The fund follows a buy-write strategy, purchasing U.S. and global equity ETFs while simultaneously selling call options to collect premium income. Its fund-of-funds structure provides broad asset allocation benefits.

It suits income-oriented investors who want lower volatility than a simple index investment and who value regular cash flow.

It is an actively managed ETF launched in 2015 by Main Management.

The fund selects ETFs in undervalued sectors or asset classes and sells call options against those holdings to secure downside protection and additional income. The proportion of options sold is adjusted flexibly depending on market conditions.

• Sector-level asset allocation through a fund-of-funds structure
• An active strategy in which the portfolio manager adjusts weightings at their own discretion, without a fixed index

Assets under management (AUM) stand at $1.5B, and the expense ratio is 0.99% per year.

Like IDUB and VEGA shown in the table, it uses option premiums, but it is not limited to a specific theme. Instead, it builds a portfolio spanning all market sectors to spread risk.

In sideways markets or periods of moderate gains, the fund has maintained solid results relative to the market thanks to option premium income, and it has shown defensive behavior when market volatility rises.

As interest rate volatility increases and investors demand more income, inflows into covered call ETFs that offer stable dividends have continued at a steady pace.

Its strengths are stable monthly dividends and low volatility, but gains can be capped in sharp rallies, and its management fee is somewhat high.

IDUB and KLIP in the table are covered call products specialized in particular sectors or themes, while VEGA offers broad access to global assets. For a more popular and larger alternative, there are large active income ETFs such as JEPI and JEPQ. For those who prefer a mechanical index-tracking approach, QYLD, XYLD, and RYLD, which are based on the Nasdaq and S&P 500, are also worth considering.

BUYW is a hybrid product that combines the growth potential of equities with the income potential of options. Before investing, you should clearly understand how a covered call strategy responds to different market conditions.

A covered call strategy is not a guarantee that fully protects principal when prices fall, and investors should keep in mind that in strong rallies the fund may lag the returns of the market index.

It is a suitable tool for retired or conservative investors who want to generate stable cash flow while managing asset volatility. However, they should consider that the pace of long-term asset growth may be slower than that of the index.
