Apple Inc. (NASDAQ:AAPL) is in the news lately due to its Worldwide Developers Conference. The event saw the firm take another stab at AI as it launched Siri AI. The software assistant will focus more on voice dictation and provide users with other features, such as answering questions. Apple Inc. (NASDAQ:AAPL) also announced that its AI platform, Apple Intelligence, will play a role in the Safari browser and the Password and Messages applications. Other announcements include visual upgrades to iOS and parental control features.

Earlier, on May 14th, Evercore ISI discussed Apple Inc. (NASDAQ:AAPL)’s shares. The firm raised the share price target to $365 from $330 and kept an Outperform rating on the stock. As part of its coverage, Evercore ISI highlighted factors such as high premiums for the iPhone and a foldable phone.

RiverPark Large Growth Fund discussed Apple Inc. (NASDAQ:AAPL) in its Q4 2025 investor letter:

“AAPL shares rose in 4Q25 following better-than-feared iPhone 17 sell-through trends and stronger Services momentum. The company reported that early adoption of its on-device AI features exceeded internal expectations, particularly in North America and Europe, where attach rates for Pro models remained elevated. Wearables also returned to growth, helped by new health features and improved battery life. While macro softness in China remained a headwind, investors responded positively to evidence of content and advertising revenue re-acceleration within the Services segment, which delivered double-digit growth.

We continue to view Apple as one of the world’s most resilient and profitable businesses, supported by a massive installed base, ecosystem lock-in, and growing high-margin revenue streams. As Apple Intelligence features proliferate across devices, we expect multi-year upgrades, improved monetization, and expanded recurring revenue. With strong cash generation, ongoing share repurchases, and disciplined capital allocation, Apple remains a compelling long- term investment.”

4. Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM)

Citadel’s Stake: $1.4 billion

It will now use NVIDIA’s products, such as cuLitho to streamline the lithography process in chip manufacturing, the Metropolis and TAO toolkits for high-end wafer inspection, and NVIDIA Omniverse for digital twin creation.

Morgan Stanley discussed the firm on June 3rd as it significantly raised the share price target to $1,050 from $520 and kept a Buy rating on the stock. At the heart of the bank’s coverage was the ongoing memory shortage, as it explained that apart from more output, there was no other solution to resolve the market’s tightness.

2. Amazon.com, Inc. (NASDAQ:AMZN)

Baron Durable Advantage Fund discussed Amazon.com, Inc. (NASDAQ:AMZN) in its Q1 2026 investor letter:

“Amazon.com, Inc. (NASDAQ:AMZN) is the world’s largest retailer and cloud services provider. Shares declined 9.8% during the quarter after the company guided to $200 billion in fiscal year 2026 capital expenditures, above Street expectations. While we believe AWS revenue growth will accelerate meaningfully over the next two years, particularly as leading AI companies increase AWS usage, investors are concerned about the impact of sizable incremental investments on near-term profitability. Nevertheless, the company continues to expand operating margins across core North American retail, AWS, and international retail, driven by improved cost discipline and operational efficiencies. Over the longer term, Amazon has substantial room for growth in e-commerce, where it has less than 15% penetration of its total addressable market. Amazon also remains the clear leader in the large and growing cloud infrastructure market, with significant opportunities in application software, including enabling generative AI workloads while its full-stack approach, spanning silicon, systems, software, and developer ecosystem, and hence its competitive moat continues to widen. …” (Click here to read the full text)
