  • How is the fair value of the stocks in the database determined?

The fair values in the database and the output values in the free self-service calculators are based on a formula that we developed ourselves. The formula is the result of years of statistical analysis and higher mathematics. First, we tested thousands of stocks for their true value. With more cumbersome procedures, companies could already be tested for their true value, much like company auditors do. From the results, we have derived a formula that yields nearly the same results, but brings many benefits.

  • What are the advantages of the Fair Value Calculator method compared to conventional valuation methods?

The Fair Value Calculator method requires no prior knowledge and is suitable for beginners. Within a short period of time, stocks can be tested for their true value and, as a result, a portfolio of equities that is likely to outperform the market as a whole. In addition, the Fair Value Calculator is free, which gives the user a financial advantage over conventional fund investments.

  • What does the comparison with the "total market" mean?

The total market is the sum of all price gains and losses of stocks. So the market is the sum of all stocks in a given area. If one takes the average return of own shares and compares it with the market, one can read off how skillfully the shares were selected. The goal is, of course, that your own shares perform better than, on average, all other stocks in the market. Let's talk about from the market or overall market, which means the average return on major stock indices such as DAX, Eurostoxx, Dow Jones, S & P 500, Hang Seng and more.

  • Why should I choose my own shares and not just buy an equity fund from my house bank?

Banks very often charge subscription fees and fees for the management of the fund. These fees are usually so high that these funds outperformed the bottom line than the market as a whole. On the other hand, if you invest yourself in an online account and manage your own shares, you save those fees and can more easily beat the market.
