December Seasonality In OBX (Oslo Stock Exchange)

Last Updated on July 7, 2022

Below you can find the gain each year from 1997 until 2011 in OBX. It’s divided into two: The whole of December and the 2nd half of December. The 2nd half is from the close of the 15th or the day before if the 15th was on a weekend.

OBX consists of the 25 most traded securities on Oslo Stock Exchange. It’s rebalanced twice a year. You can either buy/sell OBX as a futures contract (average turnover about 20 000 contracts a day), or you can buy an ETF which are fairly liquid (there are a couple of them, even with 2x gearing). Or you can try spread betting.

Worth mentioning is that Statoil, the former state oil company (they still own the majority), is weighted about 23% of the index.

Here are the results:

As you can see, only 1998 2002 and 2007 were troublesome for the whole of December. The second half of December is only down in 2002.

  • Seems like 2012 will damage both statistics…
    Personally, I’d never trade on seasonal trends like this. The reason is that everyone seems to have an explanation for why December “always” is a good month. And when everyone has an explanation for the same truth it’s time to trade something else.
    Do you agree?

    • I trade on seasonalities. It’s working pretty good most of the time. Of course, you never know when it stops working. This December it does not work pretty well. That’s ok, you can’t expect to win all the time. This is just 1 of many things I trade (currently I have 20 strategies, both daytrading and EOD).
