What does "buy" mean in MT activity?
"Buy" means an investor increased their reported position in MT compared to the prior reporting period. This reflects growing exposure to ARCELORMITTAL-NY REGISTERED (MT) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
