<h1>Indian Markets Surge as GST Implementation Boosts Sensex by Over 300 Points; FMCG and Other Sectors Rally.</h1> Indian markets surged following the implementation of the Goods and Services Tax (GST), with the Sensex rising over 300 points, marking its largest single-day gain in a month. The GST reform, transforming India's indirect taxation into a unified system, boosted business sentiment and investor optimism, supported by positive global cues and capital inflows. The FMCG sector led the rally, with cigarette maker ITC seeing significant gains due to lower taxation under GST. Other sectors such as telecom, metal, realty, and auto also saw increases. The broader Nifty index also rose significantly, supported by domestic institutional investors' buying activities.
