FYI: The harsh truth of trading is this: Not every ETF can or will have a pennywide spread. But for large, well-traded ETFs, most investors expect trading costs to be relatively constrained—an expectation that is usually met.
Usually.
For there are a few exceptions to this rule. A handful of large, well-traded ETFs—as in, more than $100 million in assets under management, trading more than $10 million in daily average volume—carry surprisingly high spreads. Understanding why is an exercise in due diligence, and a reminder that if a metric sounds too good to be true, it just might be.
