Actually by that time it was all employee purchase program (EPP) stock. You could put up to 10% of your post-tax income into a plan that every 6 months would buy stock at either 85% of the market price, or the &#x27;lock in&#x27; price, which ever was lower, and the lock in price was set the first time you started the program, held for 2 years and then reset each 2 years after that.<p><pre><code>   &gt; What would your advice be to people who hold most

Diversify. Especially if you are continually getting more of that stock (like RSUs or other options vesting). That is hard if you&#x27;re not public and there isn&#x27;t a secondary market.<p>A lot of people I knew in the dot com boom sold their stock and bought houses. That converted a fluctuating value asset into something they could live in regardless of its &quot;value&quot;. They looked like geniuses in 2001. When we sold the company I had helped start I took a chunk of the proceeds and put it into a separate account to help my kids college education. (it wasn&#x27;t a 529 but simply a named account that my financial planner helped set up).<p>Doesn&#x27;t have to be fancy, putting proceeds into and S&amp;P500 ETF is simple, low cost, and the S&amp;P 500 has out performed a lot of single company stocks. (and underperformed some to be honest but you are trading future value against risk).
