About Bret Rosenthal

Bret Rosenthal is a well-respected capital management and algorithmic investing executive, and the principal at Rosenthal Capital Management LLC. His career began over 35 years ago with Lehman Brothers in New York City followed by Prudential Securities/Wachovia, all under the watchful eye of his father, Gary Rosenthal, with whom he still works today. The Rosenthal Group managed one of the most successful private client businesses in the country at all three firms, the history of which was chronicled in R.J. Shook’s book The Winner’s Circle. Bret’s stock trading approach was highlighted in Steve Cawiezell’s book, Expert Trading Systems: Successful Traders Share Their Secrets. Bret began building stock trading systems in the late 1990’s. In 2001, he implemented his first successful algorithmic system throughout the Rosenthal Group’s client structure: P.A.C.E. (Proprietary Analyses and Computer Enhancement). While the intervening years have seen the acronym change and the employed tools enhanced, the core of that system lives on in the strategies and systems at Rosenthal Capital Management.
