Number of trades Vs quantity

Increasing number of trades (qty 10 and stocks 10) or increasing quantity in less trade (qty 50 and stocks 2)

Which is profitable?

Looking for cumulative P & L.

charges wise if you will be executing only 2 trades instead of 2 then surely 50 quantity with 2 stocks will be better idea… also you will have to manage and look after loss stocks… but if you go with 10 quantity and 10 will be much better as you risk will be diversified so this might boost your returns and different stocks will have different movement and all…

Thank you
