Tech valuations are back to pre-AI boom levels

📝 Discussion Summary (Click to expand)

1. Redefined“tech” sector
The analyst notes that the S&P 500 IT index now excludes Meta, Alphabet and Amazon, which were moved to other sectors.

"The post defines it clearly: S&P 500 Information Technology sector. That excludes Meta, Alphabet, Amazon – which were moved to Communications and Consumer Discretionary." — techkid

2. Changed composition makes historic comparisons misleading
A participant points out that the index’s makeup shifted dramatically after the 2018 re‑classification, so today’s numbers can’t be directly compared to the past.

"This also means that the pre‑2018 index had a fundamentally different portfolio of companies. So comparing today to anything pre‑2018 is apples‑to‑oranges." — kaycebasques

3. Forward‑PE compression likely reflects analyst catch‑up, not a new valuation paradigm
Another user argues that the drop in forward P/E ratios is probably just analysts finally aligning expectations with market prices, and that “ballooned valuations still… because of AI” may be overstated.

"i would imagine theres plenty of ballooned valuations still because of AI" — trueno
