Gains on then Gains
The real magic is “time in the market” and the effects of compounding, or the “gains upon the gains”, during full investment. The well-known formula shown below should be your guiding principle, not the random news of the day.
%Gain = 100 x (1+i)^n
where i is the “interest rate” (or growth) of your investment over a certain period and n is the cumulative time invested.
The chart below shows the true magic of compounding over a 30-year period with three different “interest rates”. One can see that the effects are more pronounced in later years.
