It’s been a wild week of investing in GameStop, AMC, and other companies, with amateur investors driving up prices. Investment app Robinhood decided to halt trading and was highly criticized. Robinhood was accused of not having enough liquidity to cover trades, succumbing to pressure from hedge funds, and trying to protect investors, yet interfering with their trading decisions and opportunities to gain high returns.

In a CNBC interview with Andrew Ross Sorkin, CEO Vlad Tenev defends the company’s decision to block trading. He denies the accusations but does mention the liquidity and responsibility. How clear is his explanation?

His video is a good one to analyze for his delivery skills and appearance. His skin and wall colors are rather pink, and although he sounds confident, he could move his upper body more to seem relaxed. Fillers signal a conversational style, which is appropriate here, but he overuses “um,” and I find it distracting.
