What this ETF is trying to do

The Janus Henderson Mortgage-Backed Securities ETF (JMBS) is an exchange-traded fund that invests in mortgage-backed securities. These are types of investments that are bundled together and backed by mortgages.

What the numbers show

As of September 18, 2026, the share price of JMBS was $43.39. To understand how the fund has performed, we look at two different types of returns: price return (which only tracks the share price) and total return (which includes the distributions paid to investors).

• Year-to-Date (YTD): The price return is -5.03%, while the total return is -1.68%.

• One Year: The price return is -4.97%, but the total return is 0.07%.

• Three Year: The price return is -2.19%, while the total return is 14.38%.

An estimated price from roughly one year ago was $45.66. If you had invested $10,000 based on that estimated price, the price-only decline of -4.97% over the last year would mean your investment's share value would be worth approximately $9,503.

Income and distribution explanation

JMBS pays out cash to investors, usually on a monthly basis. Over the last 12 months, it made 12 payouts. The distribution yield is approximately 5.41%.

It is important for beginners to know that a high distribution yield alone can be misleading. A fund can pay out a high yield even if the share price is falling. In this case, the total return figures are higher than the price return figures because the distributions added value back to the investor.

NAV erosion explanation

"NAV erosion" happens when the net asset value of a fund steadily declines, which can eat away at an investor's original principal. StockValueFinder uses an erosion-risk score to measure this.

JMBS has an erosion score of 94, which is labeled as "Stable / sideways" with "good" severity. Additionally, the severe erosion-risk flag is false, meaning the fund's price trend did not trigger a severe warning.

Pros

• Positive Long-Term Total Return: While the share price has declined over three years, the total return (including distributions) is 14.38%.

• Consistent Income: The fund has a history of monthly payouts and an income rating grade of "A."

• Stability: The erosion-risk score suggests the fund is currently stable.

Cons

• Falling Share Price: The price return has been negative over the short and long term (YTD, one year, and three years).

• Recent Performance: The total return for the year-to-date period is negative (-1.68%).

Beginner takeaway

JMBS provides regular monthly income, but its share price has trended downward. This shows why it is important to look at total return rather than just the share price or the distribution yield. While the share price has dropped, the distributions have helped offset those losses over the long term.
