With Treasury yields seemingly hitting new lows on a weekly basis, many investors have become desperate for higher levels of current income.

This has pushed many into ETFs that have a focus on yield, such as junk bond funds, MLP products, and more traditional equity exchange-traded securities.

These include funds that zero-in on mainstays of the dividend world like utilities or firms that have a long history of raising their payouts over time.

Unfortunately, many of these products have become ultra-popular and thus crowded trades. In fact, from a year-to-date look, ETFs that promise high yields have dominated the fund flows reports, with products targeting bonds – LQD , JNK, and HYG – preferred stock —PFF — mortgage-backed securities — MBB — and MLPs — AMJ —all adding more than USD1bn dollars in assets since the start of 2012.

However, not all dividend-focused products have been created equal nor have they received the same amount of buzz. Instead, a number of products targeting high yield securities are still overlooked despite offering up sizeable yields.

Furthermore, many of the overlooked funds are in sectors which have modest correlation levels to the aforementioned segments, suggesting that these glossed-over products could also help from a diversification perspective as well.

With this backdrop and an increased focus on yield by many investors, Zacks Investment Research has highlighted three funds which payout at least twice as much as the S&P 500, but have not received anywhere near the attention that many of their high yielding counterparts have. In fact, all three have less than USD250m in AUM, a paltry figure compared to what many of the aforementioned funds have pulled in just this year.
