Loomis Sayles Investment Grade Bond Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Loomis Sayles Investment Grade Bond Fund held 1,086 positions with $17.02B in net assets. Its ten largest holdings made up 18.6% of the fund. The LIGRX share class costs 0.73% a year. Over the 12 months to May 2026, LIGRX returned 5.3%, with dividends reinvested. In 2026 Q2 it added 126 new positions and exited 113.
The Fund seeks high total investment return through a combination of current income and capital appreciation.
The fund invests at least 80% of assets in investment-grade fixed-income securities selected by the adviser based on improving credit profiles, issuer-specific rather than market-driven price sensitivity, and attractive yield spreads relative to risk; it may hold up to 15% in below-investment-grade bonds and up to 30% in dollar-denominated foreign securities. The fund's returns depend on the adviser's security selection and credit analysis rather than tracking an index. The adviser may also use derivatives, bank loans, mortgage-backed securities, and structured notes to implement its strategy.

How it has done
LIGRX share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.36%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
The 5 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.73% | +5.30% | +15.08% | +5.12% | -4.30% | |
| 1.48% | +4.47% | +12.52% | +1.20% | -4.43% | |
| 0.48% | +5.55% | +16.06% | +6.47% | -4.23% | |
| 0.98% | +4.92% | +14.08% | +3.68% | -4.37% | |
| 0.43% | +5.60% | +16.05% | +6.66% | -4.23% |
These classes hold the same portfolio, so the 5.45pp spread over 5 years is the cost difference between them — roughly 1.09pp a year — not a difference in what they own.

Turnover is how much of the portfolio was replaced in a year.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-06-30
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 81.4% |
| Floating rate | 17.4% |
| Zero-coupon or unclassified | 1.2% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.4% |
| 1-3y | 5.9% |
| 3-5y | 14.3% |
| 5-10y | 38.5% |
| 10y+ | 40.8% |
These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
Most of this fund’s sensitivity is to interest rates, with credit spreads carrying nearly as much.
Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.
| Interest rates | 59% |
| Credit spreads | 41% |
Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.
Share of the fund's spread duration carried by each credit tier.
| Investment grade | +3.53 yr |
| High yield | +0.68 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 1 yr | 0.61 yr | 10% |
| 5 yr | 1.70 yr | 28% |
| 10 yr | 2.39 yr | 40% |
| 30 yr | 1.30 yr | 22% |
3 mo is NEGATIVE (-0.01 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.02 yr | 0% |
| 1 yr | 0.44 yr | 10% |
| 5 yr | 1.79 yr | 43% |
| 10 yr | 1.66 yr | 39% |
| 30 yr | 0.31 yr | 7% |
The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
