Kris Longmore 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, I’ll use some of 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 seek …
I felt like doing something a little more lighthearted than usual. I’ve been deep in data engineering land these last couple of weeks, building data pipelines for processing a ton of options data for a trade we’re researching (the straddle-over-earnings trade). So I took some time out to mess around with something fun – building a …
I want to discuss a couple of simple trade-off considerations around quant trading signals that may not be obvious. Here’s the price of some asset: Our main job is to predict how it’s likely to move. To do this, you use information about it that you think is predictive. And at any point in time: …
Traders typically have many ideas for trading strategies – more than they can ever implement in practice! Therefore it’s useful to be able to move quickly in the early research phase. You want to disprove things as quickly as possible so that you can move onto the next thing. Obviously there is immense value in …
In 2021, James, I, and a small team decided to set up a crypto trading venture. We faced several problems, but knowing almost nothing about crypto was the most significant. We sensed that the fractured, developing nature of the crypto market would likely be a good place to seek out inefficiencies, but beyond that, we …
When you do anything with data, you should think about the intuition of each thing you do, and what it represents “in the real world”. Let’s take the example of log returns, which some people tell me they find confusing. Consider an asset whose price goes from $100 to $200 Assume there are no other cash …
In this blog post, I will demonstrate how to work with stock price data using the DuckDB database management system in R. DuckDB is a fast and lightweight analytical database engine that is designed to work with various programming languages, including R. You can use Duck DB from the command line or from a client …
Alpha isn’t just about finding people willing to trade at bad prices. Although that’s a necessary condition, it’s not enough. We also need to know why people are willing to buy too expensive or sell too cheap. The reasons are pretty simple: The first reason requires the existence of other uninformed traders, or what some …
dplyr 1.1.0 was a significant release that makes several common data operations more syntactically intuitive. The most significant changes relate to joins and grouping/aggregating operations. In this post we’ll look at the changes to joins. First, install and load the latest version of dplyr: install.packages(“dplyr”) library(dplyr) A new approach to joins The best way to …
