Quote from MGJ:
Your best source of advice is: YOUR INVESTORS
Ask them.
Be completely honest. Tell them: "I have no bloody idea how to invest this $50 million, what do YOU think I should do?"
They will admire you for your honesty and humility. They will also surprise you with the sagacity of their recommendations and advice. After all, they didn't accumulate $50 million of risk capital by being stupid. LISTEN to what they say and give it due consideration.
These millionaires (your investors) hired you because of your expertise and your above-the-crowd knowledge ("alpha") . When you admit that you have none, and that you need help, they will find it endearing and encouraging. Ask the millionaire experts!
Leverage the resources you've got! Very few people have access to the kinds of insiders that your investors represent -- treat it as an Unfair Advantage.
