United States treasury bonds have been in bull market since the early 1980s, confounding many bond trading experts that have long expected treasury bonds to reverse course and decline in value.  With United States treasury bonds at multi-decade highs in price, it may be time to consider buying a short treasury Exchange Traded Fund (ETF), short treasury ETF, to profit from the eventual rise in United States interest rates that will cause United States treasury bonds to decrease in value and the holdings of a short treasury ETF to increase in value.
