Tech giant Apple has been swatted by the U.S. government lately over e-book price-fixing, while the company has watched its dominance in mobile phones and tablet computing erode as more competitors enter those markets. But for exchange-traded funds that track growth stocks, none of this matters, according to data prepared for Institutional Investor by New Yorkbased financial data firm Axioma. Of the 11 growth ETFs examined by Axioma, eight had Apple as their largest holding.
The iShares Morningstar Large Growth Index Fund (fund A in the chart below), had the largest holding, with 10.94 percent of its assets in the iPhone maker. The Vanguard Mega Cap 300 Growth Index Fund has the second-largest holding, with 8.65 percent. The Vanguard Growth Index Fund, the SPDR S&P 500 Growth ETF and the Schwab U.S. Large-Cap Growth ETF have 6.77 percent, 6.27 percent and 5.77 percent, respectively (see chart 1 below).
To Melissa Brown, senior director of applied research at Axioma, the heavy concentration in Apple shares among some growth ETFs is cause for concern. Apple is a very big stock in the market, so maybe its not that surprising, but it really is betting big on Apple, she says. If youre buying that iShares Morningstar Large Growth Index Fund, for example, thats probably something you should know.Chart 1

Growth ETFs tend to have a high percentage of their assets in technology and consumer discretionary stocks, as chart 2 below shows. But the actual mix of shares in technology and consumer discretionary companies is anything but uniform, according to Axiomas analysis. Apparently, what growth means varies very widely from ETF to ETF, says Brown. Probably even more than with other ETF strategies, the differences here look bigger than any other ETFs weve looked at.Chart 2
Not all growth ETFs, however, are making a big bet on Apple. Three of the funds (the First Trust Large Cap Growth Alphadex Fund, the Guggenheim S&P 500 Pure Growth ETF and the Powershares Dynamic Largecap Growth Portfolio) have no exposure at all to the Cupertino, Californiabased computer maker.
Growth ETFs largely fall into one of two broad strategies, according to Brown. Basically, youve got two different definitions of growth, she explains. One is more stable growth, which would be steady and not extremely volatile. Then theres the cyclical growth, where growth may be higher now but probably contains more volatility.
On the more volatile end of the spectrum, Brown points to iShares Morningstar Large Growth Fund. Although its name wouldnt suggest any particular view on growth, the fund is very tech heavy and very concentrated, Brown says. Apple makes up 11 percent of its portfolio; tech is 35 percent of assets; and the fund is very concentrated, with 80 percent of the portfolio in the biggest 50 stocks.
The Guggenheim S&P 500 Pure Growth ETF falls on the other end of the spectrum, says Brown. The fund doesnt hold Apple shares at all, and its much more heavily weighted in consumer discretionary stocks than technology companies. The Guggenheim ETF has a much higher exposure to momentum than most of the growth ETFs Axioma studied, meaning that the stocks in its portfolio are ones that in general have done well recently, which is not true for all of these portfolios, adds Brown.
Indeed, the growth ETFs exposure to momentum that is, swings in performance by various stocks is another area in which there is some diversity (see chart 3 below). The common wisdom about growth managers is that they tend to be more momentum based, [but] what were seeing here is that this is not the case, says Brown. Its true for some of the funds, but not true for all of them. Some of them seem to have a reasonably high exposure to low-momentum stocks, which is really kind of interesting. You tend to see that more in a value-oriented portfolio.Chart 3
