  • Conference: Financial Revolution – Sentiment Analysis, AI and Machine Learning – Oct 30, 2018, Zurich

  • A Q&A Discussion with Vanguard Researchers on the “Fair Value CAPE Ratio” [Alpha Architect]

    As everyone whos been invested for the last ten years knows, post-financial crisis stock returns have been incredible. The chart below highlights the total returns for the S&P 500 Index, the MSCI EAFE Index, the MSCI EEM Index, and the MSCI ACWI Index. The results are hypothetical results and are NOT an indicator of future results and do NOT represent returns that any investor actually

  • RSI2 Strategy: Double returns with a simple rule change [Alvarez Quant Trading]

    While playing around with a 2 period RSI (Relative Strength Index) mean reversion strategy, I came up with a very simple rule change with a much larger impact on the results than expected. I doubled the compounded annual growth rate and cut the maximum drawdown in half. That never happens. In my optimization runs the best CAR went from lows 10s to the low 20s with this rule change. The
  • Consistent Momentum [Sutherland Research]

    Its been some time since I last posted so what better way to start than by quantifying and exploring a momentum strategy that was first introduced to me by the good guys at Quantpedia (www.quantpedia.com). If you havent heard of this site before, then I encourage you to check it out. For a nominal fee you get access to an incredible array of trading strategies that have been sourced and
  • Momentum Solutions for Retirement [Dual Momentum]

    As the surge of boomer retirements continues, commentators have given new thought to what safe withdrawal rates are for retirement accounts. The topic is especially significant given two additional factors. First, retirement balances are shockingly low for boomers (Ghilarducci 2015)[1]. Second, market fundamentals do not suggest that either bonds or equities will generate reliably strong rates of

  • Measuring Process Diversification in Trend Following [Flirting with Models]

    We prefer to think about diversification in a three-dimensional framework: what, how, and when. The how axis covers the process with which an investment decision is made. There are a number of models that trend-followers might use to capture a trend. For example, trend-followers might employ a time-series momentum model, a price-minus moving average model, or a double moving average
  • Factors: Shorting Stocks vs The Index [Factor Research]

  • Finance Journals Rarely Publish Articles with low T-stats [Alpha Architect]

    Coined by Rosenthal in 1979, the term file drawer problem refers to the notion that journal editors are biased toward accepting articles that include statistically significant results over those with nonsignificant results. The competition for increasing the citation count and improving journal impact numbers is considerable and primarily driven by the fact that articles with significant results
  • Review: Quantpedia.com [Throwing Good Money]

    Quantpedia contacted me a few months ago and asked if Id be interested in reviewing their site on my blog. Im always looking for new ideas for trading systems, so I said sure! (Disclosure: they provided me with free account access during the review period.) Quantpedia.com is an aggregator and interpreter of academic papers on trading and financial research. An encyclopedia of
  • Predictability of Betting-Against-Beta Factor [Quantpedia]

    The leverage aversion theory implies that returns to the betting-against-beta (BAB) strategy are predictable by past market returns: An outward shift in investors' aggregate demand function simultaneously increases market prices and increases the expected future BAB return. I confirm the prediction empirically and find that the BAB strategy performs better in times when and in countries where

  • Market intraday momentum [Eran Raviv]

    I recently spotted the following intriguing paper: Market intraday momentum. From the abstract of that paper: Based on high frequency S&P 500 exchange-traded fund (ETF) data from 19932013, we show an intraday momentum pattern: the first half-hour return on the market as measured from the previous days market close predicts the last half-hour return. This predictability, which is both
  • Seasonalities: Bad Period for Stocks? [Quintuitive]

    I just finished the implementation of another approach to finding repetitive calendar behaviour, and was quite surprised that the only short period for stocks, has just began. What are the odds of this?

