You can go with either a PMS or a Registered Equity Investment Advisor. Investing in a quality portfolio will definitely generate wealth for you. What matters is the investment philosophy of the advisor or fund manager.
Go for someone with a proven track record – check their past 1 yr, 3 yr and 5 yr returns comparing with the Total Returns index (nifty 50 or nifty 500).
Go for a model which gives you transparency, flexibility, easy withdrawal and predictability of fees. And of course check their client testimonials and feedback.
