The book's title, "100 to 1," refers to the idea that a stock can increase in value by 100 times (or 10,000%) its original price, which is a rare but not impossible occurrence in the stock market. Phelps argues that with the right investment approach, it is possible to achieve such remarkable returns.

"100 to 1 in the Stock Market" is a book written by Thomas J. Phelps, a well-known American investor and stock market expert. The book, first published in 1996, focuses on stock market investing and provides insights into Phelps' investment strategies.
