<prompt> Human: Im particularly worried about the tax implications of transferring over all that money at once. Will I have to pay capital gains tax? If so, how do I determine how much I will have to pay? This is my first time handling this amount of money and advice would be greatly appreciated!Edit: As people have mentioned, it seems like Fidelity also offers low-fee index funds, so I would be fine with keeping the money with them. I am more concerned with how to manage the taxes that will come from selling these stocks in order to invest in an index fund.  <response>: Given how? Inheritance? Or a gift?What type of account is it? Tax advantaged? Taxable? Im surprised people are giving you responses without knowing these answers.
