Since 2004, analyst Jason Perl has headed the Technical Strategy for Fixed Income, Currencies and Commodities division at UBS bank. He has made a name for himself applying the market-timing tools of vaunted analyst Tom DeMark, and his new book on the subject, DeMark Indicators (Bloomberg Market Essentials/Bloomberg Press), is due out in October.

Describing himself as "fairly contrarian by nature," Perl was drawn to DeMark’s work, which had just been introduced to the public through DeMark’s first book, The New Science of Technical Analysis (John Wiley & Sons, 1994).
