About the Author
After serving as Assistant Director of the NYSE Floor Department, Justin Mamis founded and edited The Professional Tape Reader in 1972, selling it in 1977 to its current editor with thoughts of retirement. Instead he spent several years as an "upstairs" Member-Trader for Phelan, Silver, an NYSE specialist firm and subsequently settled into his roles as market advisory letter writer, forecaster, and philosopher on behalf of Wertheim & Co., and then Gordon Capital. He then became Senior Vice President and Chief Market Technician at Hancock, where he wrote his weekly Mamis Letter. Quotes from the Mamis Letter appear frequently in Barron's and The Wall Street Journal and his often heretical and usually grumpy comments can be heard from time to time on CNBC. Among his credentials he has been voted for several consecutive years to the Institutional Investor "All-Star Team" in the categories of Market Timing and Market Technician. Justin continues to write his market letter and do forecasting and philosophizing.
