Oh wow this comment blew up, a bit. Not a regular here so did not see until now. A few additional comments if it matters: 1. Not everyone is a boglehead (well diversified every single minute of life). People do remain married to the company they work for. Even if it is 20% of high earners, it is a big number for bay area. 2. Even if you wanted to be diversified, the lessons of Enron and 2008 are too old for many. So you sell GOOG and invest in ... Netflix? Amazon? Facebook? NVDA? In the leading companies of the past decade, you traded one devil for the other. Even without insider product knowledge, you do not want to move away from your thriving neo-monopolist. 3. People do diversify but in small numbers. It is anecdotal data but people would have a million in vested RSUs and they will diversify only 50K to 100K because the fear of taking wrong decision is too great. 4. Many people do diversify from their RSU into housing. There are people (not me) who own 3, 5, 10 houses. For someone owning 3 houses (bank still owns it, but they have rent > payments), the utility of stock diversification is very small, and the next time they accumulate enough RSUs to buy another house, they do. As someone said, most of the banks have added on RSU specialists to amortize the unvested RSUs over the next 4 years and show that income as income that could be used to qualify. Of course, this is the outcome of the last 10 years of low interest regime. And of course there are many people who do differently, but believe me there are enough people with 6 figure vested RSUs which apart from their house is the single biggest investment they have and they live(d) lucky : until the recent market hiccups.
