The hidden perils of ETFs
You can save money and diversify with these cheap index funds, but watch out for the pitfalls.

Danger: Fund companies are throwing a lot of ETF ideas up against the wall -- one tracks companies with lots of valuable patents -- and not all of them will stick. Over 50 funds shut down last year, leaving investors to find a new place for the cash (and possibly owing capital gains taxes). To avoid headaches, stick to established ETFs with assets of $30 million or more.
