Equities posted solid results driven by better-than-expected earnings across a broad swath of the market. Market influences included an end to the U.S. Federal Reserve (Fed) interest rate hikes and expectations for lower rates going forward. Further, continued progress on inflation moving towards the Fed target and positive resiliency in the U.S. economy resulted in strong GDP growth.

A rebound in inflation early in 2024 ultimately subsided while labor markets showed clear signs of softening, allowing the Fed to signal its intention to begin the process of reducing interest rates later in the year.

| Factors Affecting Performance [Text Block] | Management’s Discussion of Fund Performance SUMMARY OF RESULTS High Yield Fund (Class 1/JIHDX) returned 11.65% for the year ended August 31, 2024. U.S. Treasury bond yields fell as economic data continued to soften. Most notably, U.S.Treasury bonds and and risk assets experienced extreme volatility during August. Softer readings for both jobs and inflation bolstered the market’s expectations for rate cuts by the Federal Open Market Committee. Global growth and inflation rates continued to decline. Ongoing deflationary pressures in China, tightening financial conditions in the U.S. and Europe, and subdued demand for manufacturing and services in several countries eased price pressures worldwide. Within high yield, the potential for total returns at high single-digit yields remained relatively attractive compared to other higher-volatility alternatives.

Equity markets generated significant gains. Major indexes began to climb toward the end of 2023 following some favorable economic data releases, which gave investors hope that policymakers may be able to achieve their goal of a "soft landing" without sparking a recession. Aside from brief sell-offs in April and August, equities continued on their upward trajectory in 2024, bolstered by certain favorable earnings reports, strong investor interest in companies expected to benefit from artificial intelligence developments, and ongoing tailwinds of an economic rebound.

| Factors Affecting Performance [Text Block] | Management’s Discussion of Fund Performance SUMMARY OF RESULTS Capital Appreciation Value Fund (Class NAV/JCAVX) returned 16.22% for the year ended August 31, 2024. Stocks rallied as falling inflation raised hopes that the U.S. Federal Reserve would start cutting interest rates. Positive global growth, steady corporate earnings, and excitement surrounding the adoption of AI added to the upbeat tone. In this environment, U.S. equities, the growth style, and the information technology sector outpaced the market as a whole. Bonds also produced gains, with income accounting for the majority of the category’s total return. Credit-oriented categories generally outperformed those with higher interest-rate sensitivity.
