This essay elaborates on some basic principles and investment strategies that have been proposed to reduce the effects of emotions and biases, and foster rational decision-making.
In the first part of this paper, I will summarize some of Weber’s findings on how humans are influenced by emotions and biases when interpreting information and making decisions. The second part will focus on how (i) reducing trading to a minimum, (ii) diversification and (iii) aiming for the market return can help to control personal biases in investing.
Investing money provides great opportunities, but also bears great risks. The market is unforeseeable no matter how much experience you have or how many books you read. Consequently, there is not the one right thing to do in order to be successful. However, there are some guidelines that can reduce your personal risk, help to control personal biases and make our decisions more rational.

Excerpt from the Book
3.1 Reducing Trading to a Minimum
Every time you buy or sell a security on the market, trading costs occur (e.g. commissions, slippage or the bid/ask spread) which reduce the returns from an investment. Thus, more you trade, the higher are your transaction costs.
On the other hand, time has shown that the long-term development of securities is generally positive. This may not be the case for every individual stock, but the value of a well-diversified portfolio, spread over different industries and geographical regions, has proven to increase in the long run. For example, the DAX index (consisting of the 30 largest German companies) generated an average annual return of 7.3% between 1964 and 2014 (Deutsches Aktieninstitut e.V., 2015). Similarly, the Euro Stoxx index (consisting of the 50 largest and most liquid stocks in Europe) has earned an average annual return of 7.3% between 1986 and 2015 (Deutsches Aktieninstitut e.V., 2016).
By limiting trading to a minimum, an investor can reduce transaction costs and benefit from this positive long-term trend of the market without risking to be misled by emotions to trade stocks at an unfavorable time.
