In the early 18th century, the Mughal Empire declined, as it lost western, central and parts of south and north India to the Maratha Empire, which integrated and continued to administer those regions. The decline of the Mughal Empire led to decreased agricultural productivity, which in turn negatively affected the textile industry. The subcontinent's dominant economic power in the post-Mughal era was the Bengal Subah in the east., which continued to maintain thriving textile industries and relatively high real wages. However, the former was devastated by the Maratha invasions of Bengal and then British colonization in the mid-18th century. After the loss at the Third Battle of Panipat, the Maratha Empire disintegrated into several confederate states, and the resulting political instability and armed conflict severely affected economic life in several parts of the country – although this was mitigated by localised prosperity in the new provincial kingdoms. By the late eighteenth century, the British East India Company had entered the Indian political theatre and established its dominance over other European powers. This marked a determinative shift in India's trade, and a less-powerful impact on the rest of the economy.
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.
