Why did the Microsoft share price drop about 10% today?

The market focused on rising AI capex and the timeline for returns, not the earnings beat. Capex-to-revenue is 27.20% and capex-to-operating cash flow is 51.77%, which pressured free cash flow. That reset expectations after a strong rally, driving a broad de‑risking in MSFT stock despite healthy margins and Azure demand.

Is Azure growth slowing, and does it threaten the thesis?

Analysts still see robust Azure AI demand, but investors are debating sustainability from here. After a big run, even solid growth can be judged harshly. The thesis rests on durable cloud adoption and monetisation of AI workloads. If management shows improving returns on AI spend, sentiment toward the Microsoft share price can stabilise.

What key levels should traders watch after the drop?

Technically, the 50‑day moving average near US$479.20 and the 200‑day near US$485.50 are key. Bollinger Bands sit around US$471.42 to US$491.59, with ATR at 7.92 highlighting wider swings. RSI at 45.34 signals neutral momentum. A sustained hold above the middle band near US$481.51 would be constructive for the Microsoft share price.

How should Australian investors think about currency and ETFs?

Most US shares trade in USD, so FX can add or subtract from AUD returns. Moves in the Microsoft share price can ripple through Nasdaq‑tilted ETFs that hold MSFT. Consider FX costs, rebalancing schedules, and position sizing. Long‑term investors often prefer staged entries rather than lump sums when volatility is elevated.
