In the book Coffee Can Investing, authors Saurabh Mukherjea, Rakshit Ranjan, and Pranab Uniyal advocate for a low-risk, long-term approach to building wealth in the Indian market. The text illustrates common financial pitfalls, such as frequent trading, high brokerage fees, and over-reliance on real estate, through the cautionary stories of individual investors. To counter these mistakes, the authors propose the Coffee Can Portfolio, which involves selecting high-quality companies with consistent revenue growth and high returns on capital and holding them untouched for a decade. By prioritizing patience and fundamental business strength over market timing, investors can minimize the negative impact of inflation and taxes. Ultimately, the source provides a comprehensive framework for financial planning, emphasizing the use of low-cost instruments like direct mutual funds and exchange-traded funds to achieve specific life goals.
