There are a slew of things that were going on that make it much more probable than you might realize. One non-mathematical factor was that oil was already spiked, the perfect time to short is when it's on the rise, especially with intent of a mean reversion trade. You don't short oil on the trough's, you short on the spikes - the probability of a short working that day was much higher than average. Next, there are definitely ML algorithms running in prop shops as we speak that are trained on the probability of DJT and media announcements, especially in volatile weeks like we've had. I cannot post the data here, but there is an article on Axios that shows this:

So not only was a mean reversion probability high, but there were probably prop shop ML algo green lights going off for the probability of an announcement that would give the mean reversion some more fuel. Regular algorithmic trading shops probably added to this volume when their programs saw larger orders coming in, which made the volume spike even larger. Lastly, Nick Marsh is a journalist, not a professional trader or a professional in algorithmic trading. If he was, he wouldn't be making shock and awe articles for the BBC. For one low hanging fruit, why did he not pull historical data on oil futures - including other derivatives (not only Brent)? He would have needed to pull at least several years of data to understand if this was an actual outlier spike or not. If you have ever even remotely paid attention to the oil futures markets, you would know there tends to be higher volume spikes at any given time, especially after the futures market closes and re-opens between 5 and 6pm, and especially during volatile times like the last couple months. This article isn't the full picture at all whatsoever and comes from someone who has an elementary understanding of the equity and futures markets. But it served its purpose, which was triggering an easily triggered society. Surely there has been some DJT-linked insider trading, but I personally cannot jump on board until there is more evidence - AKA the scientific method. |
