I inherited $600K in Apple stock. It now makes up 50% of my portfolio. Is that too risky?

Core Viewpoint - The dilemma revolves around the decision to hold or sell a significant portion of Apple shares inherited from a mother, weighing emotional ties against financial strategy [2][4][5]. Investment Strategy - The overall investment portfolio is valued at approximately $600,000, with Apple shares constituting about 50% of this portfolio [2]. - The broader investment strategy focuses on dividend-paying ETFs across various sectors, with a retirement horizon of 10 years [2]. Performance and Risks - Apple stock has shown strong performance overall, despite some dips, and has recently climbed in value [3]. - Concerns exist regarding potential downturns in the tech sector or company-specific issues that could significantly impact the portfolio [4]. - The annual dividend from Apple shares amounts to about $1,000, which is relatively low compared to the overall investment [3]. Emotional Considerations - The emotional connection to the Apple shares is significant, as they represent financial security for the mother, who purchased them at around $8 per share [4]. - There is a sense of disloyalty associated with the idea of selling even a portion of the shares inherited from the mother [4]. Investment Philosophy - Holding 50% of the portfolio in a single stock like Apple requires strong belief in the company's future performance [8]. - Concentrating a large portion of investments in one company is generally considered risky, as it can lead to substantial losses or significant gains [9].
