This ETF selects U.S. large-cap stocks using a fundamental weighting method. Instead of market capitalization, it weights holdings by measures of corporate size such as sales, cash flow, dividends and share buybacks, aiming for a structure that is less swayed by market prices.

It suits long-term investors who want value-leaning large-cap exposure at a low cost, distinct from traditional market-cap-weighted core ETFs.

It is a passive (index-tracking) ETF managed by Schwab.

Holdings are weighted by fundamental metrics such as sales, cash flow, dividends and share buybacks rather than market capitalization. This approach is intended to reduce a limitation of market-cap weighting, in which expensive stocks automatically receive larger weights, and as a result the portfolio shows a value tilt.

• Weighting based on fundamental metrics, not market cap
• Value-leaning large-cap exposure at a low expense level

Assets under management (AUM) stand at $28.3B, and the expense ratio is 0.25% per year.

Its fees are lower than those of competing ETFs that use the same fundamental approach, and its stock weightings differ from those of typical market-cap-weighted core ETFs.

During periods when value stocks are strong, the fund tends to outperform market-cap-weighted indexes, and during growth-led periods it tends to lag. Because its technology weighting is lower than that of market-cap-weighted indexes, performance gaps emerge depending on the market regime.

Thanks to its low fees and fundamental weighting, capital seeking a core alternative has flowed in steadily. In volatile markets, money sometimes shifts toward value-oriented assets, and overall the fund belongs to the large-cap category.

Its strengths are low fees and the distinctiveness of fundamental weighting, while its weakness is relative underperformance when growth stocks are leading.

Among the comparison ETFs shown in the table, a direct substitute using the same fundamental weighting method and the small-cap version of the same Schwab Fundamental series are presented together. Meanwhile, if you want a traditional market-cap-weighted core, you can consider a Schwab large-cap ETF such as SCHX, and for a stronger focus on the value style, SCHV. The performance gap between fundamental weighting and market-cap weighting is the key selection criterion.

These are the points to check before investing in FNDX. It is important to confirm whether the distinctive fundamental weighting fits your portfolio preferences, and to review fees and style exposure.

Relative weakness in growth-led phases and the low technology weighting are the main drivers of short-term performance gaps. Fundamental weighting does not always come out ahead, so the prevailing market style regime should be considered as well.

It suits long-term investors who want value-leaning large-cap exposure, different from market-cap weighting, at a low cost. If a traditional core comes first, compare it with SCHX, and if you want a value focus, compare it with SCHV before choosing.
