In this webinar, James explores a simple seasonality effect and finds that there’s more to the story than an upwardly sloping equity curve. Watch the video to see how you can use Excel to explore market phenomena efficiently and gather evidence that you can use to make practical trading decisions. If you’d like to master …
Having the ability to call bullshit on market claims is a superpower. There’s some ancient trader lore that says it’s a bad idea to hold SPY when it’s under the 12-month moving average of its price. Is there anything to this idea? Check out the webinar below to see how we put this idea to …
Having a reliable source of free data is extremely handy for the independent trader. It allows you to move fast and look into your ideas quickly. Yahoo Finance recently changed how you can access their historical stock data. No more simple downloads from the website and programmatic access now requires a different approach. For the …
Ever met a quant who was slightly religious about their tools? I’ve had Python zealots, R devotees, and MATLAB missionaries (well, back in the day, at least) all claiming their way is the best way. I use R for most of my analysis. The tidyverse libraries make sense to my brain, and I can move …
UVXY is an ETF that targets 1.5x the daily returns of a 30-day constant-maturity position in VX futures – the SPVIXSTR index. Before 2018, it targeted 2x returns – but Volmageddon ruined the fun.

People often ask me for book recommendations. But here’s a better question: What’s going to help you make money today? Reading a book probably isn’t the answer. I’m not saying books aren’t useful. They absolutely are. But you’re not preparing for a PhD defence – you’re trying to turn money into more money through trading. …
In this article, we’ll use simulation and simple visualisations to build intuition around how different variables drive the price of an option. Building this intuition is important because it helps you react quickly and make decisions without relying on complex pricing models. Let’s get to it. The value of a call option at expiration A …
Back in May 2020, in the eye of the Covid storm, we looked at overnight vs intraday returns in US equities. Intuitively, we’d probably expect to see higher average returns overnight when the market is closed – because it’s much more difficult to hedge and manage our exposures when the cash market is closed, so …
Last week, we looked at simple data analysis techniques to test for persistence. But we only looked at a feature that is measured over a single day – the absolute range. Such a feature makes it easy to test persistence because you don’t have the problem of overlapping data. Each data point is entirely self-contained …
Here’s a thing that I suspect will make money, but that I haven’t yet tested (for reasons that I will explain shortly): Every day, at the start of the trading day, get the SPX straddle price and convert it to an expected SPX price move. Then at the end of the trading day, take the …
