The selected window contains 2 eligible Form 4 transactions for MLM, but none are open-market code P purchases or code S sales. Awards, option exercises and tax-related dispositions remain visible in the filing history, but they are not used to manufacture a directional sentiment signal.
A longer signal window may reveal earlier directional activity. The filing table below intentionally remains independent of this selector so the underlying SEC history is still available for inspection. Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
