(1 + yield)^t = gain where t = time, gain is final value divided by initial value, and yield = gain per t

where t = time, gain is final value divided by initial value, and yield = gain per t solving that for yield, you get yield = 10^(log(gain) / t) - 1

the values in the plot are then 10^(log(final value / initial value) / (years in office)) - 1

It's unclear who should get credit for the performance during the first year of a president's term. I was curious how that changed the numbers, so the table below has the annual yields using actual term, and using 'one year after start of term to one year after end of term'.
