Tim Lincoln

Co-Founder and Managing Director

Tim is one of Australia’s most experienced financial professionals, helping to empower self-directed investors for over three decades.
Tim co-founded Lincoln Indicators in 1991, teaming up with his father Dr. Merv Lincoln to computerise and commercialise Dr. Lincoln’s PhD thesis, ‘The Usefulness of Accounting Ratios to Describe Levels of Insolvency Risk’. Their vision was to create software solutions that via the analysis of financial accounts, would calculate the Financial Health of stock exchange listed companies.
In 1997, after six years of testing and development, Stock Doctor was launched and has since grown to become Australia’s premier DIY sharemarket investment platform. Utilising unique, proprietary algorithms and exclusive quantitative data driven research methodology, Stock Doctor gives much-needed support and guidance to DIY and SMSF investors to confidently invest in financially healthy, high-quality companies and identify those at risk of potential corporate failure.
Building on Lincoln Indicators’ mission to ‘empower global sharemarket investors to invest successfully with confidence, control and peace of mind’, in 2003, Tim launched Lincoln Managed Funds. This suite of Australian and US investment funds caters for time poor investors who trust the Lincoln Indicators quantitative methodology but prefer to leave the management of their portfolios to the experienced Lincoln Indicators team.
Tim is recognised globally as one of Australia’s most experienced financial professionals. He was invited to participate in the Global Access Program at the University of California in Los Angeles (UCLA), to help guide businesses with global potential. Tim was also selected to participate in exclusive entrepreneurial programs at Berkeley University, California.
Today, Tim has grown a highly successful financial technology and investment business that includes a growing team of 40 finance professional, thousands of long-term Stock Doctor members and over $800 million invested in their three industry leading Australian and US managed funds.
In 2021, Tim was appointed as a Director of the Carlton Football Club. Tim joins the Carlton board to collaboratively guide the Club to create competitive advantages by applying his data analysis expertise to significantly enhance decision making processes and improve the probability of successful outcomes, provide meaningful insights and introduce strong accountability metrics.
