From time to time I see financial writers lamenting the explosion in ETF popularity over the last few years. They complain that the original idea of index investing (i.e., buying and holding a low-cost, diversified portfolio) has been perverted in favor of a focus on trading ETFs for short-term profits.
Frankly, I disagree. I think the proliferation of ETFs has, on the whole, been great for investors.
(Quick note: I’m not arguing that ETFs are better than the index funds that already existed. Nor am I saying that most investors should be buying ETFs on margin, day trading them, or buying sector-specific ETFs.)
More Access to Low-Cost Investments
A couple decades ago, pretty much the only way to build an indexed portfolio was to have an account at Vanguard. Today, anybody with a discount brokerage account has access to the tools with which to put together a low-cost, diversified portfolio.
Is that bad for investors?
Price Competition
Over the last year or so:
- Schwab created their own commission-free ETFs,
- Fidelity responded by working out a deal with iShares to offer commission free trades on iShares ETFs, and
- Vanguard eventually replied by allowing for commission-free trades of Vanguard ETFs.
It’s price competition in action, and I doubt it would have happened if it weren’t for the massive demand for ETFs.
Is that bad for investors?
Cost Awareness
We’re naturally cost-conscious in most areas of their lives. We do our best to save money on groceries, utility bills, back to school supplies — everything. Everything, that is, except for investments.
For decades, investors have been paying through the nose for mutual fund portfolios. And we’ve been doing it without even realizing it.
That’s finally changing. More and more investors are becoming cost-conscious about their portfolios. And ETFs are (at least in part) to thank for that.
For example, when Fidelity and Schwab each promoted their commission-free ETFs, they promoted the low-cost aspect of it. There were full-page adds in financial magazines encouraging investors to pay attention to expense ratios and commissions per trade.
Is that really so bad?
