Besides analyzing stock markets, the book considers a wide
range of speculative markets for various items such as real
estate, commodities , postage-stamps, antiquarian books.
In particular, it highlights the following regularities:(i) During
a speculative episode, the price of expensive items increases
more than the price of less expensive items. This is referred
to as price multiplier effect.(ii) Price peaks for stocks and
most commodities on average follow a well-defined pattern
that we call the sharp peak - flat through pattern; in
contrast real estate price peaks follow a flat peak
pattern.(iii) The stocks whose prices experience the
strongest increase during a bull market, better resist during
the subsequent bear market, an effect referred to as the
resilience pattern. Such regularities pave the way for a
mathematical theory of speculation. Being mainly empirical,
the book is easy to read and does not require technical
prerequisites in finance, economics or mathematics.
