The thing is you don't know whether if that 1 share is going to move it up or down. Might as well just buy lotto. Risk is so small and the lightening strike payoff is much bigger!
BTW, Federal Reserve suffered a massive disruption to it's payment services today. Yes, the heart of our economic engine essentially had a cardiac arrest for few hours today. Is it because it ate too many greasy burgers? Inherited this heart problems thru its genes? Covid19 infection?
My guess is that it was hacked. US is just not very good at cyber security.
Makes me want to invest in some crypto-currencies or gold...
