Share-split context: This ETF has both forward- and reverse-split history. The most recent recorded event was on Apr 15, 2020 with coefficient 0.05. Current price-return figures are already split-adjusted. Forward splits receive no automatic performance penalty; reverse-split history remains a separate structural warning.

What this ETF is trying to do

The VANECK OIL SERVICES ETF (OIH) is an exchange-traded fund designed to track the oil services industry. Instead of investing in a single company, this ETF provides exposure to many different companies that support oil and gas operations. Based on its top holdings, the fund focuses heavily on large energy service providers like SLB LTD and BAKER HUGHES CO CLASS A.

What the numbers show

The performance data for OIH shows significant growth over various timeframes. As of October 7, 2026, the current share price is $381.54.

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 33.98%. The one-year price return was approximately 44.52%, and the three-year price return was approximately 17.37%.

• Total Return: This includes both the share price changes and the impact of distributions. The YTD total return is approximately 33.98%. The one-year total return was approximately 46.99%, and the three-year total return was approximately 23.54%.

Because this ETF has a history of both forward and reverse splits, the historical price data is provided as split-adjusted returns to ensure accuracy.

Income and distribution explanation

OIH provides cash distributions to investors, with a trailing distribution amount of $4.869. The distribution yield is approximately 1.28%. This yield represents the cash paid out relative to the current share price.

It is important to note that the distribution frequency for this ETF is described as "irregular" or "less frequent." This means investors should not expect a regular, predictable schedule of payments.

NAV erosion explanation

"NAV erosion" refers to a decline in the Net Asset Value (the actual value of the assets held by the fund). 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.

However, regarding price-based evidence, the fund has an erosion score of 100, which is labeled as "No price erosion detected." The erosion severity is rated as "good," and there is no severe erosion-risk flag present.

Pros

• Strong Growth: The fund has shown high one-year and year-to-date total returns.

• Healthy Price Trend: The erosion score suggests there has been no significant price erosion detected.

• Industry Focus: It provides concentrated exposure to major players in the oil services sector.

Cons

• Irregular Income: Distributions are not frequent or regular, which may make it difficult to rely on for steady cash flow.

• Sector Concentration: Because it focuses on oil services, its performance is closely tied to that specific industry.

Beginner takeaway

OIH is an ETF focused on the oil services sector that has recently seen strong price and total returns. While it pays distributions, they are irregular rather than frequent. Investors should remember that a distribution yield is a measure of cash paid out and is separate from the total return of the investment.
