Question: What is a "blue chip" and what does it have to do with my investments?
Answer: A "blue chip" is the nickname for a stock that is thought to be safe, in excellent financial condition, and firmly entrenched as a leader in its field. Blue chip stocks generally pay very large and growing dividends, making them favorably regarded by investors. A few examples of blue chips are Wal-Mart, Coca-Cola, Procter & Gamble, Exxon Mobil, PepsiCo, McCormick & Company, Unilever, and Johnson & Johnson.
Blue chip stocks are sometimes referred to as bellwether issues, though that is a phrase that has died off in the past ten or fifteen years as the older generation of investors has gone to the grave, to be found only in the pages of old news stories and academic books.
