John Bollinger is an American author, financial analyst, technical research contributor, and the creator of Bollinger Bands.
Bollinger Bands are a technical trading tool designed to answer the question “Are prices high or low on a relative basis? created by John Bollinger in the early 1980s. They arose from the need for adaptive trading bands and the observation that volatility was dynamic, not static as was widely believed at the time. Bollinger Bands can be applied in all the financial markets including equities, forex, commodities, and futures and used in most time frames, from very short-term periods, to hourly, daily, weekly or monthly.
John’s book, Bollinger on Bollinger Bands (2001), has been translated into eleven languages. He has published the Capital Growth Letter since 1987, a newsletter which provides technical analysis of the financial markets. As President and Founder of Bollinger Capital Management, John Bollinger offers technically focused money management services to individuals, companies, trusts, and retirement plans.
