weighted average price financial

"The price reported 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.

Was the PTEN director’s sale made under a Rule 10b5-1 trading plan?

No. The filing’s Rule 10b5-1 checkbox is not marked, and the footnotes do not describe any Rule 10b5-1 trading plan, so no pre-arranged trading plan is reported for these transactions.

Does the Form 4 state how many PTEN shares the director owns after these sales?

No. For both reported transactions, the Form 4 leaves the shares beneficially owned following the transaction field blank, so it does not state the director’s remaining holdings after these sales.
