If I Could Buy Just 1 Stock in November and Hold for 5 Years, It Would Be Alphabet

If a single stock purchase for the long term were possible this month, Alphabet (GOOGL +1.18%) (GOOG +0.73%) would be my top choice. The rationale is straightforward: I believe artificial intelligence (AI) could emerge as one of the most significant investment opportunities in the coming decade, and Alphabet is well-positioned to capitalize on this trend.

However, unlike some companies that rely heavily on AI spending, Alphabet already boasts highly profitable businesses that generate billions in revenue annually. This diversification makes it an appealing candidate for long-term investment.

Alphabet's offerings extend far beyond Google Search. It owns YouTube, Google Cloud, Android, and a suite of widely utilized digital services. These platforms provide access to billions of users and multiple avenues for monetizing AI. The fact that Alphabet has several ways to thrive in the future is a crucial advantage. Unlike many AI investments, Alphabet's investment case is not solely based on future projections.

Even without considering potential opportunities, Alphabet is already a substantial, profitable enterprise. In the third quarter of 2026, revenue grew by 25% year-over-year to $127.6 billion. Operating income increased by 30% to $40.6 billion. Google Cloud demonstrated impressive growth, with revenue more than doubling to $30.7 billion and operating income rising to $11.1 billion from $3.6 billion the previous year. Google Search revenue also expanded by 12%.

These figures highlight a significant point: Alphabet's AI prospects are already translating into tangible business growth, particularly in cloud computing. Moreover, its existing profitable businesses serve as a solid foundation to fund further AI investments. This diversification proves advantageous over a five-year horizon. If one segment of the AI market underperforms, Alphabet's other businesses can still generate revenue and profits.

However, there are reasons to be cautious about overlooking the risks. Developing AI infrastructure is costly. Alphabet is heavily investing in data centers, servers, networking equipment, and other computing resources. In Q3 alone, capital expenditure (capex) amounted to $51.4 billion. This substantial investment drove quarterly free cash flow into negative territory, at $9.1 billion.

Management anticipates capex of $195 billion to $205 billion for the full year 2026, with spending expected to rise again in 2027. This is a considerable commitment. If AI demand continues to grow and these investments yield attractive returns, the spending could strengthen Alphabet's competitive position for years to come. Conversely, if demand falters or computing capacity becomes less valuable than anticipated, the company could end up with expensive infrastructure that takes longer to generate returns.

Additionally, there is a competitive risk. Companies like OpenAI and Anthropic are challenging Google's position in AI. While Alphabet possesses the resources to compete, victory is not guaranteed.

For my investment strategy, I would closely monitor three key areas over the next five years: whether Search maintains its competitive edge, whether Google Cloud continues to grow profitably, and whether AI investments lead to stronger free cash flow. If Alphabet successfully performs in all three areas, its stock would be well-positioned to create significant shareholder value in the next five years.
