  This is the second part of the blog “A Layman’s guide to Investment” which I started last week. When we do investing, many of us hardly give any consideration how our asset allocation should change with changing time and this is not a wise approach. So, in this blog I am trying to set few simple guidelines which you may consider, 1.        Age 25-30:      Start investing at the earliest and increase your savings and investment as much as possible. This is usually the time when you have less family obligations and thus you can take maximum risks. Also, if you are salaried employee, try to increase your investment in Voluntary PF.   a.        Equity/MF Exposure:     50-60% b.        Fixed Assed Exposure:   20-30% c.        Other Assets:            ...

Consolidation of Public Sector Banks – Will it serve any purpose? Yes, definitely. The suggestion of consolidation among PSBs has quite old history. Narasimham Committee Report in 1991 (NC-I), recommended a three tier banking structure in India through establishment of three large banks with international presence, eight to ten national banks and a large number of regional and local banks. Narasimham Committee Report in 1998 (NC-II) also reiterated the recommendations on NC-I.   Few strong arguments for Consolidation can be given below: 1. Indian banking sector is highly fragmented . PSBs mostly competing with each other as they have same business model, products and segments. Herfindahl-Hirschmann Index (HHI)1 for Indian banking sector stands at 545.2, reflecting low levels of concentration. It will also enable geographical diversification, increase in market share and penetration to new markets, and help promote international acceptance and recognition.   ...

The enthusiasm for entrepreneurship is ever growing. However though it is debatable whether formal education really is a prerequisite to be an entrepreneur, we can at least say there is no harm if you start your entrepreneurial journey with some formal education about business.

TISS  2 Year MA in Social Entrepreneurship –  This is one of the most sought-after full time course on Soc...
