Totally agree though PF names may differ from one individual to the other. Stick to bluechips. Dont think about the initial losses that you will incur during this rejig. Consider this as the tuition fee paid to Mr. Market.
Every senior member here would have had a phase where he would have paid this tuition fee.
These ~1% allocations in your PF are not going to help the overall returns of your PF in anyway. Hypothetically, even if Tata motors in your current PF were to double from 439 to 880, your overall PF returns will only increase by ~2%
Read a lot before you start with your PF building next time.
