In some cases it might be smart to pull your money out of certain stocks when they reach a predetermined price (you can use a limit order to set those guardrails); when you want to buy into new opportunities; or add diversification to your portfolio.
When should you cash out stocks?
Investors might sell their stocks is to adjust their portfolio or free up money. Investors might also sell a stock when it hits a price target, or the company's fundamentals have deteriorated. Still, investors might sell a stock for tax purposes or because they need the money in retirement for income.
