<prompt> Human: My net worth according to Mint, which includes unvested stock: 60,000 cash 60,000 retirement account 90,000 vested RSUs in my employer. 320,000 unvested RSUs in my employer.Im working on getting the cash into an index fund VFIAX; I opened a Vanguard account yesterday, and now Im thinking about the selling the vested RSUs to add to that index fund. Currently, the only investments I have outside of my retirement account are in the company I work for.But I strongly believe in the future of this company. Wall Street is bullish on the company too and part of that is baked into the current price. The current market cap is 6B with a revenue of about 500Myear. I believe they will be at 4Byear revenue within 5 years.But everyone talks about diversifying and hedging risks. Those risk management folks seem to afford nice suits. And rationally it makes a lot of sense, except I feel like I have inside info by seeing the inner workings culture of this company, and so I can be even more bullish than the Wall Street number crunchers that are limited to financial disclosures.So, should I play it safe by moving the vested stock to an index fund, or trust my insider gut that this company will out-perform the market?  <response>: 78 of your net worth is in a single equity. Not only would you lose 78 of your life savings if something bad happened to your employer, but you could lose 78 of your savings at the same time as losing your job.Yes, you should diversify. How much? You dont have to diversify all of it, but figure some safe percentage. P.S.: Wall Street is bullish on the company too and part of that is baked into the current price. Doesnt leave any upside for good news, and all the downside for anything less than good news.
