What should investors do? Gaurav Garg, Head - Research, Lemonn, believes that Alphabet’s Q3 results highlight the gap between its AI growth opportunity and near-term profitability expectations. While Google Cloud’s strong performance underscores AI demand, weaker advertising, an earnings miss and negative free cash flow raise concerns over investment returns.

“Its important to remain cautious and wait for the stock to stabilise before considering fresh positions. Existing investors should reassess exposure, as sustained recovery will depend on advertising resilience, cash-flow visibility and capital-spending discipline,” Garg said. Viram Shah, Founder & CEO, Vested, said that in the near term, the stock could remain volatile as investors assess the scale of AI spending and its impact on margins.

“Over the medium term, the outlook will depend on whether Google Cloud can sustain its growth, whether AI strengthens Search monetisation and how effectively Alphabet converts these investments into earnings and free cash flow. The opportunity remains significant, but investors will increasingly demand evidence of profitability alongside growth,” Shah said.
