The Bottom Line
Two words of caution when investing in high-yielding vehicles: First, the price of the investment could move dramatically to the downside, and therefore a 40% drop in the price of the stock could wipe out a 19% dividend yield. Second, the dividend payouts are not guaranteed, and could change at any time.
