Lots of flavors- Treasuries, corporates, munis. Invesco calls theirs bullets or something. They are etfs that essentially expire. You can buy a 1-3yr treasury etf, but it will still move around with the short term rate because they are constantly reinvesting the funds in new bonds. The etfs that expire don’t do that. They pay you cash back and you reinvest. Look at fact sheet and SEC yield or Yield to maturity for rate. As per industry standard, all the rates are annualized.
