Good time for a STP to a new portfolio of mutual funds

Hi there,

I have a 4 year old, highly unbalanced and un-diversified portfolio containing only focused MFs, which i will be converting into a more balanced one. Given the current market indices touching highs, is it recommended that i do an STP (Systematic Transfer Plan) and change my portfolio or just redeem my MFs and wait for the market to go down, to get better NAV value.
