<prompt> Human: A bit of back story: Ive been working at bigNameTechCompany for the past few years and putting their maximum match into my 401K and also deducting the maximum contribution for their ESPP. This leaves me with maybe 60 of my gross pay after taxes actually ever hitting my bank account which makes it difficult to save more than the 50month required by my bank to avoid fees on the savings account. The good news is that the ESPP is actually very good, and gives us the stocks in periods of 6 months, with our contribution for the past period being used to purchase stock at 75 of the lowest value it has been during that previous period. The funds go into ETrade and Ive just let them sit there and have had dividends automatically reinvested. Because ETrade is pretty good about getting funds transferred to external accounts pretty quickly, from what Ive heard, Ive been treating the funds in the ESPP brokerage as an emergency fund. Even if I had to pay the immature investment tax of taking out the money prior to 4 ? years it would still cover 3 months of my current income. Im still living the cushy life of a student with state scholarship for now and have never really considered this being a potential problem.Is this the worst idea ever? What advice do you guys have for me?  <response>: No. That would make your e-fund subject to market changes and that kind of defies the point of it.
