The company "Larsen & Toubro Limited" is in technology, engineering, construction and manufacturing company. This well know name in infrastructure in a world class company. It not only depends on India but takes world wide contracts. Seeing many infrastructure company available at high valuation based on expectation, I suggest to hold this stock for very long term to get maximum out of it. I think, no way it can give you less than 20% every year.
Though it is also available at high valuation now but seeing its size and quality you can take it as safe bet for investment.
