ETFs: What Happens if Apple Splits, Enters the Dow?

One of this week's big rumors involves none other than Apple

AAPL

, the largest U.S. company by market value. On Tuesday, Sanford C. Bernstein & Co. published a research note saying the iPhone maker is mulling a stock split that could lead to its stock being added to the venerable Dow Jones Industrial Average. Bernstein said Apple's decision to initiate a dividend earlier this year makes it more likely the stock could be added to the blue chip index. "Apple's initiation of a dividend brings the company in line with all other Dow components. We note that Apple is currently the only company above $215 billion in market cap that pays a dividend and is not included in the Dow," Bernstein analyst Toni Sacconaghi

said in the note, according to Bloomberg

. How an Apple split, if the event comes to pass, would impact ETFs remains to be seen. For starters, one ETF that could immediately be impacted by the split and ensuing speculation that Apple is headed for the Dow is the SPDR Dow Jones Industrial Average

DIA

. Currently trading just over $600 a share, Apple is a tough addition for the Dow, a price weighted index. International Business Machines

IBM

, which trades for just under $200, is DIA's top holding at 11.4 percent. In theory, if Apple went into the Dow today, it would account for over a third of the index's weight based on its lofty price tag. "Apple, with a $600 handle, would have undue pressure on the DJIA index itself on a daily and intraday basis," said

Paul Weisbruch of Street One Financial. The last time the Dow added new constituents was in 2009 when Citigroup C and General Motors GM were booted during the financial crisis. Cisco Systems CSCO and Travelers TRV replaced Citi and GM. The Bloomberg piece notes Apple declined to comment on the split, so there is no way knowing what the company's plans are at this point. On the other hand, it is not unreasonable to speculate that if Apple engineers a 10-for-1 split of its shares at $600, thereby reducing the price to $60, retail investors that have been kept at bay by the stock's huge price tag would flood into the stock. Since most passively managed ETFs use a weighting methodology based on the market capitalization of the funds' holdings, Apple would still be the largest holding in marquee ETFs such as the PowerShares QQQ QQQ and the Technology Select Sector SPDR XLK. Taking things a step further, it is important to note that those ETFs and others

have been used as proxies on Apple

because the funds have large weights to the stock and reasonable price tags. To that end, a possible argument is that QQQ, XLK and the iShares Dow Jones US Technology Index Fund

IYW

, the ETF with the largest weight to Apple, would initially suffer as investors depart the ETFs in favor of direct ownership of Apple shares. Not so fast. It is demand for or selling pressure on an ETF's underlying components that drives the fund's price action. Assuming Apple splits 10-for-1 and the retail crowd comes running into the stock, IYW, QQQ, XLK and other ETFs are apt to benefit, not suffer. At the very least, these ETFs might be a little more active than usual as the Apple split rumor floats around. "It is also fair to say that as AAPL goes, the entire Tech sector goes as AAPL has a 19.63% weighting in XLK for instance, with the next highest weighted stock, IBM, coming in at only 8.14 percent," Weisbruch said in a research note published today. "ETFs that have significant exposure to Apple that may be very active in the short term and are certainly worth monitoring include, IYW, the Focus Morningstar Technology ETF

FTQ

, the Vanguard Information Technology ETF

VGT

and the iShares S&P Global Technology Index Fund
