They are putting their money into special things called options, which let them buy or sell Pfizer's stock at a certain price later on. The article tries to find out why these big people are so sure about Pfizer and what it means for other people who might want to invest in the company. Read from source...

- The title is misleading and sensationalist, as it implies that there is a deep dive into market sentiment, but the article does not provide any evidence or analysis of how the options trading reflects the overall market sentiment.
- The article uses vague terms like "unusual trades" and "bullish move", without defining what constitutes as unusual or bullish in this context. This makes it hard for readers to understand the basis of the claims and compare them with other sources of information.
- The article relies on secondary data from options history, which may not be representative of the current market conditions or the intentions of the traders. It also does not provide any context or explanation of how the options history relates to Pfizer's performance, outlook, or risks.
