Alphabet’s Dow Debut Shows Index Headache in Tech-Driven Economy

Alphabet Inc.’s addition to the Dow Jones Industrial Average marks another step in the benchmark’s effort to catch up with a market increasingly defined by Big Tech.

The inclusion of the search giant’s parent company, announced Tuesday by S&P Dow Jones Indices, extends a years-long effort to modernize the 30-stock average after criticism that it failed to keep pace with the technology companies driving much of the market’s gains.

Alphabet will replace Verizon Communications Inc. before trading begins June 29, according to a press release from S&P Dow Jones Indices, following the relatively recent additions of Nvidia Corp. and Amazon.com Inc.

“Better late than never,” said Richard Moroney, chief investment officer at Horizon Investment Services and editor of Dow Theory Forecasts. “This move reflects an effort on the part of S&P to make the Dow Industrials more relevant in an era where technology and AI-related stocks dominate the stock market.”

For supporters, the move helps bring the Dow closer to the economy investors actually see today. For critics, it is another reminder that the century-old benchmark often adapts only after the market has already been transformed.

That tension has followed the Dow for years.

Unlike the S&P 500 and Nasdaq 100, which are weighted by market value, the Dow remains a price-weighted index, a structure that historically made it difficult to add high-priced technology stocks because of the outsized influence they would have on the gauge. Stock splits at companies including Amazon and Alphabet helped remove one obstacle to their eventual inclusion.
