Owning A Significant Percentage of a Public Company's Stock, What are the Thresholds?

  This is a bit of a high class problem, but if you have at least $10-50 million and are buying publicly traded equities, there are some things to consider when allocating your wealth.

The key percentages for owning a given amount of stock in a public company can vary depending on several factors, including the size of the company, the number of outstanding shares, and the ownership structure. However, some general guidelines include:

  • Less than 1%: This is considered a small position and is unlikely to have a significant impact on the company's overall ownership structure or decision-making.
  • 1-4.99%: This is still a relatively small position, but it may be enough to give an individual a voice in company affairs and the ability to influence shareholder votes.
  • 5-10%: This is a significant ownership stake that can provide an individual with a seat on the board of directors or other influential positions. 13D filing required if public.
  • 10-20%: This is a large ownership stake that can give an individual significant influence over the company's decision-making and overall direction.
  • 50% or more: This is a controlling interest and gives an individual the ability to make significant decisions and influence the company's operations.
These percentages are just guidelines, and the actual impact of an individual's ownership stake can vary depending on the company's specific circumstances and ownership structure. Moreover, it's always important to consider the potential risks and benefits of owning a particular stock and determine the appropriate percentage based on individual circumstances and investment goals.

Significance of Owning 5% or More of a Public Company (Schedule 13D Filing)

If an individual or entity owns 5% or more of a public company's stock, they are required to disclose their ownership position to the Securities and Exchange Commission (SEC) in the United States. This is known as a Schedule 13D filing.

The Schedule 13D filing must include the following information:
  • The name and address of the individual or entity that owns the shares.
  • The number and class of shares owned.
  • The purpose of the ownership, including any plans or proposals for changing the company's management or strategy.
  • The source of funds used to purchase the shares.
  • Any contracts, arrangements, or understandings with other shareholders or third parties related to the ownership of the shares.
  • Any related hedging or other transactions related to the shares.
The Schedule 13D filing must be made within ten days of the individual or entity acquiring 5% or more of the company's stock. In addition, any changes to the ownership position or purpose of ownership must be disclosed in subsequent filings.

It's important to note that the disclosure requirements for owning 5% or more of a public company's stock may vary by jurisdiction, so it's important to consult with legal and regulatory experts to ensure compliance with all applicable regulations.

General Theory's of Portfolio Allocation

There is no one-size-fits-all answer to the ideal percentage of a stock's total market cap to own, as it depends on various factors such as an individual's financial goals, risk tolerance, and overall investment portfolio. However, some experts recommend not holding more than 10% of one's portfolio in a single stock to avoid overexposure to its risks. Warren Buffet may disagree here (look at his Apple holdings).

Owning too much of a single stock can have significant implications on an individual's portfolio. If the stock performs well, it can result in substantial gains, but if it underperforms, it can lead to significant losses. Moreover, it can also result in an unbalanced portfolio, which can negatively impact diversification.

Additionally, owning a large percentage of a single stock can also expose an individual to company-specific risks such as management changes, legal issues, or industry disruption. Diversifying across different sectors and asset classes can help mitigate these risks.

Overall, it is essential to consider the potential risks and benefits of owning a particular stock and determine the appropriate percentage based on individual circumstances and investment goals.
