Good to see that you decided to start slow, maybe a learning from last time. Would suggest you keeping in that way and keep adding in small lots.
I do hold Aurobindo and am positive on it, best in the pharma at the present stage. Cochin Shipyard is a decent play since its one of the few profit making company in its herd.
Hold Infy as well but I am not expecting much from it in the next 1-2 years, more of a defensive play for me. Would suggest adding HCL as well.
Your portfolio lacks exposure to Financial side (RBL Bank, DCB, Reliance Cap, Edelweisse, Dewan Housing etc) and Infrastructure-Defence Sector plays (Reliance Infra, L&T, HCC, Suzlon, Jkumar Infra, Va Tech Wabag, etc) which is very essential if you believe India will be in a better place 5-10 years down the line.
I normally try to average on the way down and hold for 3-5 years at the minimum.
Also would suggest reading "One up on Wall Street" if you haven't already. Great Book.
