<prompt> Human: New to straight stock buying, investing wise I only have a virtually unattended Roth. Im starting a new job soon and will have the opportunity to take advantage of 15 discount in the employee Stock Program. Details from them about the program: Participants purchase stock by contributing 1-10 of their pay with after-tax payroll deduction which I assume is better than basing it on gross. Two open enrollment periods each year 1st-15th of May and Nov. The company itself was founded in 97, but only went public in mid 2014. Its a relatively small, but growing company of about 2000 employees. Ill post a links of the stock history and info that I have no idea how to interpret, form the only finance website I am familiar with sorry if yahoo finance sucks.  <response>: I buy into my companys ESPP at a high percentage because we get pricing based on the higher of two points opening and closing of a 2 year enrollment period plus a 15 discount.As soon as my stock is available, I sell it and pay capital gains. Its basically free money since you can never make less than 15 over your invested salary. Just dont hold your own companys stock for long.
