Opposite, when the distribution is negatively skewed, both the mean and the median is less than the top (the mode).ĭoes negative and positive skewness relate to trading? Yes, because negative skewness has the potential of ruining you. When a distribution is positively skewed, it means that both the median and the mean are greater than the top of the distribution curve (the mode). The difference between a negative and positive skew can be illustrated like this: We have previously written an article that covers negatively skewed trading strategies. Watch the trader who makes consistent money. Negatively skewed vs positively skewed distributions Opposite, right tail risk (right fat tails), are unexpected positive outcomes. Hence, it’s frequently referred to as left tail risk. If we look at a probability distribution, the unwanted tail risk is normally on the left side of the distribution curve and happens more frequently than a normal distribution suggests. Hence, tail risk is something that is rare and seldom and “hidden” in the corners (the tails).

This is what Taleb writes in Skin In The Game” about tail risk:įor, as with financial traders, the best place to hide risks is “in the corners”, in burying vulnerabilities to rare events that only the architect (or the trader) can detect – the idea being to be far away in time and place when blowups happen. But statistical studies of financial markets indicate “freak events” have fat tails. Any Monte Carlo simulations of sets of coin tosses are less likely to deviate from the long-term mean of a 50% chance for head or tail. Why? Nassim Nicholas Taleb, the author of The Black Swan and seen as the mastermind behind the philosophy of tail risk, argues that random huge movements in the financial markets happen more frequently than the normal distribution indicates.įor example, 1000 coin tosses are a perfect example of a normal distribution. We can argue that fat tails are a more realistic outcome of an event. But the fat tail distribution might indicate otherwise and subsequently, the trader underestimates the risk he is taking. If a trader or investor uses the blue line as the expected outcome, he might be filled into believing the risk is much lower than it actually is. In order to better understand the concept we made a chart to explain the difference between a normal distribution (bell curve) and a fat tail distribution: Tail risk is often referred to as “ fat tails“.
