Fund profile
This fund files no prospectus profile. Unit investment trusts and closed-end funds register on forms that carry no objective or fee tagging, and some fund families file without it — a gap in what was filed, not a fund without an objective or without fees.

Portfolio growth profile
How much of the fund’s stock holdings are in fast-growing companies · as of 2026 Q2
Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-04-30
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 | 69.2% |
| Zero-coupon or unclassified | 21.1% |
| Floating rate | 9.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.2% |
| 1-3y | 25.4% |
| 3-5y | 41.9% |
| 5-10y | 27.9% |
| 10y+ | 3.6% |
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
More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.
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.
| Credit spreads | 61% |
| Interest rates | 39% |
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.
| High yield | +0.85 yr |
| Investment grade | +0.21 yr |
Share of duration at each point, shortest first. This filer signs its rate and credit disclosures differently; the direction shown follows its interest-rate filing, and a negative reading is the least-supported figure here.
| 3 mo | 0.01 yr | 1% |
| 1 yr | 0.17 yr | 24% |
| 5 yr | 0.42 yr | 62% |
| 10 yr | 0.07 yr | 11% |
| 30 yr | 0.01 yr | 2% |
| 3 mo | 0.02 yr | 2% |
| 1 yr | 0.32 yr | 30% |
| 5 yr | 0.62 yr | 58% |
| 10 yr | 0.09 yr | 9% |
| 30 yr | 0.02 yr | 2% |
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.
