How to Spot Zombie Stocks and Mutual Funds
A zombie investment is an investment that stays in your portfolio even though you may no longer have a good reason to own it.
For stocks, investors should examine the company’s sector, earnings, cash flows, debt, and business outlook.
They should also compare the company with similar businesses.
One bad quarter does not always mean a stock is permanently weak.
A mutual fund may have a difficult period because markets or investment styles move in cycles.
Investors should look for steady underperformance against the fund’s benchmark and similar funds over three to five years.
They should also check whether the fund’s strategy or holdings have changed.
A portfolio review every six months can help investors decide whether each investment still supports their goals.
Zombie investments remain in portfolios even after their original investment rationale is no longer valid.
Investors should assess a stock’s sector, earnings, revenue, cash flows, debt, and returns on invested capital.
A weak quarter or year may reflect a temporary cyclical slowdown rather than a lasting business problem.
Mutual funds should be judged against their benchmarks and category peers over three to five years, not just short-term results.
Investors should review and rebalance their portfolios every six months to check whether each holding supports their financial goals.
