An index is a weighted basket. When KSE-100 is up, it means the basket as a whole is higher not that every member moved the same way.
A stock is one company. Company news, sector flows, and liquidity can push it against the index on any given day.
Practical habit: check the featured index for market mood, then open sectors or movers to see where leadership actually sits, then drill into a symbol page.
Peers on a stock page help you compare similar businesses in the same sector instead of judging a name in isolation.
