I agree with Charlie, but a few points to consider--

1. Some advisers associated with brokers are known to churn an account to generate additional commissions. So part of this is your confidence that the adviser is acting with your best interest in mind.
2. Some do note that the markets are up with the Dow close to setting records. They expect a correction. If you have cash available, you will be able to take advantage to accumulate shares at perhaps a discount of 5 to 10% from current market prices. We hope recovery will be quick. Hence, it can be an opportunity for fast profits.
3. Some stocks that have reached their potential or even exceeded targets can be ripe for harvesting. You will want to consider tax implications if in a taxable account. Are they long term? How much longer must you hold them to get to long term?
