Can I sell my shares of one stock and immediately purchase shares of another stock?

Only new investments will go toward the purchase of a new stock in your Custom Portfolio. If you remove a stock from your portfolio, then the shares will be sold and sent to your linked bank account. Any stocks added to your portfolio will require a new investment to prompt the purchase of those shares. 

Selling stocks or ETFs may create a taxable event. If you have questions about your personal tax treatment, please consult a tax advisor.
