FLTB vs SPSB

FLTBDFidelity Limited Term Bond ETF

SPSBAState Street SPDR Portfolio Short Term Corporate Bond ETF

In short

FLTB Fidelity's short-bond ETF skips the index rulebook: a manager team picks 1-5 year corporate credit, using Fidelity's own blended yardstick as a guide rather than a cage. One of the original active bond ETFs, running since 2014.

SPSB The short end of the corporate bond market, bought wholesale: roughly 1,600 investment-grade corporate bonds maturing in one to three years, for four basis points. Built as a cash-adjacent building block, not a yield swing.

Stated mandate

FLTB The fund is a shorter-duration, investment-grade bond strategy focused primarily on U.S. corporate credit.

SPSB The fund seeks to track the price and yield performance of the Bloomberg U.S. 1-3 Year Corporate Bond Index before fees and expenses.

Why people hold it

• FLTB Actively run since its 2014 launch, with Fidelity's blended 1-5 year credit, government and high-yield composite used as a guide for allocation, not a set of tracking handcuffs.fidelity.com
• The mandate reaches past plain investment grade: the guiding blend carries a slice of short-dated BB-B high yield alongside 1-5 year corporate and government debt.fidelity.com
• Short maturities mean smaller price swings when rates move than longer-dated bond funds carry, and income is paid out monthly.
• Spreads its credit risk across roughly 500 positions, so no single issuer carries the portfolio.

• SPSB Costs 0.04% a year against a 0.19% median for investment-grade corporate bond funds. At the short end, where yields are thin, that gap is a real slice of what you keep.
• Nothing in the index matures past three years, so rate moves push the price around less than they do at intermediate corporate funds like SPIB or VCIT.ssga.com
• Roughly 1,600 bonds, market-cap weighted, reconstituted at each month end, with a $300 million minimum issue size. Income arrives monthly.ssga.com
• Trading since 2009 and now a multi-billion-dollar fund that changes hands actively, one of the sturdier implementations in its peer group.

Worth knowing

• FLTB It charges 0.25% a year, above the cohort median, while index rivals like IGSB, SPIB and VCIT run a few basis points. Active management is what the extra buys.
• Moderately traded and mid-sized rather than a volume giant, so bid-ask spreads can run wider than at the largest corporate bond ETFs.
• The latitude to hold high yield and non-index sectors adds credit risk you would not get from a pure investment-grade tracker.fidelity.comfidelity.com 2

• SPSB Pure corporate credit, no Treasury ballast. Investment-grade paper still reprices when spreads widen, short maturities or not.ssga.com
• Bonds roll off fast and get replaced at whatever the market pays, so the income stream follows prevailing rates in both directions.ssga.com
• The manager samples the index rather than buying every bond in it, so the portfolio can drift modestly from the benchmark.sec.gov
