Stock price when the opinion was issued
First of all, you have to like energy because any covered call strategy is bullish. He would rather have cash flow. The cash flow from this particular ETF would be a better way to play the energy space than simply buying it outright. However, they are only writing options against 25% of the portfolio each month, so you have some upside. Some of those oil companies do quite well. He is not a believer that a broad-based basket of big-name oil companies are going to do much more than a broad-based basket of big-name goal companies are going to do.
The question is do you want to time the market or be in the market. If you want the yield, and you are okay with some volatility, then these ETFs are nice to hold. Over the next year the sector is probably mostly sideways. He thinks energy stocks will pull back more over the next 6 months.
