Hey now!
Your board host is the GOAT! 
Without dabbling in currency trading, shorts, futures, etc etc. 
Still 30% over 30 years does wonders beyond imagination to a portfolio of almost any size.
I guess if you are a billionaire, you now have no choice but to hold big chunks of Amazon, Mr Softy, Salesforce, etc.
Thankfully, we can buy the real disruptors, your Zscalers, AYX, TWLO, TTD, etc etc.
Best,
Matt
