📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added ALGN than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
