This paper tests if the use of simple technical trading rules on Swiss stock prices is profitable. It considers several trading rules based on the crossing of moving averages. The use of bands and oscillators such as the relative strength index or the stochastic indicator is also investigated,...

This paper presents a simulation of a global investment strategy that combines diversification and option strategies, in particular the covered call strategy, on the Swiss Exchange.
