High valuations of AI-related stocks have been a market focus this week, with concerns over a potential AI bubble dampening investor sentiment. However, Wall Street maintains that certain tech stocks boast solid fundamentals and rapid growth driven by AI, justifying their premium valuations.

Top Wall Street analysts' recommendations can help investors identify AI-related stocks with both strong long-term growth potential and attractive valuations.

According to TipRanks, an analyst performance rating platform, the following three stocks have garnered favor from Wall Street's top analysts.

**Amazon** E-commerce and cloud computing giant Amazon recently reported optimistic Q3 results, impressing investors. The accelerated growth of its Amazon Web Services (AWS) cloud division reinforced Wall Street's confidence in Amazon's AI expansion.

Following Amazon's robust Q3 performance and its recent partnership with OpenAI, Mizuho Securities analyst Lloyd Walmsley raised Amazon's price target from $300 to $315, maintaining a "Buy" rating. TipRanks' AI analyst also rates AMZN as "Outperform" with a $276 target.

Walmsley noted that Q3 results, the OpenAI collaboration, and the promising outlook for Amazon's Trainium chips have strengthened his confidence in AWS's long-term growth. The five-star analyst projects AWS revenue growth to rise from 20% in Q3 to 21% in Q4 2025 and further to 22% in Q1 2026. He also forecasts AWS revenue to grow 23% to $157 billion in 2026 and 22% to $192 billion in 2027—both exceeding Wall Street's estimates of $154 billion (2026) and $185 billion (2027).

"We believe investors will continue adding AMZN shares as its valuation remains below historical ranges, and positive catalysts may extend into early December with AWS re:Invent," Walmsley stated.

He also highlighted cost optimization in Amazon's retail business, driven by automation upgrades in fulfillment centers and logistics network improvements.

Among over 10,100 analysts tracked by TipRanks, Walmsley ranks #103, with a 64% recommendation accuracy and an average return of 27.5%.

**Alphabet** The second pick is Alphabet, parent company of Google and YouTube, which delivered better-than-expected Q3 results, with AI fueling strong growth in its cloud division.

JPMorgan analyst Doug Anmuth raised Alphabet's price target from $300 to $340, keeping a "Buy" rating, while TipRanks' AI analyst sets a $316 target for GOOGL with an "Outperform" rating.

Anmuth emphasized that Q3 marked Alphabet's first $100 billion quarterly revenue milestone, with all major segments posting double-digit growth.

He noted that Q3 performance and positive AI search developments could shift investor sentiment on Google's AI search transition. Alphabet cited AI-driven increases in search queries and paid clicks, while Anmuth added that industry feedback suggests higher conversion rates from Google's AI Overview and AI Mode features.

"AI search was initially seen as Google's biggest risk, but growing evidence suggests it's more of an opportunity than a threat, and this narrative will continue reversing," Anmuth said.

He was also encouraged by Google Cloud's backlog surging to $155 billion, which excludes potential gains from Alphabet's expanded partnership with Anthropic, implying further backlog growth by Q4-end. Anmuth remains bullish, ranking Alphabet as JPMorgan's "second-top pick" after Amazon.

Ranked #113 among over 10,100 analysts on TipRanks, Anmuth has a 63% accuracy rate and 22% average return.

**AMD** The third tech standout is chipmaker Advanced Micro Devices (AMD), which reported strong Q3 FY2025 results, attributing revenue and profit growth to its expanding computing business and rapidly growing AI data center segment.

Stifel analyst Ruben Roy raised AMD's price target from $240 to $280, maintaining a "Buy" rating, while TipRanks' AI analyst sets a $285 target with an "Outperform" rating.

Roy highlighted Q3 revenue growth driven by data center, AI, server, and PC segments. AMD management expects Q4 revenue to rise 25% YoY to $9.6 billion, supported by data center, client, and embedded segments—though gaming revenue declines may partially offset growth.

Interestingly, Roy believes near-term growth will stem from server CPU demand and client CPU market share gains rather than data center AI GPUs. He raised his FY2025 data center AI GPU revenue estimate to $6–6.5 billion from $5 billion.

"Looking ahead, with AMD launching MI400/450 GPUs and Helios racks next year, we remain impressed by its execution," Roy said.

He also expressed optimism about AMD's partnerships with OpenAI and Oracle Cloud Infrastructure, which clarify long-term growth prospects for its data center AI business. Roy anticipates further details on AMD's roadmap and total addressable market (TAM) at its November 11 Analyst Day.

Ranked #20 among over 10,100 analysts on TipRanks, Roy boasts a 71% accuracy rate and 34.4% average return.
