Lessons for investors from Big Tech's previous golden era

The forerunners of today's tech stock titans dominated the 1960s and 1970s. Former Xerox senior manager Dr Mike Tubbs was there and explains what investors can learn from those companies' mistakes.

Investors often fail to appreciate just how big Big Tech is. The world’s four largest technology stocks –Alphabet, Amazon, Apple, and Microsoft – account for around 21% of the market capitalisation of America’s S&P 500 index. In other words, just 0.8% of the index’s companies comprise more than a fifth of the index.

But this isn’t the first time huge, fast-growing tech shares have dominated stockmarkets. The 1960s and early 1970s marked another Big Tech era. Markets were in thrall to the Nifty-50, 50 fast-growing large-caps that captured the headlines. Four of them were famous tech stocks: IBM, Kodak, Polaroid and Xerox. Their history, and the parallels we can draw with today’s market backdrop, hold valuable lessons for the investors and tech titans of the 2020s.
