==History==
Historically, most high-yield bonds were originally investment-grade bonds which were downgraded to junk status. These emitters are known as "fallen angels".Raymond Kerzérho, Spotlight on high-yield bond ETFs, June 11, 2019, viewed January 11, 2020
High-yield bonds were infamously promoted as an asset class by Michael MilkenWikipedia, Michael Milken, viewed Feb. 18, 2009. of Drexel Burnam LambertWikipedia, Drexel Burnham Lambert, viewed Feb. 18, 2009. in the 1980s as a means to finance leveraged buyouts. Milken was later jailed on charges of insider trading; and Drexel later failed, after posting its first losses in its history.
Since the mid-1980s, rather than being fallen angels, the majority of junk bonds are immediately rated as suchBernstein W (2001) Credit Risk: How Much? When?

==Risks==
===Credit risk===
High-yield bonds carry a lower rating because the issuing entity is considered to have a greater than average default risk – that is, there is a risk that it would not be able to pay its debts and be forced into bankruptcy. Should bankruptcy occur, bondholders would probably receive significantly less than the face amount of the bonds. For the period 1978-1997, the default rate on US high-yield bonds ranged from 0.2% to 10.3%.Altman EI (1998) The Anatomy of the High Yield Bond Market: After Two Decades of Activity-Implications for Europe. New York University, Center for Law and Business, Working Paper #CLB-98-021, viewed December 29, 2018. Among defaulting issues, the average recovery was about 40% of face value during this period. Since 1997, the default rates have ranged from less than 2% to over 10%.
===Call risk===
Issuers typically call their bonds when the interest rate goes down. High yield bonds come with additional call risk. If the issuers' credit ratings improve, they can call the existing bonds and borrow money at a lower interest rate. This type of call risk is not applicable to bonds with high ratings.
In 2018, 98% of bonds in the Barclays U.S. Corporate High Yield Bond Index had a call feature.
===Skewness===
Junk bonds have negatively skewed returns, meaning that there is a long tail of low returns in the distribution. In other words, there are more large losses than a normal distribution would imply. This is true of many asset classes, but the negative skew of junk bonds is worse than that of equities or investment-grade bonds.

==Canada versus US==
==Canada versus US==
Canadian bonds are rated by three bond rating agencies: DBRS, Moody's and Standard and Poor's, which bought the Canadian Bond Rating Service in 2000.
The Canadian market for high-yield bonds is comparatively small: as of December 2018, the FTSE TMX Canada High Yield Bond Index contained 43 issues with a total market value of 11 billion Canadian dollars.
In contrast, the US is the largest junk bond market in the world, worth about 1200 billion US dollars as of July 2018.Bloomberg, The Corporate Bond Market Is Getting Junkier, July 2018, viewed December 30, 2018 
==Place in portfolios==
High-yield bonds can add additional income but carry higher risks. Because of these risks, authors disagree on their use in a portfolio. In a Bogleheads topicBogleheads.org, Swedroe versus Ferri on Recommended Asset Classes, viewed Feb. 23, 2009., the different approaches of investment authors Richard Ferri and Larry Swedroe is discussed: Ferri thinks that high-yield bonds have a place in portfolio design but Swedroe disagrees. The poor performance of some Canadian high-yield bond funds in 2008 has been noted by Luukko.Rudy Luukko, Tread carefully with junk bond funds, Feb. 21, 2009.
===Arguments for===
* The higher yield relative to investment-grade bonds: an average of 5% extra yield in the US during 1987-2012 (do not confuse this 5% extra yield with a 5% extra total return: defaults have to be accounted for)
* On individual bonds, a possibility of capital gains if the issue is upgraded to a better rating
* Diversification benefit due to low correlation with other types of fixed incomeCanadian Couch Potato, High-Yield Bonds and Your Portfolio: Part 2, October 6, 2010, viewed December 24, 2018
===Argument against===
* Bonds are supposed to be safe and provide ballast, but high-yield bonds are volatileCanadian Couch Potato, High-Yield Bonds and Your Portfolio: Part 1, October 4, 2010, viewed December 24, 2018
* High-yield bonds can be correlated with equities, and go down in price along with equities during bear markets
* They can be difficult to trade in a bear market
* According a Vanguard study, adding high-yield bonds to a portfolio of investment-grade bonds and equities did "not significantly boost a portfolio's risk-adjusted returns" for the period 1986-2013, i.e. junk bonds are not actually good portfolio diversifiers
* Very few of the active mutual funds, and none of the ETFs, managed to match or beat the U.S. Corporate High Yield Bond Index (over 5 years) due to factors such as liquidity costs and other expenses 
==Implementation==
Due to the high risk of this asset class, investors could very easily choose not to include it at all in their portfolios. For those that want to go ahead:
* The amount of high-yield debt in the portfolio should be limited. FerriFerri, Richard A., All About Asset Allocation, McGraw-Hill, 2006. Page 149. recommends that 10-20% of the total bond allocation be in high-yield debt. Other investors count junk bonds in the equity category: they keep their investment grade bonds intact, but allocate some of their risky assets (typically, equities) to junk bonds.
* The high default risk makes diversification essential, and high trading costs make individual bond purchases unwise, so investors should almost always purchase high-yield bonds as part of a low cost mutual fund or exchange-traded fund (unless they are willing and able to analyze corporate debt structure and diversify across many issues)
