<prompt> Human: So my grandfather passed away sooner than he expected last year from a stroke, he was a great guy and more libertarian than most blue collar Pennsylvanians. He worked for the same electric power company his entire life from a lineman to managing over 500 people, and many times he was payed in company stock rather than money, for reasons Im not aware of. Well, his company, when he started working, was a small regional company with less than 100 employees, and the company now has grown incredibly larger, providing electricity to 14 states and some parts of Britain, I think. Well, I was awarded all of my grandfathers company stock in his will, which is a little under 2 of the company. I have been stationed overseas as a combat medic for the past year and just found all of this out from my mom a few days ago, and I figured the stock was worth a few thousand dollars, woohoo. Well I met with my grandfathers lawyer yesterday and discovered that the total value of the stock is somewhere around 5 MILLION DOLLARS. So I am completely astounded, and Im not sure what exactly I should do with this stock, to sell it or hold onto it for the future. Any advice or choice you think I have would be greatly appreciated reddit! Edit:So Ive gotten a lot of helpful replies and messages, so I would like to explain further. I just got off the phone with my uncle who kind of works in the financial sector, hes a logistical operations manager in a big retail company. Apparently my Grandfathers lawyer is an old anti-bank guy himself, and I only inherited .12 of the Company, not 2, which is still around 5 million dollars. The thing is, my grandfather hadnt updated his will in almost nine years, and Im sure he meant to distribute the stock among my siblings and cousins, I am his oldest grandson you see, but his stroke hit all of us by surprise. So I want to find a way to somehow distribute the stock among my sister and my cousins as well as sell it or invest. u1k2tog had good advice about taxes and diversifying, so I was wondering; what companies or services would be best to consult?  <response>: since it has been inherited and passed through the estate you receive a step-up in basis to FMV at date of death. you can sell it with little to no tax consequences. go talk to someone about diversification. congrats on never having to work again if you dont want to.
