How to follow the player without moving camera?

I have 2d game:

• camera

• background

• holder->player

I need to scale only holder with pivot point from player's center. Player moves down. So the center of holder is always on player's position. Camera doesn't move.

 holder.localposition.y = -player.localposition.y;

I've tried different updates (FixedUpdate, LateUpdate) but in all cases it is jittering, the player or other objects on holder. Lerp doesn't help.
