Today, we’re delighted to welcome Mark Rzepczynski onto the show to discuss his time working with John W. Henry and what J. W. Henry’s ‘secret weapon’ was, the most effective way to gain downside protection, how to overcome behavioural biases in investing, how diversification can reduce profitability during huge trends, how to effectively make the case for Trend Following to potential investors, where returns dispersion among CTAs is stemming from, and one of our favourite topics: how many markets in a portfolio is too many?
