ETF Education Report: GRANITESHARES YIELDBOOST TSM ETF (TMYY)

What this ETF is trying to do

The GRANITESHARES YIELDBOOST TSM ETF (ticker: TMYY) is an exchange-traded fund listed on the NASDAQ. This specific ETF is categorized as an "option income" fund. This means it uses certain financial strategies, often involving options, to try and generate extra cash for investors.

What the numbers show

As of September 24, 2026, the current price of one share is $22.15.

It is important to note that total-return data (which includes both price changes and distributions) and specific price-return percentages (like one-year or year-to-date returns) were not supplied in the current data. Because this information is missing, we cannot see how much the share price has moved up or down over specific time periods.

Income and distribution explanation

This ETF focuses heavily on providing cash to investors. The distribution yield is approximately 30.40%. This number describes the amount of cash distributed relative to the current share price.

In the last 12 months, the fund made 23 distributions, totaling approximately $6.73 per share. These payments usually happen on a monthly basis, and the data shows they most often occur on Fridays.

A note on high yields

When you see a very high distribution yield, like 30.40%, it is important to remember that a high yield alone can be misleading. A high yield tells you how much cash was paid out, but it does not tell you if the total value of your investment grew or shrank.

NAV erosion explanation

"NAV" stands for Net Asset Value, which is essentially the underlying value of the fund's assets. "NAV erosion" happens when the value of those underlying assets decreases over time.

While some investors worry about erosion when they see high payouts, there is no "severe erosion-risk flag" for this ETF in the current data. However, because the erosion score is withheld due to insufficient verified price history, we cannot provide a specific measurement of erosion risk at this time.

Pros

• High Cash Flow: The fund has a high distribution yield of approximately 30.40%.

• Frequent Payouts: The fund provides regular cash through distributions, which occur 23 times over the last year.

Cons

• Missing Performance Data: There is no supplied data for price returns or total returns, making it hard to see the historical trend of the share price.

• Missing Holdings Data: No specific top holdings were provided in the current report.

Beginner takeaway

TMYY is an option-income ETF that offers a high distribution yield and frequent cash payments. However, because the price return and total return data were not supplied, a new investor cannot see how the share price has performed historically. Always remember that high cash distributions do not guarantee that the value of your original investment will stay the same.
