The Art of Prudent Investing: Insights on Bonds and Preferred Stocks

Investing in fixed-value securities, such as corporate bonds, centers on creating a dependable income stream. Prioritize high-grade securities, focusing on a company's consistent ability to meet its obligations, especially under adverse conditions. Avoid the temptation of higher coupon rates that compensate for deficient safety; the primary goal is to safeguard the principal. Employ strict quantitative tests to exclude questionable securities, working upwards regarding yields. When assessing interest coverage, include all obligations equivalent to bond interest, such as rentals and guarantees. Preferred stocks, while similar to bonds, lack a specific maturity date and enforceable claims, making them less attractive for fixed-value investments. If considering them, raise the minimum standards significantly. The interest coverage ratio must encompass payments on both bonds and preferred stocks. Senior securities of inadequate safety should be approached like common stocks, requiring a substantial discount from par value to compensate for the increased risk. Senior securities with speculative privileges, such as convertibles, offer a blend of safety and potential appreciation. Evaluate these based on the extent of profit-sharing, closeness to realizable profit, and duration of the privilege. In market turmoil, opportunities may arise to switch between securities based on mathematical advantages, such as when a convertible senior security is priced near parity or at a discount compared to the common stock. Rigorous analysis and a focus on quantitative standards are essential for intelligent investing in bonds and preferred stocks.
