Is Microsoft at risk if the AI bubble 2026 bursts?

There is risk to valuation if sentiment turns, since Microsoft trades at 34.52x earnings. The buffer is strong cash generation, low leverage, and sticky enterprise demand. Watch Azure AI growth rates, pricing commentary, and capex guidance. If utilisation improves, cash flows can still compound even with lower multiples.

How large is Microsoft AI capex and is it sustainable?

Capex equals 23.49% of revenue and 46.94% of operating cash flow. That is heavy, but interest coverage is 54.35 and debt-to-equity sits near 0.17. Sustainability depends on workload growth and pricing. Rising utilisation and premium services should allow capex intensity to moderate while free cash flow expands.

What should UK investors watch into results?

Focus on Azure AI revenue growth, gross margin mix, and capex trajectory. Look for updates on the $135bn OpenAI exposure, customer commitments, and long-term contracts. Technicals matter too: price versus the 50-day and 200-day averages. Any change in capital returns, like buybacks or dividends, will also shape sentiment.

How can I manage Magnificent 7 concentration in my portfolio?

Check fund top holdings and sector weights, then set maximum position sizes. Rebalance periodically, add diversifiers, or use equal-weight funds to reduce megacap bias. Dollar-cost averaging helps with timing risk. Keep decisions tied to operating data and valuations rather than headlines about cycles or bubbles.
