Are you totally ignorant of how economics and the stock market work? Let me explain why your numbers are misleading.
First of all, the internal rate of return (IRR), that you are using, is a metric used by businesses for capital budgeting for future expansion. IRR is a discount rate that makes the net present value (NPV) of all cash flows from a particular project equal to zero.
Once the internal rate of return is determined, it is typically compared to a company’s hurdle rate or cost of capital. This is not something you do for equities as it ignores net income as an asset.
For equity investments, Accounting Rate of Return (ARR) or sometimes called the Annual Rate of Return is used. ARR is the average net income an asset is expected to generate divided by its average cost, expressed as an annual percentage. This is the de facto method for comparing the performance of investments with liquidity.
By your logic, using IRR for investments would mean that nobody would buy bonds or any fixed income product since the IRR would be zero as the undiscounted price per share doesn't change. You can not ignore the total income generated by an investment.
Next, when comparing Obama's economy to Trumps it is also necessary to look at the big picture. Trump has achieved the Lowest unemployment in decades, higher job growth than Obama, higher wage growth than any time during Obama, higher GDP than any time during Obama and higher than he said could be reached, the highest percentage employed since 1960, and the highest stock markets indices in history.
Trump's job growth may falter a little going forward as companies are starting to have a hard time finding qualified workers, though this may translate into even higher wage growth.
Now some other facts about how well Obama did.
Obama is the only President in history to have an average annual growth rate of just 1.46%. the overall weakest of any expansion since 1929. Obama's "recovery" has officially been called the worst recovery in US history according to Forbes Business.
Obama is the only President in history to not have one year of GDP over 3%. Every other president in American history, even the really bad ones, (of which he is the worst) had at least one year when U.S. GDP grew by at least 3 percent.
Finally, using ad hominem never helps your argument. It only shows a weak argument from a weak mind.
