This is exactly the strategy to employ at market tops. You want broad market exposure along with some different alternative strategy funds in your portfolio to complement your trades.
This ETF has a very interesting strategy and it has just launched. I would not worry about the track record for the construction is solid, low expense ratio 0.35%, a dividend yield of 8.34%. It's composed of a wide variety of high-quality, low volatility stocks while also selling calls.
I took a look at the holdings and they include some NDX and some SPX names. It gives you a wide variety of exposure from Chubb and Deere to Elly Lilly and Google, and it appears currently they are selling calls against the SPX. So this, combined with the monthly payout of a dividend and the hedge it provides gives you income and stability. The dividends can either be reinvested, spent, or use for new opportunities.
