Our read on SDSI

ETF.net Research

BActive short-duration credit in an ETF wrapper. Managers roam investment-grade and high-yield corporates, government paper and securitized debt, US and overseas, chasing income while keeping rate sensitivity short.

Stated mandate

The fund seeks current income and, secondarily, long-term capital appreciation. It uses active bond selection and tactical sector management across U.S. and non-U.S. markets.

Why people hold it

  1. 01Short by design. It measures itself against the Bloomberg U.S. 1-3 Year Government/Credit index, so it carries far less rate sensitivity than the intermediate aggregate funds that define this category.americancentury.com
  2. 02Go-anywhere toolkit: investment-grade and high-yield corporates, Treasuries and agency paper, mortgage- and asset-backed bonds, US and non-US, spread across roughly 400 positions.americancentury.com
  3. 030.32% a year undercuts the median fund in its bond cohort, unusual for active management, and holdings are disclosed daily rather than quarterly.americancentury.com
  4. 04Income is the stated first objective, with capital appreciation second, and the fund's policy is to pay distributions monthly.

Worth knowing

  1. 01Cheap for active, pricey next to index. BND, SCHZ and SPAB each charge 0.03%, so the managers' sector calls carry the whole burden of justifying the gap.
  2. 02The high-yield sleeve is where the extra income comes from, and it is also where credit stress shows up first. This is not a Treasury-only short bond fund.americancentury.com
  3. 03It trades lightly compared with the index heavyweights in its cohort, which tends to mean wider spreads. Limit orders matter more here than with a mega-fund.
