Say I found a time machine and decided to go back 20 years in time replacing my past self while retaining my current memory then sell my house (which is my largest asset at that time) and invest in 1 particular company using my entire savings, for example one of the current large tech companies like Google or Facebook.
Would the fact that I did this have a big enough perturbational effect on the new timeline to cause said company to not end up being as successful as it currently is? This is with the understanding that the company was profitable in this timeline where I did not invest in it, and that complex systems can be unpredictable in their evolution i.e. the butterfly effect.
Alternatively what is the safest way to make a profitable investment in an uncertain commodity having foreknowledge of its success in other timelines?
