When it comes to investing, I love thinking in terms of standard deviation. It’s one of the quickest ways to assess the risk of a potential investment, and there is an established good benchmark standard deviation that I shoot for when picking investment strategies. There is just one small problem – the close. Statistics, though one of the most helpful maths in the investment world, is rife with biasedness. Whether that biasedness is intentional or not, it’s still a big problem. One such parameter that is heavily influenced by this bias is Standard deviation.
