I have always invested in Index funds in a 401k and IRA and understand the implications with those. Last year (1 year and 1 month ago) I purchased $15,000 worth of Marvell stock in a brokerage account. I believe that I would owe long term capital gains and state income tax on this only? It’s now worth over $30,000. I don’t need the cash but feel like maybe I should lock in some gains selling half of it or so and let the other half ride? Thanks in advance.
