Despite positive global cues and healthy domestic macro-economic data, the local equity benchmark -- Nifty -- gave up its initial gains to end flat on Tuesday with positive bias. Indias core sector growth accelerated to 5% in March 2017, on the back of a sustained growth in the steel and coal output, supported by a stable rise in natural gas production. Besides, Indias manufacturing sector growth improved for the fourth consecutive month in April. The seasonally adjusted Nikkei India Manufacturing Purchasing Managers Index (PMI)-a composite single-figure indicator of manufacturing performance- remained at 52.5 in April to match Marchs reading. Investors remained cautious ahead of the two-day US Federal Open Market Committee meet scheduled to start later in the evening. Some concerns also came with the FICCIs survey report that the protectionist trends gaining strength in the developed world could have an adverse impact on Indias export performance. However, Prime Minister Narendra Modi`s assertion that India was never a more promising investment destination than it is today, helped the index to end slightly positive. He further said that today, Indian economy is the fastest growing major economy in the world. In addition to maintaining this pace, our focus is to remove the inefficiencies from the system.
