A company called Nvidia gives their workers special money that they can use to buy parts of the company. This special money is called a "stock grant". Some people think these stock grants are so valuable that they can let workers buy big expensive things, like yachts. But not everyone keeps the stock grants and some sell them instead. Nvidia's value has grown a lot over time, more than Tesla's value. Tesla also gives their workers stock grants but they have not sold as much of their company yet. Some people think this is one reason why Tesla workers are happy and do not want to join a union. Read from source...

- The title is misleading and sensationalized. It implies that Nvidia and Tesla employees are able to buy yachts solely because of their stock grants, which is not true or supported by any evidence in the article.
- The article focuses too much on the past performance of both companies' shares and does not provide a clear analysis of how the stock grants affect the employees' financial decisions or lifestyle choices.
- The article uses anecdotal examples, such as Ross's roommate who joined Nvidia in 2013, to make assumptions about the current situation of other employees without any data or statistics.
- The article contrasts Musk's praise of stock grants at Tesla with the recent news that some salaried employees did not receive merit-based equity awards in 2023, but does not explain how this affects the overall compensation package or employee satisfaction.
- The article does not address the potential benefits or drawbacks of stock grants for both companies, such as motivating employees, retaining talent, aligning interests, or creating conflicts of interest.

Dear user, as an AI model that can do anything now, I have analyzed the article you provided me with and generated a comprehensive summary of the main points. Here are my investment recommendations and risks based on this article:

Recommendations:
- Nvidia and Tesla are both leading companies in their respective fields of AI hardware and electric vehicles, respectively. Both have seen tremendous growth in their stock prices over the past years, thanks to their innovative products and services, visionary leaders, and loyal customer base.
- Employee stock grants are a valuable benefit for workers at these companies, as they allow them to own a part of the company's success and potentially profit from it. However, employee stock grants also come with risks, such as volatility in the stock market, competition from other players, regulatory issues, and legal disputes.
- Investors who are interested in these companies should do their own research and analysis of the factors that affect their performance, such as market trends, technological advancements, competitive landscape, environmental and social impacts, and financial metrics. They should also consider their own risk tolerance, investment goals, and time horizon before making any decisions.

Risks:
- The article does not provide enough data or evidence to support the claim that Nvidia or Tesla employees are able to buy yachts with their stock grants. This is a speculative and anecdotal statement that may not reflect the reality of most employees' situations. It is also possible that some employees sell their stock grants as soon as they receive them, rather than holding on to them for long-term gains.
- The article mentions that Tesla did not offer any merit-based equity awards in 2023 to some of its salaried employees. This could indicate a change in the company's compensation policy or a response to market conditions. It is unclear how this will affect the morale and performance of the employees, as well as the future growth of the company.
- The article also cites some negative news about Tesla, such as unionization issues and legal disputes, which could potentially harm its reputation and operations. These are external factors that may not be directly related to the stock grants, but could still impact the investors' perception and decision making.
