Frequently asked questions about IDT activity
Which institutional owners are buying IDT?

What does "buy" mean in IDT activity?
"Buy" means an investor increased their reported position in IDT compared to the prior reporting period. This reflects growing exposure to IDT CORP-CLASS B (IDT) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
Is institutional interest in IDT increasing?
Institutional interest in IDT can be assessed by comparing the number of tracked funds adding or increasing positions versus those trimming or exiting across the periods shown. A higher number of additions typically signals increasing participation among large filers, but it should be read alongside position sizes and the full table.
