The size premium is one of the factors that we have researched and dug into several times on the blog. You can find just a few here, here, and here. This paper though took a fresh look at the size premium and adds a new perspective that we haven’t previously covered. What are the research

Concept: Large price moves tend to be followed by large price moves, and small price moves tend to be followed by small price moves (Volatility Clustering). Research Question: Can we improve performance of the original volatility clustering model via standard deviation filtering of large price

When developing a new trading strategy you are usually confronted with multiple tasks: Design the entry, design the exit and design position sizing and overall risk control. This article is about how you can test the edge of your entry signal before thinking about your exit strategy. The results of

To generate returns that are different than the market, we must adopt a positioning that is different than the market. With the increasing adoption of systematic factor portfolios, we explore whether an anti-factor stance can generate contrarian-based profits. Specifically, we explore the idea of

Tradable economics is a technology for building systematic trading strategies based on economic data. Economic data are statistics that – unlike market prices – directly inform on economic activity. Tradable economics is not a zero-sum game. Trading profits are ultimately paid out of the

Factor exposure analysis is essential for performance and risk contribution However, the results vary depending on methodologies, factor definitions, and other assumptions A holdings-based approach is preferable over regression analysis INTRODUCTION A large part of a capital allocator’s job is to

The inspiration for this post comes from a new paper titled Predictable End-of-Month Treasury Returns (h/t Capital Spectator). A description from the authors: We document a distinct pattern in the timing of excess returns on coupon Treasury securities. Average returns are positive and highly

Researchers love novel datasets–it gives them a new set of information to conduct studies and test theories. That brings us to this paper, titled “Core Earnings: New Data and Evidence” by Ethan Rouen, Eric So, and Charles C.Y. Wang. The paper uses a novel database created by our friends at

For this post, I want to take a look at the concept of intra-day momentum and investigate whether we are able to identify any positive signs of such a phenomenon occurring across (quite a large) universe of NYSE stocks. It has been suggested that, for the wider market in general at least, there is a

Let’s start with an experiment. We divide people into two groups, A and B. Then, we ask group A to guess how old Mahatma Gandhi was when he died, taking into account it was after age 9. And we ask group B the same question but taking into account that it was before age 140. Of course, the extra

Pairs trading is supposedly one of the most popular types of trading strategy. In this strategy, usually a pair of stocks are traded in a market-neutral strategy, i.e. it doesn’t matter whether the market is trending upwards or downwards, the two open positions for each stock hedge against each

Many famous investors are outspoken about their investment philosophies, and carefully apply them to a select number of securities. Who among us hasn’t thought if they could at least capture some of the talents of our favorite investors in a bottle, we too could be super investors? Turns out you

While the quality factor has been identified in the literature (including papers such as “Buffett’s Alpha,” “Global Return Premiums on Earnings Quality, Value, and Size,” and “The Excess Returns of ‘Quality’ Stocks: A Behavioral Anomaly”), and there are now a number of investment

Some bloke* once said "The most overlooked characteristic of a strategy is the expected skew of it's returns, i.e. how symmetrical they are" * It was me. "Systematic Trading" page 40 Skew then is an important concept, and one which I find myself thinking about a lot. So

Equity income mutual funds have underperformed the S&P 500 since 1988 Especially on a post-tax basis Investors can create tax-efficient equity portfolios, but it does not represent a free lunch INTRODUCTION Warren Buffett is probably the most well-known and well-liked investor, which is easily

After the Great Financial Crisis, the Momentum factor has exhibited positive returns, but those returns have been largely driven by the short side of the portfolio. One research note suggests that this is driven by increased risk aversion among investors, using the correlation of high volatility and

Most asset allocation approaches are more or less static. From 60/40 to Risk Parity, such allocations can be easily replicated with a couple ETF’s, and so the outcomes of static asset allocation portfolios, especially the risks such as drawdowns, are 90%+ pre-determined. There is a strand of

I have recently been reading about more modern ways to decompose a matrix. Singular value decomposition is a popular way, but there are more. I went down the rabbit whole. After a couple of “see references therein” I found something which looks to justify spending time on this. An excellent

Explaining the Demise of Value Investing Baruch Lev (NY University) and Anup Srivastava (U. of Calgary) August 25, 2019 The business press claims that the long-standing and highly popular value investing strategy—investing in low-valued stocks and selling short high-valued equities—lost its edge

The crowning achievement for investors is the ability to identify which of the few active mutual funds will outperform in the future. Despite an overwhelming body of academic research which has demonstrated that past performance doesn’t guarantee future performance and (as the annual SPIVA

Most of us focus our research time looking to find better entries. We don’t spend enough time thinking about our exits. I am definitely guilty of this. A popular way to enter a mean reversion trade is by using a limit order. I use that on the strategy on RSI2 Strategy: Double returns with a simple

What good is synthetic data for in a financial setting? This is a very valid question, given that data augmentation techniques can be hard to evaluate and the time series they produce are very complex. As we will see in this post however, it turns out that synthetic series can be very useful!

What is a crowded trade? What is asset centrality? Does asset centrality predict bubbles? Can it be exploited? What are the Academic Insights? In the normal course of events, investors perceive and act upon changes in fundamentals that will persist indefinitely (or until the next change in

In this blog post I wanted to run a couple of quick experiments to see how clearly I was able to highlight the importance of incorporating various elements and components into a backtest that I admittedly often overlook in most of my posts – that is I make the assumption that they will be dealt

Over the years I have posted about several different methodologies for creating synthetic data and I have recently come across yet another one which readers may find useful. One of my first posts was Creation of Synthetic Data, which essentially is a random scrambling of historic data for a single

One measure of the crowdedness of trades in a portfolio is centrality. Centrality is a concept of network analysis that measures how similar one institution’s portfolio is to its peers by assessing its importance as a network node. Empirical analysis suggests that [1] the centrality of individual

Research into the momentum factor continues to demonstrate its persistence and pervasiveness, including across factors. Recent papers have focused on trying to identify ways to improve the explanatory power and performance of momentum strategies. Prior research on Momentum The study “Momentum Has

Financial academics have described so many equity factors that the whole universe of them is sometimes called “factor zoo”. Therefore, it is no surprise that there is a quest within an academic community to bring some order into this chaos. An interesting research paper written by Favilukis and

A stop-loss order, or stops as is generally said, is an order placed with the broker to sell (or buy) if the stock of a company which you hold, reaches a pre-determined price in order to avoid large losses. In the trading world, the use of stops is seen as an essential part of risk control and money

As trading costs have just hit zero, and passive investing overtook active in August, the investment industry is braced for further pressure to deliver alpha after fees. In my view, the potential to build great models today is huge, but constrained by the research cultures of most firms. Here is

While it may be tempting to time allocations to active strategies, it is generally best to hold them as long-term allocations. Despite this, some research has shown that there may be certain economic environments where trend following equity strategies are better suited. In this commentary, we

Option-based strategies have similar characteristics to Low Volatility portfolios Combining these reduces idiosyncratic strategy risks The combinations feature higher risk-adjusted returns and lower drawdowns than the S&P 500 INTRODUCTION Some investment products and strategies can be considered
