Zoom conference call with ARK's Cathie Wood

ARK founder Wood explains her advocacy of Tesla, Bitcoin and genomic medicine. Her process entails identifying a company's fundamental competitive advantage -- for example, Tesla is an artificial intelligence company, not an auto company. This is a "deep value" investment style because it seeks situations in which she can project revenues and profits -- based on both rising market share and falling costs of goods sold --  that the market underestimates.
