<prompt> Human: So I just moved almost all my mutual funds from American Funds to Vangaurd and am so happy with my decision. Within just one week I noticed the balances increased 150. Now if I am in need of extra cash would it be a bad idea to take out 150 rather than re-invest? What kind of effect does this have on the long-term growth of my money.This particular account is not in an IRA or Roth, it is just my savings.  <response>: Re-invest isnt really even the appropriate term here, as your shares have simply increased in value. Yes, if you need cash, you should sell some of your mutual fund. But honestly, this question is a sign of a problem: You dont have a cash emergency fund? You should really keep at least three months worth of expenses in an emergency fund. How would you feel if your mutual fund lost half of its value over the next few months? That would leave you high and dry.
