizing Tail Risk [Eran Raviv]

    Tail risk conventionally refers to the risk of a large and sharp draw down of the portfolio. How large is subjective and depends on how you define what is a tail. A lot of research is directed towards having a good estimate of the tail risk. Some fairly new research also now indicates that investors perceive tail risk to be a stand-alone risk to be compensated for, rather than bundled together
  • Trend Following 140 Years of Data Supports its Value [Wisdom Trading]

  • Measuring Market Divergence for Systematic Trend Following [Golden Compass]

    In his 2012 book, Nicholas Nassim Taleb defined the term antifragile for representing things that benefit from disorder.

In the CTA and technical analysis domain, divergence is defined as the strength of directional shifts in market
  • A Gentle Guide to Global Tactical Asset Allocation [Flirting with Models]

  • Sector trading using the 200-day moving average [Alvarez Quant Trading]

    A user commented on ETF Sector Rotation post about a simple idea for trading the sector ETFs, which I cant believe I have never tried.

Rules If the Select Sector SPDR ETF (XLY, XLP, XLF, XLE, XLV, XLI, XLB, XLK, XLU) is above its 200-day moving average for the last 5 days, then buy 10% of that ETF. If it is below the 200-day
