Shownotes

'When you look into history, so-called derivative investment products that you think of as being recent, actually go back to 2400 BCE, in various forms. Call options go back to 600 BCE at least. In the 18th century BCE there were personal loans, as well as a liquid secondary market for these promissory notes. So what we think of as new inventions are actually very old.' - Steve Foerster

If we could gather all of the famous investing pioneers from world history into one room and ask them to build the perfect portfolio, what would it look like?  Well Steve Foerster and his co-author (and previous guest on the show) Andrew Lo, set out to do just that, with their new book called 'In Pursuit of the Perfect Portfolio'. I thought I'd invite Steve onto the show to discuss his new book, go through some of the 'golden threads' of investing that he came across, his journey in the world of finance, and of course, get his opinion on how close Trend Following is to 'the Perfect Portfolio'.

Thank you for listening and please welcome to the show, our guest, Steve Foerster.

'The insight that Sharpe picked up on was, 'what happens to a model if we add one more security, and this security was a risk-less security? It turns out that this was the tangent that led to the optimal portfolio.’ - Steve Foerster
