I actually meant to focus on the tape at hand today and get back into the swing of things on the trading front. However since my main Internet connection just went bust two hours ago I decided to use my connective idle time as an opportunity to talk about an issue many of you may have been battling with at some point or the other: Whether or not to scale into positions. Does it work? Should you do it? The quick answer (and you knew this was coming): well, it depends.
While I am taking some time off I thought I may as well repost some of popular educational posts which many of you may not have seen or completely forgotten about. The first one is from early 2012 and covers volatility and kurtosis:
If you run the math you will find that on a daily basis – annually – the skew is close to normal, and but KURT (i.e. kurtosis) is large. That is due to compounding error of the VIX distribution and overlapping seasonality data. But nothing is black and white – I believe in conditional statistics and offsetting tail distribution. Common sense tells us that when the VIX is > 25 the market will exhibit a different distribution [...]
Today I will introduce an aspect of volatility that you most likely have not seen being addressed anywhere else: realized volatility profiles. First up let’s make sure you all understand what realized volatility (RV) is and how it compares to implied volatility (IV). Simply RV measures the amount and amplitude of price change observed in a financial instrument over time. Big moves to the up side and down side will both produce spikes in RV. As such the volatility we measure or predict always produces an unsigned return – it does not care whether the market goes up or down.
I’m as surprised as you may be seeing equities head straight lower overnight. As you know I was actually positioned both long (ES) and short (NQ) expecting a break out after obvious signs of distribution. Things are clearly very confusing right now – yes, I phrased it this way intentionally. So let me explain what I mean, starting by talking about SKEW.
