In the early 1980s, the firm existed simply to lure large Western companies with the promise of significantly cheaper IT work, but today Infosys has established a more robust economic moat with its 775 corporate customers. By focusing on expertise-driven businesses such as consulting, INFY has managed to justify higher-end pricing for its services -- and it's driving higher-end net profit margins in kind. >>5 Toxic Tech Stocks You Should Sell in March A skilled workforce of low-cost Indian programmers and consultants gives the firm pricing that competitors at home can't match, alongside expertise that's not easily recreated by other Indian firms.
