$Novo Nordisk AS(NVO.US) has a high cost-performance ratio for building a position at this level. As long as NVO does not go bankrupt, its strategy of capturing the market with low prices can secure its future cash flow income. Building a position here is equivalent to holding a call option with no expiration date, as all negative factors have already been priced in. Any improvement in fundamentals in the future could lead to a potential surge in the stock price. A safer approach is to reduce the cost to around 33 through day trading, ensuring an invincible position.
