<prompt> Human: TL;DR Sell freediscounted single stock immediately and put in high interest savings or leave it in the market? I participate in an Employee Stock Purchase Plan at work as well as receiving annual stock grants. The ESPP is nice in that youre purchasing the stock at a 15 discount off the stock price at the beginning of the offering period. Stock value has doubled since the IPO but Ive noticed it never really stays above 65 a share for all that long. The stock in question is TMUS. I am considering selling and moving the money into my 1.3 interest savings account. That way Im always gaining, just in the form of interest. I do not have enough of a deposit to go into a money market yet. Is there any reason why I should keep my single stocks in the market?  <response>: You should sell employee stock as soon as they vest and use that as cash available to spend or invest as per your larger goals.
