I think a better example is IBVENTURES, SORILINFRA type stocks and the usual BSE stocks which move without reason
Graphite electrode companies had a reason to move which was macro reason and a genuine news which everyone knows
So even if they move in circuits, it was I guess because their valuation increased so fast due to China closing down GE production, that moving normally was not an option, so it just moved in circuits.
But problem with GE companies is once there is bad news like China reopened production, the operators will know much before, and it will go down like falling cards.
