Someone has published some Python backtesting code that claims to have made 8371% profit.
Can some experts here analyse/verify/confirm/comment it? :

I have even a better strategy, buy Amazon in 1997 for $0.1 and sell it today for $155, 155000% profit babe! You can pay me $1000 for more stock tips

Just make a time-travel back to 1997 and buy the stock.
But you would end up in a different timeline than this one...
