Markets are likely to extend gains in early trades Monday on the back of continued optimism in key global equities. After key benchmark indices scaled fresh peaks last week, investors are hoping that FIIs would continue to increase exposure to Indian markets, given the strong growth trajectory. India's record GST collections for the month of June further signifies the improving economic growth momentum. The street will react to June auto sales numbers, although weak exports remain a concern for most automakers. Investors will also be eyeing the FOMC Minutes from Fed’s June policy meeting slated to be released on Wednesday, and the US non-farm payrolls data for June to tricke in on Friday.
