The Business Brew is joined by Jen Ross this week. Jen was a professional short seller. Consequently, she has a unique perspective. It took Bill a while to understand the role of short selling in a portfolio but Jen’s comment about the need (or lack thereof) to hedge a quality equity portfolio really helped Bill understand what risks to think about hedging via short selling. Her Bio very unique: Jennifer L. Ross has more than 20 years of engineering and financial experience. She is a principal engineer in Launch and Enterprise Operations at The Aerospace Corporation. Prior to joining Aerospace, Ross held management and executive positions in the areas of material science and manufacturing, process engineering, and financial analysis. Her focus is analyzing the space industrial base and helping space startups conduct business with the U.S. Space Force. Ross transitioned from engineering to management consulting and finance in 2007. She spent five years as vice president of a public finance management and municipal bond firm. She later joined a hedge fund as an equity short seller/research analyst, analyzing corporate financials of publicly traded companies and predicting the probability of financial failure for those businesses. Ross joined Aerospace in 2015 when she saw the opportunity to combine her passions for both engineering and financial analysis.
