As a government employee in India (CG), we are not allowed to choose aggressive investment strategy in NPS. Apart from that any change in the scheme requires us to choose only one Fund house which I do not know is reversible or not. Out of 3 default fund houses (SBI, UTI, LIC) only SBI has decent returns. There were ICICI and HDFC also as fund houses in NPS which have higher returns that SBI.
But, I have a concern that choosing only one fund house that too a pvt. fund house for a retirement investment looks like a bad idea. I don't know if I can change it back to default three government institutional fund houses.
How would I evaluate which fund house to choose? Even if I choose a pvt. fund house, am I losing anything in terms of diversification?
