Say, a U.S.-based software company is trading at a price of $100 and has a market capitalization of $5 billion. A news item comes in that the EU regulator has imposed a fine of $2 billion on the company which essentially means that 40 percent of the company’s value may be wiped out.

Safety,” supposedly, is what bond buyers want, but there is nothing inherently safe in yields quoted below the rate of inflation. It's closer to the mark to say that people buy bonds because they believe that the currencies in which those securities are denominated will not go the way of all other paper currencies since the invention of the printing press. Inflation may eventually consume them, the line of reasoning goes, but not just yet.

For instance, a stock exchange may categorize stocks in various segments depending on their risk profiles and allow limited or no trading by common investors in high-risk stocks.
