A handful of large technology stocks have garnered attention for outsize returns in recent years. Collectively referred to by the FANMAG acronym, Facebook, Amazon, Netflix, Microsoft, Apple, and Google (now trading as Alphabet) all substantially outperformed the US market1 in the eight calendar years that they have all been public companies (Facebook went public in May 2012).2 Emerging as winners from among a large number of companies that fared less well during 2013–2020,3 these juggernauts bested most of their surviving peers with annualized outperformance versus the US market ranging from 7.31 (Alphabet) to 42.58 percentage points (Netflix), as shown in Exhibit 1.

Key Contributors
Past performance is no guarantee of future results. In USD. Data from CRSP and Compustat for time period 1927–November 2020.

If history is any guide, the FANMAG acronym will eventually be replaced by another trendy name. For example, stock market historians will remember the Nifty Fifty in the 1960s and 70s, a set of 50 blue-chip stocks like Coca-Cola and General Electric. The early 2000s witnessed increasing adoption of the acronym BRIC, representing investment opportunities in the fast-growing emerging economies of Brazil, Russia, India, and China. More recently, the WATCH companies—Walmart, Amazon, Target, Costco, and Home Depot—have also gained traction in the market’s lexicon.
While documenting trends in finance is entertaining, there is little evidence that investors can spot these trends in advance in a way that would enable market-beating performance. Moreover, concentrated bets on high-flying stocks can expose investors to idiosyncratic risks and a wider range of possible outcomes. By contrast, a sound investment approach based on financial science emphasizes the importance of broadly diversified portfolios that provide exposure to a vast array of companies and sectors to help manage risks, increase flexibility in implementation, and increase the reliability of outcomes.
