About Pacific Square

Pacific Square Research is an independent subscription-based research firm that combines fundamental, investigative and forensic analysis. Our target subscriber base includes institutional investors as well as auditing and insurance firms. We believe our performance, since inception, has established us to be a credible source of actionable ideas.

We are unique among research firms because of our complementary skills, experience and collective instincts. We (just the two of us) personally conduct all of the research, analysis and writing, and we can honestly say: We have been doing this long enough to know it when we see it! 

We combine our talents to identify business models and financial statements that we believe are flawed, stretched or misrepresented, and to a lesser extent those that are under-appreciated, overlooked or washed out.

Our reports are prepared for informational purposes only. We are not an investment adviser and do not provide investment advice to the subscribers or readers of our reports.
