24/7 Wall St.

With looming interest rate increases, all the bond proxies have been hit hard. Utilities, real estate investment trusts (REITs) and energy master limited partnerships (MLPs) all had a very tough first half of 2015. A new research note from Deutsche Bank says that utilities are cheap, and all the quality companies yielding 4% or more make very good sense for the last half of 2015. Other top Wall Street firms are starting to join in the chorus for the utility stocks.

The Deutsche Bank team expects the Federal Reserve to start hiking rates in September and continue through 2016. They also think the climb in long-term yields will be limited, the yield curve actually flattens and fed funds will be at 2% and the 10-year Treasury yield at 3% by the end of 2017. If they are correct, then utilities are a great place for yield investors to stay put or initiate positions in.

The Deutsche Bank team makes solid points when they remind investors that utilities have little if any currency issues, have better dividend support than telecoms, have the lowest sector price-to-earnings (P/E) ratio at 15.5, and the dividends are taxed as dividend income instead of ordinary income, like REITs and MLPs. These are all very good reasons to stay with them now, or add to portfolios seeking income and safety.
