Episode 42 – Laurens Bensdorp - Building Strategies with Purpose

There’s a special place in trading graveyards reserved for the back-test that looked gorgeous on paper and then detonated in production. I’ve been there. If you trade long enough, you will too. We all know the over-fittings issues, and I’ll get into that, but there’s another reason why back-tests can fail: the initial purpose is not matched to the right method. If we ask the wrong thing of the test, measure it with the wrong yardstick, or ignore how strategies behave when they’re combined (not consider portfolio impact), then failure is likely. Laurens Bensdorp has a major focus on this – nicely summarised as building strategies with purpose.

035 - Bob Pardo Part II - Building Trading Strategies that Work with Walk Forward Analysis - Part 2 of 2

I had a thought this week about what constitutes my "trading edge". You know, the question every trader is expected to be able to answer. It's supposed to constitute some kind of evidence that you can out-perform the market, your peers, or whatever. Something Bob Pardo mentioned made me think differently about this when he reminded me that when trading pits were around, every trader "had to have their edge" to stay ahead of the other guy or gal. Back then, on the floor, it was necessary to have some kind of "insider knowledge" so to speak in order to carve out success.

In this episode, seasoned trader Rob Carver shared his nuanced approach to building and managing a diversified futures portfolio—a methodology that appeals to advanced, technical traders, while we also covered off some of the 'basics' of futures trading, such as rolling, back-adjusting, and so on.

032 - Dr Ernest Chan - The Breakthrough Uses of Machine Learning in Risk Management

It was strangely comforting talking to Ernie Chan. Whilst I was completely out of my depth talking about AI and Machine Learning, I came away broadly reinforced in my own belief that great trading still requires a human touch, and that the best niche's in the market are best discovered by applying a certain kind of wisdom, experience and competitive approach. The machine learning techniques and computer power needed to make them work are, however, quickly catching up, so how long we have is anyone's guess.

029 - Jason Buck - Mutiny Funds - Building a Cockroach Portfolio

The concept of the “Cockroach Portfolio” is a novel take on building a robust investment strategy that thrives across diverse market conditions. Drawing inspiration from one of nature's most resilient creatures, this approach emphasizes adaptability, diversification, and risk mitigation.

Defense wins championships.” Mutiny’s version of a diversified, all-weather portfolio therefore combines defensive-minded strategies, such as long volatility and trend, with offensive-minded strategies, such as stocks and bonds. Ensuring survival, and reducing draw-downs through time, provides the best opportunity for long-term capital growth. This show is all about risk management.
