Some wealthy people or institutions have bought or sold a lot of options for Moderna, a company that makes a COVID-19 vaccine. This could mean they know something about the company that others don't. They have different opinions on whether the stock price will go up or down. The article is telling us to keep an eye on this company because something might happen soon. Read from source...

- The headline is misleading: It implies that "whales" (large investors) are selling MRNA, but the article is about options trading, not direct stock sales.
- The article is poorly written, with grammatical errors, run-on sentences, and confusing structure.
- The article lacks critical analysis and context: It doesn't explain what options are, how they work, or why they are important to monitor. It also doesn't provide any evidence or data to support the claim that these large investors are "selling" MRNA.
- The article uses emotional language and biased terms: It refers to Moderna as a "commercial-stage biotech" rather than a leading COVID-19 vaccine developer, and it implies that the options trades are a negative sign for the stock without providing any reasoning or justification.
- The article is outdated: It uses data from December 2020 for Moderna's IPO and mid-2023 for its clinical trials, while the current date is May 2023.

Overall, the article is poorly researched, written, and argued, and it does not provide any useful or accurate information for readers.
