Share-split context: A forward split was recorded on Dec 7, 2020 with coefficient 2. A forward split turns each old share into multiple new shares and lowers the quoted price per share proportionally. Proportional ownership is unchanged at the split moment, so the split itself creates neither a gain nor a loss. The price-return figures in this report are already split-adjusted.

What this ETF is trying to do

The ISHARES U.S. UTILITIES ETF (ticker: IDU) is designed to provide exposure to the utilities sector in the United States. This type of fund typically invests in companies that provide essential services like electricity, gas, and water. According to the top holdings data, the fund includes companies such as NextEra Energy Inc, Southern Co, and Duke Energy Corp.

What the numbers show

The current price of IDU is $105.03. When looking at how the fund has performed, it is important to distinguish between price return and total return.

• Price Return: This measures only the change in the share price. The year-to-date (YTD) price return is approximately -3.07%, and the one-year price return is approximately -7.84%. However, over a three-year period, the price return was approximately 46.53%.

• Total Return: This includes both price changes and the value of distributions. The YTD total return is approximately -1.41%, and the one-year total return is approximately -5.67%. Over three years, the total return was much higher at approximately 57.37%.

Because this ETF has a history of forward splits, we use split-adjusted returns to understand performance. In a forward split, each old share becomes multiple new shares, and the price per share falls proportionally. This change does not create a gain or a loss for the investor.

Income and distribution explanation

IDU provides cash distributions to investors. The trailing distributions are approximately $2.58 per share, resulting in a distribution yield of approximately 2.46%. The fund usually pays these out on a quarterly basis, with four payments recorded over the last 12 months.

It is important to remember that a distribution yield is not the same as total return. While distributions provide cash income, they do not guarantee that your original investment will stay the same value.

NAV erosion explanation

"NAV erosion" refers to a decline in the Net Asset Value (the actual value of the fund's underlying assets). The supplied data is sufficient to evaluate price erosion, but it does not include enough historical NAV-per-share data to confirm or rule out NAV erosion.

Regarding price erosion, the fund has an erosion-risk score of 75, which is labeled as "Mild price erosion." This is a measurement of price trends and is not a "severe erosion-risk flag," which remains false for this ETF.

Pros

• Strong Long-Term Returns: The three-year total return of approximately 57.37% shows significant growth over that period.

• Regular Income: The fund has a history of quarterly distributions and an income rating grade of "B."

Cons

• Recent Price Declines: Both the year-to-date and one-year price returns have been negative.

• Mild Price Erosion: The fund shows a mild risk of price erosion based on its current score.

Beginner takeaway

IDU focuses on U.S. utility companies. While the fund has seen some share-price declines over the last year, it has shown strong total returns over a three-year period. Investors interested in income should note the 2.46% distribution yield, but they should also watch the mild price erosion score and understand that recent share prices have been trending downward.
