Mr. Boettrich is a Senior Consultant in NERA's Securities and Finance Practice. He specializes in securities class action cases alleging fraud and price manipulation. He has consulted on and managed cases involving Employment Retirement Income Security Act (ERISA) claims, alleged violations of Rule 10b-5, options backdating, Employee Stock Ownership Plan (ESOP) disputes, and public offerings.

Mr. Boettrich has analyzed the impact of alleged fraud on stock, bond, and options prices, assessed materiality, modeled inflation, and estimated aggregate damages in securities class action lawsuits. In addition, he has calculated damages to privately held securities subject to a private equity transaction. Mr. Boettrich has also assessed market efficiency and loss causation, and calculated loss avoided by insider trading.

His work frequently involves complex and big data sets, some of which require distributed computing technologies. He has developed algorithms to recognize patterns in data, to classify enterprise-level data, and to value complex derivatives.

Mr. Boettrich has extensively researched the dynamics of short selling and securities lending. His research includes the quantification and evaluation of short sale constraints, and the effects that such constraints have on the efficiency of market prices. He has applied this research to understand impediments to market efficiency in securities cases, and has published a white paper on the topic.

Mr. Boettrich holds a MSc degree from the Stockholm School of Economics, where he graduated first in his class. He also holds a BA degree in economics, with Distinction in Research, from the University of Rochester. He has completed all Core coursework toward his Doctoral degree in finance from the University of Rochester, where he was awarded a William E. Simon School Doctoral Fellowship.
