JPMorgan BetaBuilders U.S. Equity ETF

JPMorgan BetaBuilders U.S. Equity ETF (BBUS) is an index fund that tracks the Morningstar US Target Market Exposure Index, which covers about 85% of the US stock market by value, mostly large and mid-size companies. Its main draw is cost: the expense ratio is 0.02%, per the prospectus filed February 25, 2026, against a 0.09% average for similar funds. Like any broad US stock fund, it rises and falls with the market.

• Over the year to Oct 27, 2026, BBUS returned +13.0%, 5th of 9 among similar funds.
• Its 5-year annualized return was +12.2%.
• In the 2020 COVID crash it fell 33.8% and regained its old high 4.5 months after the low.
• Its worst full calendar year was 2022 (-19.5%); its best was 2023 (+27.2%).
• The deepest fall in its price history was 35.3% (Jan 16, 2020 to Mar 23, 2020), recovered by Aug 24, 2020.

As of Jul 31, 2026, the fund held 469 securities; the ten largest made up 37.31% of assets.

By sector

• Over the three months to Jul 31, 2026, investors added a net $742.9M (creations minus redemptions, per the N-PORT report).
• Monthly total returns reported for that quarter: +5.27%, -0.94%, -0.13%.

BBUS tries to match the Morningstar US Target Market Exposure Index before fees. The index holds US-traded stocks that make up about 85% of the market by value, mainly large and mid-size companies. As of January 30, 2026, it had 491 securities, ranging from $2.8 billion to $4.5 trillion in market value. Stocks are weighted by free-float market capitalization. That means bigger companies get bigger weights, counting only shares available for public trading.

The fund aims to replicate the index, which means owning nearly every stock in roughly the same proportions. When that isn't practical, it may use representative sampling, holding a subset chosen to behave like the index. Even then, at least 80% of assets must be in index stocks. The fund rebalances quarterly along with the index, and portfolio turnover was 3%. It may put up to 10% of assets in exchange-traded futures to help track the index. As of July 31, 2026, it held one tiny S&P 500 futures position.

Because of the market-cap weighting, a few giants dominate. As of July 31, 2026, the fund held 469 stocks, but the top 10 made up 37% of assets, led by NVIDIA (7.3%), Apple (7.0%) and Microsoft (5.4%). Technology made up about a third of the portfolio. Because the fund is passive, it won't sell a struggling company unless the index drops it.

• BBUS charges 0.02% a year, versus an average of 0.09% for the similar funds below (2nd of 9, cheapest first).
• Using the prospectus's standard example, $10,000 invested would cost about $2 in the first year and $26 over 10 years (assuming a 5% annual return).

It offers broad, very low-cost exposure to large and mid-size US stocks, which could anchor the stock side of a long-term portfolio.

BBUS could serve as the US stock core of a long-term portfolio. In the SEC's standard example, $10,000 invested would cost about $2 in the first year and $26 over 10 years. It holds only stocks, so it falls hard in bear markets. It launched in March 2019, so it has no 2008 record. In the 2020 COVID crash it fell 33.8% in about five weeks, then recovered by August 2020. In the 2022 bear market it dropped 25.4% and needed about 14 months from the low to regain its peak. Its worst calendar year was 2022, at -19.43%. Selling shares during such a slump locks in losses, which is why many retirees hold cash or bonds alongside a fund like this. The yield was 0.99% as of October 27, 2026, paid quarterly, which is too small to be a main income source. Past results don't predict future returns, and a plan should look at the whole portfolio, not one fund.
