i bought parsvanth at 420 and canara bank at 320 but suddenly market went down . can these shares again go up and give me good profits

unless you require money do not sell these stocks. although they r down at this time, both the sectors construction n banking r going to give investors long term benefits.i have done some research on parsvanath n its a good mgmt n story. dont have any idea abt canara bank but banking sector on a whole is good.
