The most recent book written by well-known research analyst Mahesh Chandra Kaushik is this one. With the rise of discount brokerage houses and the growing number of retail investors participating in options and market delivery, the old methods of investing in stocks have become nearly useless. Gone are the days when investors would purchase large quantities of a stock and hold it for a 15–20 percent return.Currently, the majority of retail investors trade intraday, profit on a single day, or profit from a call option with a seven-day short expiry in an option. They also occasionally take a tiny profit in a swing trade, which causes more small range market movements.
