Is the S&P repeating its pre-dot-com bubble crash pattern?S&P 500SP:SPXCapitalDollarI noticed some coincidence in market movement on the chart between 1997 and 2000 compared to the current movement. High concentration in a few leaders — back then it was internet companies (Cisco, Intel, Microsoft, AOL), now it's the 'Magnificent Seven' (Nvidia, Apple, Microsoft, Alphabet, Amazon, Meta, Tesla). Euphoria around a new technology — back then the internet, now AI. This fuels growth and overvaluation. The Fed keeps interest rates high — the average rate was around 4.5% then and now.
