<prompt> Human: Hi all. My grandmother recently passed away, leaving her estate to be split among my family and a local charity. The bulk of her estate is in the form of private stock in a regional bank, which she and my grandfather bought many decades ago. The stock has performed very well historically, having made it through the 2008 financial crisis without taking a hit. It also pays a sizable dividend to the shareholders.x200B;So now the beneficiaries are left with the decision of whether to hang on to the stock, or to sell the stock and diversify. Ive been sent a waiver by the estate lawyer that would allow me to keep the stock, since otherwise the fiduciary duty of the trustee would be to sell it and diversify. My shares are valued at about 400,000, and pay a divided of about 3,000 per quarter. I feel like this decision is a bit over my head. Part of me wants to trust that the stock will continue to perform well and it would be great to have the extra income from the dividends, but the other part of me is worried about the risk of holding a large amount of one stock. I know this pretty much comes down to how much risk I am willing to accept, but I wonder if any of you have any words of wisdom. Thanks in advance for your responses!x200B;Edit: Thank you to everyone who has responded so far. Now that I take a step back from the situation, I see how foolish it would be to hang onto all of the stock. Time to diversify!  <response>: You basically won the lotto. You can either continue to play high risk and stick with one stock, or diversify and protect the huge sum you already have. No need to be greedy, high risk is for up and comers. Sell and diversify and protect your huge nest egg
