According to Rule 144, what is the maximum number of shares Mr. Brown could sell given the trading volume history provided?

To determine the maximum number of shares Mr. Brown could sell under Rule 144, it's essential to understand the conditions set by this regulation regarding the sale of restricted and control securities. Rule 144 primarily limits the amount of securities that an affiliate can sell within a specific timeframe, typically based on the trading volume of the security.

One key component of Rule 144 is the volume limitation, which generally allows for the sale of either 1% of the outstanding shares of a company or the average weekly trading volume of the shares in the last four weeks, whichever is greater.

Given the trading volume history provided, if the data indicates an average weekly volume that leads to a calculated maximum of 18,400 shares, this figure aligns with the stipulations of the rule and reflects Mr. Brown's ability to sell without imposing undue pressure on the market. Such detailed adherence to the specific volume constraints ensures that the sale remains compliant with securities regulations, fostering a fair trading environment.

Thus, selecting 18,400 as the maximum number of shares Mr. Brown could sell is appropriate, highlighting the importance of volume calculations in Rule 144 compliance.
