My Favorite ETF Articles Appearing on SA: May 25-26

Since we are now publishing upwards of 10 ETF-specific articles on Seeking Alpha a day, the task of reading through this all can be daunting to even our most dedicated readers. As an editor with a specific interest in the Exchange Traded Products (a broader term that includes ETNs and other difficult to classify products such as the MacroShares Up/Down funds), I decided to take upon myself the task of instablogging what I feel to be 'greatest hits' from our ETF Center.

My opinions in no way reflect those of Seeking Alpha; they're just one man's opinions. I too often miss great articles (I have a two-month old baby so there's no way for me to read it all) and may think something is great while you think it's no big deal.

These pieces all appeared on Seeking Alpha over the last two days (May 25-56):

One of the latest ETF products to pick up steam are Target Date Funds, which seek to provide investors with a 'full' portfolio in a single fund, rebalancing in favor of less risk as the fund's target date approaches. The author goes behind the funds and examines their make-up while pointing out drawbacks such as 'double layering' of expenses and the overlooking of other asset allocation factors other than date of retirement.
