10b5-1 trading plan financial

"Reported sales were effected pursuant to a 10b5-1 trading plan."

A 10b5-1 trading plan is a pre-arranged strategy that allows company insiders to buy or sell company stock at set times, regardless of their current knowledge about the company's situation. It acts like a scheduled appointment for trading, helping prevent the appearance of impropriety or insider trading. This plan provides a way for insiders to sell or buy shares in a controlled, transparent manner, offering reassurance to investors about fair trading practices.

weighted average price financial

"The reported price in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

401(k) plan financial

"Common stock is held indirectly by a 401(k) plan for the reporting person."

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
