Looking for a Unique ETF? This One Is More Valuable As a Warning.
When the first exchange-traded fund (ETF) was created, it was built to track the S&P 500 index. Following that success, Wall Street brought out more products that tracked other broad-based indexes.
However, the finance industry has a habit of pushing the limits, and an increasing array of highly focused ETFs were soon created. Many have done well, but not all of them have been good choices for investors.
A great example of that today might be AltShares Merger Arbitrage ETF (NYSEMKT: ARB).
