Rule 10b5-1 trading plan regulatory

"The sale transaction was effected pursuant to a Rule 10b5-1 trading plan"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average financial

"Represents the weighted average of multiple sale transactions"

A weighted average is a way of calculating an overall number when some items matter more than others by giving each item a different level of importance, or weight. Investors use weighted averages to combine figures like prices, returns or earnings so the result reflects the size or significance of each part — like grading a class where a final exam counts more than a quiz, producing a score that better represents true performance.
