      Calculation problem that I will illustrate with Nestlé and Implenia:

      Nestlé earned 1972% in 29 years (excluding dividends). So we say that the average annual return was 1972 / 29 = 68% per year.

      For Implenia, the average return over the last 11 years (listed on the stock exchange only since 2006) was 167 / 11 = 15.2% per year.

      We realize that this calculation is absurd because the result is very strongly impacted by a long duration, because of the ever-increasing influence of the compound effect over the long term.

      In reality, Nestle's annual return should be around 10-15% per year without taking into account the compound effect. And this figure is in my opinion much more "true" than the 68%, because it shows what annual gain a NEW investor can expect to obtain.

      Hence my question: is there a formula for calculating the annualized return excluding the compound effect?

        Yes it's easy it's the CAGR or average annual growth rate in French

        A simple way to calculate it:

        Personally, I prefer to use Excel:

          Fantastic, thank you!

          If I calculated correctly, this gives us a CAGR of 11.02% for Nestlé and 9.34% for Implenia.
