Differentiated Product
Ann is one of the most tenured analysts on Wall Street, covering the Healthcare Services sector as an associate or Senior Analyst for over 29 years. Ann is known for her high-quality research and ability to get high-quality corporate access with C-suite management. On the research side, she covers seven sub-sectors within healthcare services (managed care, hospitals, retail pharmacy, clinical labs, CROs, behavioral health and post-acute facilities), highly specialized in each one. Each sub-sector has its own industry-specific dynamics that drive underlying trends and stock movements, as well as major macro drivers (e.g. political/Washington) that she must stay abreast of to make the best investment recommendations for her clients. Ann writes a weekly research note called Hynes Healthcare Insights, a monthly note on the funding environment for the CRO industry and a proprietary quarterly physician survey to help clients stay abreast with the constantly shifting healthcare services universe.
