What Chimpanzees Can Teach Us About Convertible Bonds

In a renewed commitment to finally learn Spanish, one of my colleagues spent quite a bit of time this week awkwardly saying, “Qué es eso?” into the headset Rosetta Stone provides with its language learning programs. Translation: “What’s that?”

Here in the US, the 10,000 or so people reaching retirement age each day often find themselves asking the same question—though maybe not out loud—when advisors use terms of art or casually mention sophisticated investment options. What’s that? Most of these folks didn’t earn their living in the financial services sector, so they don’t speak the language—nor should they feel embarrassed about it.

That said, no one—particularly risk-adverse retirees—should ever invest in something they don’t understand. So let me add one more type of investment to your “I know about that” toolbox: convertible bonds. Despite their obscurity, they’re not the least bit complicated.

Put simply, convertible bonds:

  • have, as a rule of thumb, two-thirds of the upside of common stock and one-third of the downside; and
  • can be an excellent way to diversify your portfolio.

Convertible bonds are bonds an investor (let’s say it’s you) can convert into common stock of the issuing company under certain circumstances. Imagine, for example, that Rosetta Stone wants to finance a new project—maybe it’s doing R&D on how to teach humans to speak the language of chimpanzees (hey, this is purely hypothetical). So Rosetta Stone (RST), which has a current stock price of about $8.80, issues a convertible bond and sets the conversion rate so that it’s not profitable to convert your bonds unless the stock price rises, say to $11.

Then more people start to feel a burning need to learn Spanish—or Mandarin, or Farsi—and RST’s price passes $11. At that point, you can convert your bonds into shares of RST worth more than the stream of payments from the bond alone. You own bonds with upside potential.
