Big Tech AI vs AI Semi Market Cap

67
[The Story Behind This Indicator]

Recently, Big Tech stocks have faced downward pressure due to growing concerns over whether they can sustain massive AI CapEx and ultimately achieve monetization. In contrast, AI-related semiconductor stocks—the direct recipients of these investment funds—are rebounding and gaining momentum.

Some market participants compare this flow to the Dot-com bubble era. I created this script to track in real-time whether a true "Market Cap Flipping" (reversal) is occurring between the AI Service providers (Big Tech) and the AI Infrastructure providers (Semiconductors).

[How It Works]

This indicator aggregates and compares the total Market Capitalization (Price × Shares Outstanding) of two distinct groups:

🟦 Big Tech (AI Solutions & Services): The companies spending heavily on AI infrastructure.

🟧 AI Semiconductors (Hardware & Infra): The companies benefiting from Big Tech's CapEx.

[Key Features]

Real-time Comparison: Visualizes the aggregate value of both sectors on a single chart to spot divergence or convergence.

Cap Flipping Watch: Easily identify if the "Hardware" sector's valuation overtakes the "Solution" sector.

Percentage Ratio: Displays a label showing the Semiconductor sector's size relative to Big Tech (e.g., "Semi is 60% of Tech").

Customizable Tickers: You can toggle individual companies On/Off in the settings to adjust your basket.


[Included Tickers (Default)]

Big Tech: MSFT, GOOGL, AMZN, META, AAPL, TSLA, PLTR, ORCL, ADBE

AI Semi: NVDA, TSM, AVGO, AMD, MU, ARM, ASML, ANET, MRVL

[Usage Note]

If the Orange Line (Semi) rises while the Blue Line (Tech) falls/stagnates, it indicates the market is favoring "Infrastructure Builders" over "Service Providers."

Use this to gauge the maturity of the AI investment cycle.
