Petroleum products and chemicals are a major contributor to India's industrial GDP, and together they contribute over 34% of its export earnings. India hosts many oil refinery and petrochemical operations, including the world's largest refinery complex in Jamnagar that processes 1.24 million barrels of crude per day.[171] By volume, the Indian chemical industry was the third-largest producer in Asia, and contributed 5% of the country's GDP. India is one of the five-largest producers of agrochemicals, polymers and plastics, dyes and various organic and inorganic chemicals.[172] Despite being a large producer and exporter, India is a net importer of chemicals due to domestic demands.[173]

The acceleration continued through 2014–15 and 2015–16 with growth rates of 7.5% and 8.0% respectively. For the first time since 1990, India grew faster than China which registered 6.9% growth in 2015.[needs update] However the growth rate subsequently decelerated, to 7.1% and 6.6% in 2016–17 and 2017–18 respectively,[144] partly because of the disruptive effects of 2016 Indian banknote demonetisation and the Goods and Services Tax (India).[145] As of October 2018, India is the world's fastest growing economy, and is expected to maintain that status for at least three more years.[146]
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
