I have a wealthy family member that is trying to obtain a steady stream of income using the money that have built up in the stock market over the past 10 years. We were looking at a bond ETF like VCSH or AGG. Also I found some junk bond ETFs that pay a higher yield. My question is Since the bond etf does not mature, you have a risk of not being repaid the total amount of capital. The amount you get “repaid” just depends on the price of the bond etf when you sell it? Is that accurate. Can these bond ETFs go to zero? Also, if a company defaults on the bond, how much of an affect will that have in the etf or yield, considering some of these ETFs hold thousands of corporate bonds. What other risks are we looking at by using these instruments? Are they considered generally safe for preserving capital and creating income streams? Thanks.
