Applying the Relative Strength Index (RSI) to the AI Infrastructure Trade

To understand the market reaction described in the article, we can apply the Relative Strength Index (RSI), a momentum indicator that measures the speed and magnitude of recent price changes to determine if a stock is overbought (typically an RSI above 70) or oversold (typically an RSI below 30).

Here is how the RSI scenario would unfold for semiconductor, memory, and data-center stocks based on the article's events:

Phase 1:

The Overbought Climax (RSI > 80) In the months leading up to this article, the relentless narrative of unchecked AI spending—driven by the top four hyperscale’s pouring $168 billion into capital expenditures—created a massive demand vacuum. Stocks like Nvidia, Micron, and data-center power suppliers (like Caterpillar) experienced sustained, aggressive buying. On the RSI chart, this relentless upward price action with little pullback pushed the momentum indicator deep into overbought territory (e.g., an RSI of 85). The trade was highly extended, but as long as the "AI spending euphoria" continued, high RSI levels were ignored.

Phase 2:

The Catalyst and Mean Reversion (The RSI Plunge) The article notes the emergence of a new narrative: rationalization. When the Bloomberg report broke that Meta might rent out excess capacity—a tacit admission of potential "overbuilding"—it struck at the core thesis of infinite AI demand.

Technically, this fundamental shock triggered a massive mean reversion. The sharp sell-offs (11% for semiconductors, 15-17% for memory stocks in just two days) represent a violent shift in momentum. On the RSI chart, this sudden drop in price would cause the indicator to plummet sharply from 85 down to the 50 to 60 range (neutral), or potentially even dip toward 30 (oversold) in the case of the hardest-hit memory stocks. The RSI successfully signaled that the short-term upward momentum had collapsed.

Phase 3:

The Earnings Crossroads (Divergence vs. Confirmation) The article concludes by pointing to upcoming earnings reports as the critical juncture to see if AI investment growth is plateauing. This is where the RSI scenario splits into two potential outcomes:

• Scenario A: Bullish Divergence (The Pullback is a Buying Opportunity) If the hyperscale’s report earnings indicating that the $168B spending is sustained and accelerating toward the projected $1 trillion in 2027, the price of AI stocks will bottom and begin to rise again. Even if the price is still near its recent lows, the RSI will curl upward. This creates a bullish divergence (price is low, but momentum is turning positive), signaling to traders that the overbought purge was just a healthy reset, and the AI capex rally is back on.
• Scenario B: Bearish Momentum Confirmation (The Capex Plateau) If earnings reveal that Meta, Google, and Microsoft are indeed tapping the brakes on capex growth due to "overbuilding," the RSI will fail to find a foothold. After a brief dead-cat bounce, prices will continue to slide. The RSI will remain suppressed below 40, rejecting any upward momentum. This would confirm that the initial overbought selloff wasn't just a correction, but the beginning of a prolonged bearish trend for the AI infrastructure trade as the "law of very large numbers" finally catches up to the sector.

Summary:

In this scenario, the RSI acts as a leading warning system. The extreme overbought conditions made the sector highly vulnerable to the "excess capacity" narrative, and the upcoming earnings will dictate whether the RSI plunge was a momentary reset or the start of a structural breakdown.
