Okay, I read an article about big investors buying options on a company called Alcoa. Options are like bets on how much a stock will go up or down in price. The big investors, called whales, have been looking at prices between $29 and $50 for Alcoa's stock. They watch the volume and open interest to see how many people are buying and selling options, which helps them decide when to make their bets. Read from source...

- The article lacks a clear thesis statement that guides the reader through the main points and arguments. It seems to be more of a summary than an analysis or opinion piece.
- The article does not provide any evidence or data to support its claims about market whales and their recent bets on Alcoa options. Where are the charts, graphs, statistics, or expert opinions that back up the assertions?
- The article uses vague and ambiguous terms like "whales" and "significant trades" without defining them or explaining how they are measured or identified. What is the criteria for considering a trade as whale-like or significant? How does this affect the average retail investor?
- The article focuses too much on the volume and open interest of Alcoa options, but does not explain why these metrics matter or how they influence the price movements. It also does not compare them to other similar companies or industries for context.
- The article ends abruptly with a description of Alcoa's business activities, without any conclusion or recommendation for further action. What is the purpose of this paragraph? How does it relate to the rest of the article?
