A stock market broker lists a stock with an expected growth of 8.17% and a margin of error of +3.83%. What is the minimum expected growth percent for that stock?

The margin of error is ± 3.83%. If the stock is 8.17%, it means that the minimum expected growth would be 3.83% below 8.17% and the maximum expected growth is 3.83% above 8.17%
Thus, the minimum expected growth is
8.17% - 3.83%
= 4.34%
