This paper focuses on “organization capital,” representing intangible assets in a firm’s key employees that is not captured by classic value measures such as book-to-market. The authors propose a structural model to analyze the impact of organizational capital on asset prices and argue that

Multiple collateralized loan obligation (CLO) ETFs have been launched since 2020 CLOs are promoted as low-risk fixed-income products However, these simply represent diluted equity exposure and offer limited diversification benefits INTRODUCTION The U.S. leveraged loan market has increased from $100

The increasing role of intangible assets compared to physical assets in our economy has been accompanied by increased research into their impact on asset prices and returns. Studies such as the 2020 papers “Explaining the Recent Failure of Value Investing,” “Intangible Capital and the Value

There has been a surge in correlation between US stocks and Treasuries over the last couple of years. To illustrate, below we’ve shown the rolling 3-year correlation between US stocks and 10-year Treasuries since 1900 (based on monthly returns). Note the spike at the far right of the chart. What

sum: quant_rv was already beating SPY in our last post, with a long-only approach. Testing the remaining (flat) days finds that they’re dominated by losers, so if we go short (using SH ETF) instead of flat, boom! performance jumps again recap quant_rv is a simple quant strategy written in R that

An index tracking portfolio1 is a portfolio designed to track as closely2 as possible a financial market index when its exact replication3 is either impractical or impossible due to various reasons4 (transaction costs, liquidity issues, licensing requirements…). In this blog post, after reviewing

Intuitively fund managers should create more alpha when volatility is higher However, neither mutual nor hedge fund managers have been able to do so Likely explained by fund managers being less rational than assumed INTRODUCTION “However, a period of higher volatility is ‘a good environment for

Idiosyncratic volatility (IVOL) is the volatility of a security that cannot be explained by overall market volatility—it is the risk unique to a particular security. IVOL contrasts with systematic risk, which is the risk that affects all securities in a market (such as changes in interest rates or

TL;DR ~ This post explores adding a normalized Average True Range (nATR) measure that behaves in a similar fashion to other volatility measures, including a “low volatile anomaly” and nATR gives quant_rv a nice boost in backtesting performance. Not all goals for quant_rv are met yet, but we’re

The 60/40 portfolio, the bread-and-butter portfolio of today’s wealth management industry, is limited to just two core drivers of returns: equities and bonds. Is there someplace else we can turn to for a compelling yet distinct source of returns? Yes, there are several places to look in fact, one

This paper acknowledges the pivotal role of earnings calls in disseminating value-relevant information, with particular emphasis on the Q&A segment. However, it confronts the inherent challenge posed by the unstructured nature of language in these calls, complicating quantitative analysis. In

SUMMARY Identifying the right benchmark for a fund or portfolio can be difficult Many common metrics like correlation or betas do poorly for benchmark selection Combining metrics is more effective INTRODUCTION Is gold the right benchmark for gold miners? Although these companies focus on excavating

Market cap and dollar volume are two commonly used metrics for filtering a trading universe by size of security. Does it matter which one you use? In this post, I quantify the difference between market cap and dollar volume and explain the kinds of stocks that may unexpectedly appear in your

The pace of aggregate demand in the macroeconomy exerts pressure on interest rates. In credible inflation targeting regimes, excess demand should be negatively related to duration returns and positively to curve-flattening returns. Indeed, point-in-time market information states of various macro

Today’s newsletter is based on a reader’s suggestion. We look at k-medoids which is a villain in the popular Nintendo game Metroid. No it’s not. But if you know Metroid, you have to agree: It sounds like one! It’s actually a powerful method used in data science to cluster similar data

One of the simplest and most pragmatic approach to volatility forecasting is to model the volatility of an asset as a weighted moving average of its past squared returns1. Two weighting schemes widely used by practitioners23 are the constant weighting scheme and the exponentially decreasing

You may remember our blog post from the end of March, where we tested the current state-of-the-art LLM chatbot: Time flies fast. More than six months have passed since our last article, and half a year in a fast-developing field like Artificial intelligence feels like ten times more. So, we are here

Whenever you want to estimate a model for multiple time series, the Vector Autoregression (VAR) model will serve you well. This model is suitable for handling multiple time series in a single model. You will learn here the theory, the intricacies, the issues and the implementation in Python and R.

The Jegadeesh and Titman (1993) paper on momentum established that an equity trading strategy consisting of buying past winners and selling past losers, reliably produced risk-adjusted excess returns. The Jegadeesh results have been replicated in international markets and across asset classes. As

In today’s newsletter, you’ll use the OpenBB SDK to download news for a topic. Then, you’ll use OpenAI and build a prompt to predict the sentiment of a news headline. You’ll bring it all together with LangChain. The result is a pandas DataFrame with a column of news headlines and a column

While out hiking, I found this rock. Evidently it was created by aliens, as can be shown by a probability argument. The following table gives measurements made on the rock. The first two rows give the overall length and width of the rock. Each of the next six rows, after the first two, gives

Financial time series that are structured as data sampled at a uniform time interval, e.g., hourly, daily, weekly, or monthly, are called discrete-time time series and referred to, from a digital signal processing (DSP) perspective, as being in the “time domain.” Technical market analysts

Usually, in algorithmic trading, we talk about AutoRegressive Integrated Moving Average (ARIMA) models. They’re very popular in the industry. You might remember that the “d” component in the model can be 0, 1, 2, etc. What if 'd' could take fractional values? We’ll learn about such

An ETF-Based Measure of Stock Price Fragility Renato Lazo-Paz (University of Ottawa) July 2023 A growing literature employs equity mutual fund flows to measure a stock’s exposure to non-fundamental demand risk – stock price fragility. However, this approach may be biased by confounding

I’ve previously discussed the Volatility Risk Premium (VRP) and how it differs from the Equity Risk Premium (ERP). Probably the most interesting difference, from the perspective of the trader, is that the VRP may be somewhat amenable to timing – more than the ERP at any rate. In this article,

In this article we are going to continue the discussion on portfolio insurance strategies. An exhaustive description of this methodology was already presented in the article Introduction to CPPI (https://quantpedia.com/introduction-to-cppi-constant-proportion-portfolio-insurance).

Long-term returns for US Treasury bond funds with a constant maturity (like IEF, TLT and SHY) have been quite predictable simply using initial Treasury yields as an estimate. This observation was popularized by John Bogle. Here’s an excellent recent look from Portfolio Optimizer. How predictable?

Over the very long term, while value stocks have been less profitable and have had slower growth in earnings than growth stocks, they have provided higher returns. Among the reasons are that value stocks have traded at substantial valuation discounts compared to growth stocks, and reversion to the

Lately, I’ve been thinking a lot about the Volatility Risk Premium (VRP). The VRP makes much more sense (to me, at least) when I have the Equity Risk Premium (ERP) for context and comparison. So, in this article, I want to discuss the ERP and the VRP, their similarities and differences, and how I
