HYG vs SPHY

HYGBiShares iBoxx $ High Yield Corporate Bond ETF

SPHYAState Street SPDR Portfolio High Yield Bond ETF

In short

HYG A 2007-vintage junk bond ETF built around liquidity: a multi-billion-dollar fund, heavily traded, tracking an index screened for the market's more tradable bonds. The trade-off is a fee well above the category's cheapest.

SPHY State Street's junk-bond workhorse: roughly 1,900 US high yield bonds in one wrapper for 0.05% a year, a fraction of what the typical high yield ETF charges, with income paid monthly.

Stated mandate

HYG The fund seeks to track an index of U.S. dollar-denominated high-yield corporate bonds.

SPHY The fund seeks to track, before fees and expenses, the price and yield performance of the ICE BofA US High Yield Index.

Why people hold it

• HYG Running since 2007 and now a multi-billion-dollar fund that trades very actively, so thin days and wide spreads are rarely the sticking point.
• Follows the Markit iBoxx USD Liquid High Yield Index, which leans on larger, more tradable bonds instead of every scrap of paper in the junk market.ishares.com
• Income arrives monthly, and the mandate stays plain: a standard 1940 Act fund holding US dollar-denominated high-yield corporate bonds, index-tracked.
• Sticks closely to what its documents promise, and rates among the stronger implementations in a crowded high-yield field.

• SPHY 0.05% a year against a peer-group median about eight times higher. In high yield, the fee comes straight out of coupon income, so the gap does real work.
• Holds about 1,900 bonds tracking the ICE BofA US High Yield Index, broad enough that no single issuer's trouble dominates the portfolio.ssga.com
• Live since 2012, a multi-billion-dollar fund that trades actively and has stuck tightly to its stated index rather than drifting from the mandate.
• Distributions arrive monthly, in step with how the underlying coupons come in.

Worth knowing

• HYG The 0.49% fee sits well above cheaper trackers like SCYB (0.03%) and SPHY (0.05%). You are paying for the trading ecosystem, not for cheaper exposure.
• High yield is below-investment-grade credit. When corporate stress rises, these bonds can move more like stocks than like Treasuries.
• The liquidity screen leaves out smaller issues, so coverage is narrower than broad-market rivals such as USHY.

• SPHY This is below-investment-grade credit. Defaults and spread moves drive the price far more than Treasury yields do, and sell-offs in this asset class can be sharp.
• Fees here are already near the floor: SCYB lists 0.03% and HYLB matches at 0.05%, so the cost edge over the strongest peers is narrow.
• Scope is US high yield corporates, full stop. No investment-grade ballast, no emerging market debt, nothing to soften a credit drawdown from inside the fund.ssga.com
