Concerned About Interest Rates Rising? Consider Convertibles

Over the past few months, several major companies involved in the automotive, telecommunications, energy and other industries have issued convertible securities to help fund their business activities. Some investors may not be familiar with convertibles, but given their historical outperformance during times of rising interest rates, I believe now is the time for investors to peer under the hood and learn how convertibles work.

What are convertibles?

A convertible bond is a corporate bond that has the added feature of being converted into a fixed number of shares of common stock. They make up a small, but important, part of the capital markets.

The asset class weighs in with a market value of about $207 billion in the US, which is considerably smaller than the $1.35 trillion domestic high yield market.1 Yet convertible securities provide an important source of financing for companies.

What makes convertibles especially attractive today, in my view, is their historical performance during periods of rising interest rates. In fact, the table below shows that:

  • In each of the last 10 periods of rising interest rates in the US going back to 1989-1990, the performance of convertibles has exceeded that of US government bonds.
  • Converts also outpaced the returns of the high yield market in a majority of those timeframes.
  • They even outperformed the S&P 500 Index during almost half of those periods.

Thus, investors seeking an alternative to traditional fixed income in a rising rate environment may want to consider converts given their history of outperformance in those periods.

What drives convertible performance?

There are several reasons behind these results.