  • Understanding Stock Price Range Forecasts [Jonathan Kinlay]

    Range forecasts are produced by estimating the parameters of a Geometric Brownian Motion process from historical data and using the model to project a large number of sample paths for the stock price over the coming month and year. For example, this is a range forecast for Netflix, Inc. (NFLX) as at 7/27/2018 when the price of the stock stood at $355.21: $NFLX As you can see, the great majority of
  • The dangerous disregard for fat tails in quantitative finance [SR SV]

    The statistical term fat tails refers to probability distributions with relatively high probability of extreme outcomes. Fat tails also imply strong influence of extreme observations on expected future risk. Alas, they are a plausible and common feature of financial markets. A summary article by Nassim Taleb reminds practitioners that fat tails typically invalidate methods and conventions

  • A Simple Hedging System With Time Exit [Relative Value Arbitrage]

    This post is a follow-up to the previous one on a simple system for hedging long exposure during a market downturn. It was inspired by H. Krishnans book The Second Leg Down, in which he referred to an interesting research paper [1] on the power-law behaviour of the equity indices. The paper states, We find that the distributions for t 4 days (1560 mins) are consistent with a power-law

  • Factor Investing Insights You Won’t Hear from Fama and French [Alpha Architect]

    Factor investing research has a long storied past. Fama and Frenchs 1992 and 1993 papers arguably put factor investing on the map, but truth be told, factor investing is an old topic with roots grounded in the so-called arbitrage pricing theory. We have a longer piece on the history of factor investing here. There is a monster empirical research effort to determine which factors describe
  • A Look At Past NDX Leaders That Gapped Down Big (For FB Traders) [Quantifiable Edges]

    After the market close on Wednesday, Facebook (FB) released earnings, and the news and future outlook was not viewed well. After closing at an all-time high on Wednesday, it traded down in excess of 25% in the after-hours. So it seems certain it will be opening Thursday with a sizable gap lower. I decided to take a look back at other leading NDX stocks that suffered large gaps down. I first
  • NDX Leader Performance Over Several Weeks After Large Gaps Down (FB Follow-Up) [Quantifiable Edges]

    This is a follow-up from my FB post last night. Traders that looked to take advantage of a possible bounce from todays open have seen moderate gains so far today. So what are the chances FB continues to bounce over the next several days and weeks? I re-looked at the study from last night, and examined how the other 9 instances performed over the next month.

  • We Are All FX Traders Now [Alpha Scientist]

    It's easy to forget that virtually all asset classes we hold are priced in US dollar terms. Portfolio valuations are as impacted by the denominator (US dollars) as by the numerator (asset value) Commodity assets like oil and gold are highly (negatively) correlated to US dollar strength. Certain equity asset classes, especially emerging equities, are extremely negatively correlated to USD
  • Conviction, evidence, and accepting ignorance [Factor Investor]

    Countless studies have demonstrated that incorporating feedback loops into life is beneficial. Want to improve at work; seek a mentor. Want to nix that slice; get a swing coach. Want to get in shape; find a trainer. Want to become a better surgeon; get a coach. When left to our own designs, discipline falls away and we fail to learn and grow. Investing is no different. Yet, because the topic of

  • Machine Learning, Subset Resampling, and Portfolio Optimization [Flirting with Models]

    Portfolio optimization research can be challenging due to the plethora of factors that can influence results, making it hard to generalize results outside of the specific cases tested. That being said, building a robust portfolio optimization engine requires a diligent focus on estimation risk. Estimation risk is the risk that the inputs to the portfolio optimization process (i.e. expected
  • 2D Asset Allocation Using PCA (Part 1) [CSS Analytics]

    Asset allocation is a complex problem that can be solved using endless variations of different approaches that range from theoretical like Mean-Variance to heuristic like Minimum Correlation or even tactical strategies. Another challenge is defining an appropriate asset class universe which can lead to insidious biases that even experienced practitioners can fail to grasp or appreciate.

  • Practical Statistics for Algo Traders [Robot Wealth]

    How do you feel when you see the word statistics? Maybe you sense that its something you should be really good at, but arent. Maybe the word gives you a sense of dread, since youve started exploring its murky depths, but thrown your hands up in despair and given up perhaps more than once. If you read lots of intelligent-sounding quant blogs, you might even feel like your lack of
