Sweden and OMX is a good place to invest
Contrary to what many believe, Sweden is not as socialistic as many believe. Sweden has a long history of being capitalistic and has a very innovative economy. As a result, it has performed better than the US stock market since 1965:
The table above is taken from Triumph Of The Optimists written by Dimson, Marsh, and Staunton. The returns above are real returns. As you can see, the Nordic countries have all performed better than the US market!
Sweden OMX trading strategy
But this article is about trading, not long-term investing, so let’s go ahead and look at one example of a Sweden OMX trading strategy. We used to trade OMX futures but we stopped a few years back to narrow our focus to other futures markets. One of the reasons was the time zone. We are based in Northern Europe, but we also trade other EU products in addition to the US markets. To narrow our focus and work we decided to skip OMX.
Sweden OMX trading strategy backtesting
The backtests done in this article are based on the cash index – NOT the futures. Thus, the results are only indicative!
If you backtest the OMX futures you might get very different results (the shorter the time frame the more different results). The best way to learn about the differences is to actually backtest BOTH the cash and the futures and you’ll experience it firsthand yourself. Trading is all about trial and error!
Sweden OMX trading strategy no 1
We start with a trend following strategy: we use the classic 200-day moving average strategy where we buy a cross above the moving average and we sell when it crosses below. This simple strategy has returned the following equity curve:
The Compound Annual Growth Rate (CAGR) is 3.5% which is substantially lower than the buy and hold of 6%. However, the strategy is only invested 34% of the time and the risk-adjusted return is over 10%. For more info about the latter please read our article on strategy performance metrics.
Sweden OMX trading strategy no 2
Let’s go on to backtest a mean reversion trading strategy. This is a type of strategy that has performed well on most developed stock markets over the last 30 years. Does it work on Sweden’s OMX? There is only one way to find out and that is by using backtesting.
Below is an equity chart showing where we buy a low Williams %R reading and sell when the readings goes above a threshold with a higher reading:
The average gain per trade is 0.55% and the trading win ratio is 74%. However, the strategy has performed poorly since 2017. We backtested many other mean reversion indicators, and they confirmed the same pattern: mean reversion has deteriorated over the last years. Is this temporary or a long-term trend? Only history can tell. This is what makes trading so challenging!
Sweden OMX trading strategy – ending remarks
Sweden has a huge capital market and the liquidity and trading opportunities are high. A lot of capital has accumulated in Sweden over many decades.
In this article, we backtested the most traded instrument, the OMX 30. Unfortunately, in our opinion, it has become trickier to trade the OMX over the last five years. The OMX trading strategies we backtested confirm that, especially when it comes to mean reversion strategies.
