From 2000 to 2010, the country attracted $178 billion as FDI.[307] The inordinately high investment from Mauritius is due to routing of international funds through the country given significant tax advantages – double taxation is avoided due to a tax treaty between India and Mauritius, and Mauritius is a capital gains tax haven, effectively creating a zero-taxation FDI channel.[308] FDI accounted for 2.1% of India's GDP in 2015.[11]

Textile industry contributes about 4 per cent to the country's GDP, 14 per cent of the industrial production, and 17 per cent to export earnings.[189] India's textile industry has transformed in recent years from a declining sector to a rapidly developing one. After freeing the industry in 2004–2005 from a number of limitations, primarily financial, the government permitted massive investment inflows, both domestic and foreign. From 2004 to 2008, total investment into the textile sector increased by 27 billion dollars. Ludhiana produces 90% of woollens in India and is known as the Manchester of India. Tirupur has gained universal recognition as the leading source of hosiery, knitted garments, casual wear and sportswear. Expanding textile centres such as Ichalkaranji enjoy one of the highest per-capita incomes in the country.[190] India's cotton farms, fibre and textile industry provides employment to 45 million people in India,[189] including some child labour (1%). The sector is estimated to employ around 400,000 children under the age of 18.[191]
I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.
From the beginning of the 19th century, the British East India Company's gradual expansion and consolidation of power brought a major change in taxation and agricultural policies, which tended to promote commercialisation of agriculture with a focus on trade, resulting in decreased production of food crops, mass impoverishment and destitution of farmers, and in the short term, led to numerous famines.[93] The economic policies of the British Raj caused a severe decline in the handicrafts and handloom sectors, due to reduced demand and dipping employment.[94] After the removal of international restrictions by the Charter of 1813, Indian trade expanded substantially with steady growth.[95] The result was a significant transfer of capital from India to England, which, due to the colonial policies of the British, led to a massive drain of revenue rather than any systematic effort at modernisation of the domestic economy.[96]
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.
