Directors’ dealings and the 200-day simple moving average
October 23, 2024
In an earlier blog post, we showed that linking managers’ transactions with selected technical analysis indicators improves replication performance especially in timeframes of a few weeks to a few months. The 200-day simple moving average (SMA) is used to evaluate long-term market trends and the stock price above/below is considered a positive/negative signal.1 Consequently, this leads to the question: Can the combination of directors’ dealings with the 200-day SMA improve replication performance in the longer term? To answer this question BOSS STOCKS evaluated 120+ directors’ dealings (stock acquisitions) in the German DAX between January and mid-October 2023.

Combining directors’ dealings with the 200-day SMA boosts replication performance in the longer term
- The results show that replicating directors’ dealings is successful even with a simple strategy: Buying stocks for the opening share price of the day that follows the day of the release and holding for 1 month/3 months/6 months/1 year led to average investment returns of 2%/3%/7%/14%.
- Focusing on managers’ transactions above the 200-day SMA further bettered the investment returns for 1, 6 and 12 months. Finally, the increase (+7 p.p.) is largest for 1 year. Moreover, the only timeframe for which the combination does not lead to improved investment returns is three months.
- Across all timeframes, the variation of values around their mean is lower above the 200-day SMA. This is in line with a previous blog post. The replication of managers’ transactions above the 200-day SMA might be more suited for risk-averse investors.
- The highest investment returns north of 100% over a period of 12 months are all attributed to directors of Rheinmetall.
