ETFs For GM's Sequel? Maybe, Maybe Not

Alright, General Motors GM has finally graced us with its IPO and sequel as a public company. For investors looking to play the potential success of GM the sequel without jumping directly into that stock, derivative plays are few and far between. Ford F immediately jumps to mind, but what about ETF plays? GM isn't in any ETFs yet and it will take a little while for the stock to make its way into the S&P 500, so where do ETF investors turn to benefit from GM's success, assuming that success is realized? One option would be the thinly traded PowerShares Active Mega Cap ETF PMA. Ford accounts for more than 6% of this fund's weight. Another option would be the Consumer Discretionary Select Sector SPDR XLY of which Ford is a top-10 holding at 4.7%. Don't bother stretching too auto parts suppliers through ETFs because companies like American Axle AXL and Borg Warner BWA don't account for even 2% of any of the ETFs that they're found in. All this makes the Professor think if GM performs well, it's high time for an auto-specific ETF.
