Dimensional Perspectives

The stocks commonly referred to by the FAANG moniker—Facebook, Amazon, Apple, Netflix, and Google (now trading as Alphabet)—have posted impressive gains through the years, with all now worth many times their initial-public-offering prices. The notion of FAANG stocks as a powerful group holding sway over the markets has sunk its teeth into some investors. But how much of the market’s recent returns are attributable to FAANG stocks? And does their performance point to a change in the markets?

Over the 10 years through December 31, 2018, the US broad market1 returned an annualised 13.4%, as shown in Exhibit 1. Excluding FAANG stocks, the market returned 12.6%. The 0.8-percentage-point bump resulted from the FAANGs collectively averaging a 30.4% yearly return over the decade.

With FAANGs portfolio formed each month including common stocks listed on NYSE, NYSE MKT, and NASDAQ. Stocks are weighted by market capitalisation. Without FAANGs formed similarly but excluding Facebook, Apple, Amazon, Netflix, and Alphabet (Google).

Investors may be surprised to learn that it is actually common for a subset of stocks to drive a sizable portion of the overall market return. Exhibit 2 shows that excluding the top 10% of performers each year from 19942 to 20183 would have reduced global market performance from 7.2% to 2.9%. Further excluding the best 25% of performers would have turned a positive return into a relatively large negative return.

Diversification does not eliminate the risk of market loss. Past performance is no guarantee of future results. “All stocks” includes all eligible stocks in all eligible developed and emerging markets at their market cap weights. Eligible stocks are required to meet a minimum market capitalization requirement. REITs and investment companies are excluded. Compound average annual returns are computed as the compound returns of the value-weighted averages of the annual returns of the included securities. “Excluding the top 10%” and “Excluding the top 25%” are constructed similarly but exclude the respective percentages of stocks with the highest annual returns by security count each year. Individual security data are obtained from Bloomberg, London Share Price Database, and Centre for Research in Finance. The eligible countries are: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Republic of Korea, Malaysia, Mexico, Netherlands, New Zealand, Norway, Peru, Philippines, Poland, Portugal, Russia, Singapore, South Africa, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, the UK, and US.

This lesson also applies to capturing the premiums associated with a company’s size and its price-to-book ratio. Research by Eugene Fama and Kenneth French (“Migration,” 2006) provides evidence that these premiums are driven in large part by a subset of stocks migrating across the market.

Research has shown no reliable way to predict the top-performing stocks. Looking at the top 10% of stocks by performance each year since 1994, on average less than a fifth of that group has ranked in the top 10% the following year.

The tendency for strong market performance to be concentrated in a subset of stocks is therefore also a cautionary tale about the importance of diversification—investors with concentrated portfolios may actually miss out on the very stocks that deliver the best of what the market has to offer. An investment approach built around broad diversification can help achieve a more reliable outcome for investors over the long term—sharp acronym or not.

RISKS
Investments involve risks. The investment return and principal value of an investment may fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original value. Past performance is not a guarantee of future results. There is no guarantee strategies will be successful. Diversification neither assures a profit nor guarantees against loss in a declining market.
