NEW YORK (ETF Expert) -- In this commentary, I am choosing to look at some alternative asset exchange-traded funds. They are often misunderstood, rarely discussed in detail and they may go the furthest toward reducing overall portfolio risk.If the "fit hits the shan" the way it did in the financial collapse of 2008, then most asset classes (e.g., most stock types, most bond types, most REITs, most currencies, most commodities, etc.) could depreciate significantly. Alternative assets may or may not do much better, but when it comes to a world where the Fed is likely to remain exceptionally accommodative, "alt assets" are worthy of discussion. Here are three exchange-traded investments for tapping into a world of alternative possibilities: 1. ETRACS Wells Fargo Business Development Company Index Note ( BDCS). Business Development Companies (BDCs) are similar to venture capitalists and private equity firms. In particular, there are roughly 30 or more publicly traded corporations that engage in lending at high yield rates to smaller up-n-comers; BDCs often garner equity stakes as well. The Securities and Exchange Commission requires these BDCs to invest 70% of assets in U.S. companies, while distributing a minimum of 90% of taxable income in the form of dividends. Those distributions often lead to annual yields in the 7%-9% range for shareholders. Not surprisingly, there are exchange-traded vehicles for BDCs. The unleveraged ETN from UBS E-TRACS, ticker symbol BDCS, is a means for accessing the alternative asset class. Capital appreciation may be a little light in 2013, though the 7% annualized yield is a nice offset; rising interest rates in the May-June period did not hurt BDCS more than the market at large. Moreover, the 50-day moving average has remained above the 200-day moving average since early in 2012.
However, there is very little discernible performance difference or price direction when compared to the S&P 500 SPDR Trust ( SPY). Both have three-year total returns of roughly 58%; both move in the same direction 99 times out of 100. The advocates of 130/30 strategies swear by the approach's ability to deliver excess returns for less risk, but the evidence is pretty slim... at least in the passive world of ETF indexing. 3. Credit Suisse Merger Arbitrage Index ETN ( CSMA). In merger arbitrage, one is pursuing the spread between the stock price of a target company after the public announcement of its proposed acquisition and the price offered by the acquirer to pay for the targeted company's shares. If a deal goes through as anticipated, gains are probable. If a deal fails to materialize, losses may occur. Compared to the previous "alt" assets, CSMA provides the least annualized volatility and the lowest correlation with the S&P 500 with a coefficient of 0.39. In the same vein, however, the investment may not provide much of anything of value. Over the previous three years, the profits are frighteningly slim.
For the most part, alternative ETFs may not be alternative enough. And when they are, they may not provide enough value to warrant their inclusion. That means the majority of ETF enthusiasts should stick with mainstream offerings tied to stocks, bonds, REITs and commodities. Moreover, since few of the primary asset classes will hold up in a systemic shock, you'll need to actively manage the downside risk with an approach to lowering your overall exposure.
