Michael Murphy CFA

Founder & Editor  ·  California Technology Stock Letter

Michael Murphy CFA has been identifying technology investment opportunities for individual investors since founding the California Technology Stock Letter in 1982. For more than four decades, he has guided subscribers through every major technology cycle — from the dawn of the personal computer to the current artificial intelligence, gene editing, and autonomous vehicle revolutions.

Murphy’s approach combines the rigorous analytical framework of institutional Wall Street research with a deep, firsthand knowledge of Silicon Valley’s technology ecosystem. His initiating coverage memos — modeled on the buy-side research that professional portfolio managers rely on — bring institutional-grade analysis to individual investors for the first time.

As a Chartered Financial Analyst, Murphy applies a disciplined valuation methodology to speculative technology stocks: always presenting both the bull and bear case, always disclosing the risks alongside the opportunity, and always sizing the recommendation to the capital a prudent speculative investor should commit.
