Both are in cloud and AI computing power; one has its own cash flow as a safety net, while the other relies purely on financing for expansion. The data center sector adjusted as a whole that day, with ST/US/AMZN hardly affected, while ST/US/NBIS absorbed a double-digit drop in a single day.

The beta of AI computing power ultimately comes down to what's written on the balance sheet: ST/US/AMZN's capital expenditures are supported by cash flows from retail and advertising, so when prices fall, the market knows it can withstand it; ST/US/NBIS's expansion relies entirely on external financing, so any shift in interest rates or risk appetite requires a revaluation of its valuation. It has already fallen 15% below the 50-day moving average, representing a 33.8% decline from its 60-day high. The volatility of pure computing power plays is at this magnitude; how much exposure would you allocate to such positions?
