Who is the Best President for Wall Street?

Hello guys,
from this one we'll make some political-economical post.
Today we want to answer to this question: who is the Best President for Wall Street?

We use a mathematical approach… It’s very simple but efficacy and objective…

We evaluate the Best President with the performance of Dow Jones Index. These are the steps:

1# Calculate the returns using this formula:

Return = (Price at the end of the presidency – Price at the beginning of the presidency) / Price at the beginning of the presidency

The start value is 100.

2# Represent performance graphically:

This performance study makes it possible to determine if a “President A” is stronger or weaker than “President B” and to make a ranking list.

The best President is Calvin Coolidge, with a performance of 364.17.
The worst President is Herbet Hoover with a performance of 17.15.
