What this ETF is trying to do

The Thornburg Core Plus Bond ETF (TPLS) is an exchange-traded fund that focuses on bonds. Generally, bond ETFs are used by investors who want to earn regular income from interest payments.

What the numbers show

As of October 5, 2026, the share price of TPLS is $23.91.

When looking at performance, it is important to distinguish between price return (how the share price changed) and total return (which includes the share price change plus distributions).

• Year-to-Date (YTD): The price return is -6.09%, while the total return is -2.84%.

• One-Year: The price return is -6.66%, while the total return is -2.06%.

To put this in perspective, the estimated price from roughly one year ago was $25.62. If an investor had put $10,000 into the ETF based on that estimated price, the value of those shares alone would have declined by approximately 6.66% over the year.

Income and distribution explanation

TPLS pays out distributions usually every month. Over the last 12 months, it has made 12 payouts totaling $1.21 per share. This results in a distribution yield of approximately 5.08%.

It is important for beginners to remember that a high distribution yield alone can be misleading. A fund can pay out a high percentage in cash even while its share price is falling.

NAV erosion explanation

"NAV erosion" happens when the net asset value (the actual value of the fund's holdings) declines over time. While a falling share price does not always prove the NAV is eroding, StockValueFinder uses an erosion-risk score to monitor this.

TPLS has an erosion score of 75, which is labeled as "mild price erosion." This is a measurement of erosion risk, not a guarantee that the fund's value has collapsed. The severe erosion-risk flag for this ETF is currently false.

Pros

• Regular Income: The fund provides frequent payouts, usually on a monthly basis.

• Lower Total Loss: The total return is less negative than the price return, meaning distributions helped offset some of the share-price decline.

Cons

• Price Decline: The share price has decreased both year-to-date and over the last year.

• Erosion Risk: The fund has a "mild" erosion-risk label.

Beginner takeaway

TPLS provides monthly income, but its share price has been trending downward. Income investors care about "principal stability," which means they want the original amount they invested to stay steady. In this case, the distributions provided some value, but they did not fully stop the overall decline in the investment's total return.
