NEW YORK (
) -- They've become wildly popular.
Their assets grew more than 30% a year during the past decade. By comparison, mutual funds saw their assets rise just 5%-6% per year, according to McKinsey & Co.
And there are no signs of that growth slowing down. McKinsey & Co. projects assets in these securities will more than double in the next five years to at least $3.1 trillion, from a little more than $1.5 trillion today.
I'm talking about exchange-traded products. Most of that growth is in exchange-traded funds, but this market also includes a handful of overlooked exchange-traded notes that yield up to 16%.
And while there are ETFs for everything from copper to cocoa, ETNs offer a unique type of exposure to mainly two high-yield groups: master-limited partnerships and business-development companies.
For example, there is the
JPMorgan Alerian MLP Index ETN
, which yields 5% and tracks the performance of a basket of 50 master limited partnerships. And there's the
UBS ETRACS 2x Wells Fargo BDC
, which pays a yield of 16% and tracks 26 BDCs.
ETNs are an entirely different beast from ETFs. Both track the performance of an index and offer a simple way to move in and out of a sector. Both may pay dividends thrown off by the securities in the index they track. And both can be bought or sold during the day, just like a stock.
But that's where their similarities end.
Unlike ETFs, ETNs do not represent a claim stocks, bonds, or commodities. The ETN issuer, which is usually an investment bank such as
, may invest in the index companies to collect returns, but ETN holders like you and me don't have a claim on those assets.
Instead, ETNs are promissory notes. They are senior unsecured debt that promises to match the return of a specific benchmark.
Like bonds, ETNs have a maturity date. At maturity, generally 15 to 30 years from the issue date, the ETN is redeemed. Unlike bonds, however, you don't receive the face value in cash. Instead, the amount you receive is based on the performance of the index. What you get at maturity depends on how well the index has performed.
