RE:Oil watcher. Be very concerned!!!What they sold were rsu don't put too much thinking about that read this:
Holding the RSU shares after they are vested is the same as the employer giving you a cash bonus and you decide to use the bonus to buy the employer’s stock. It works only if you believe the employer’s stock will do better than the market and all other alternatives.
Besides the issue of being undiversified and having too much tied to your employer, just from a pure investment’s point of view, if you are going to buy a stock with the bonus, you can buy whatever stock you want. Is the employer’s stock really the best in a universe of thousands of stocks? Unlikely.
Therefore, always sell RSU shares as soon as they vest. If you are not contributing the maximum already, increase the contributions to the 401k plan, or fund a traditional IRA or a Roth IRA. Otherwise put the money into a diversified portfolio in a taxable account. Don’t hold the RSU shares.
