Problems surrounding Evergrande, the Chinese property development company, are causing unrest in the stock markets. On top of this, October has also begun - the month that has a particularly bad reputation for traders!

Is that bad reputation justified?

October - the most dangerous month?

The table below shows you the 20 strongest daily declines in the Dow Jones. Now, take a closer look at the extreme movements I have marked in red. These are the cases that occurred in the month of October.

As you can see, 9 of the 20 sharpest declines took place in October. That is way out of proportion. Clearly October has a tendency to have a lot of sharp price drops.

Extreme courses are also real

In contrast, the situation was quite different in the first half of the year: in those 6 months there were only 2 out of the 20 sharpest declines.

So, October's bad reputation is not unfounded.

However, apart from the extremes, how does October perform on average?

October runs sideways

To examine this, let’s look at the seasonal chart of the Dow Jones over an extended period. Unlike the usual charts, a seasonal chart does not show you the price over a specific period of time. Rather, it shows the average trend over many years depending on the season. In this instance, mean values are formed from the prices of 124 years. The horizontal axis of the chart shows the time of year, the vertical axis shows price information. The chart therefore shows the typical seasonal price trend at a glance.

As you can see, it is in fact September, and not October, that is the weakest month. The latter in fact runs sideways overall (although admittedly this is below average).

October's bad reputation therefore stems from particularly strong declines, which actually occur more frequently in October. They affect individual days, but can also have an impact on the entire month.
