In an interview with ET Now , President & CEO,, says it might have taken long to get a $100-billion market cap, but you will start seeing many more coming over the next five to seven years.Edited excerpts:In my opinion, valuations will always move in a narrow range depending on the economic cycle. The most important thing to watch out for is how the economy is growing and how these companies are taking part in that.What we have to look for in HDFC Bank or HDFC, is whether the corporate earnings have multiplied many folds over the years. As we move from $2.5-trillion GDP over next seven-eight years, the corporate earnings will also multiply. The companies will keep on growing 15% to 20% or more. In that sense, the $100 billion mark is just a milestone. It is not the end game. We will have at least 10-15 more companies in next seven-eight years that will cross this mark.If our GDP is going to be $5 trillion, if the market cap is anywhere between $4-6 trillion, you will have to have larger corporations. The key thing is not to really worry about the valuation re-rating. That will always be a narrow range but key thing is what kind of quantum jump can happen on the earnings of the corporations and to identify those kind of sectors, segments and corporations that could benefit from this economic recovery and be part of the big club.Rs 100-crore movies took a long time to come about but once the first Rs 100-crore movie came out, in the next five-seven years, you had at least 10-15 Rs 100-crore movies. This happens to even markets and economies and all those things. So, it might have taken so long to get a $100 million market cap once, but you will start seeing many more coming over the next five to seven years.But coming back to the point you mentioned, ultimately you can all discuss intellectually but you have to really take action. As for where to make money, I believe that India is in a very great spot over the next seven, eight years and to benefit out of this, you have to buy and take your exposure to the stocks which are aligned or sectors which are aligned to the economic recovery or economic growth of the country. Banking and financial services is one of the biggest part of that and will always be there and will be a big value or wealth creator.I believe institutions like HDFC Bank can become much bigger than what they are today. It is just that at times it becomes very difficult to predict how it will happen. A lot of people used to say the same thing for IT companies. I do not think anybody gave any chance for TCS to become $100-billion market companyany time and people thought that it is a matured business, it will not grow. But it has happened and it has found a new kind of growth engine. You will find things changing.Definitely, domestic consumption is a very big theme and it is going to last for long, long period of time. I would strongly believe that there are opportunities to create big wealth over the next five, ten years.Lastly, there are the segments where you have to take a little bit of risk and a little bit of contrarian approach. Those segments where there are huge manufacturing capacities underutilised, tend to give you multi baggers in a shorter period of time as and when the cycle turns right but you have got to get those cycles right, you have got to get those hypothesis right and once that happens you get many more opportunities.I would say that play on India economic recovery, economic growth and there are many ways of playing through. In mutual funds, you can play through baskets or through stocks.Reliance is around the corner. So, definitely Reliance, HDFC Bank. I would say HDFC Bank is going to be the next one to join $100-billion market cap club.I wish I could answer your questions but there are lots of them I can tell you. We will have at least 100 plus $10 billion company soon.
