A group of big money people made some bets that they think American Express (a company that helps people pay for things) will not do well in the future.

- The article title is misleading and sensationalized, as it implies that only "market whales" are betting on AXP options, while in reality any trader can participate in this market segment.
- The article does not provide any clear definition or explanation of what constitutes an "unusual trade", nor how it is measured or detected by the author's methodology. This makes the data and conclusions unreliable and subjective.
- The article focuses on the percentage of bullish and bearish traders, but does not account for other factors that may influence their preferences, such as risk appetite, time horizon, market conditions, etc. It also does not compare these percentages to historical or benchmark data, which would provide more context and insight into the current sentiment trends.
- The article only reports the value of puts and calls, but not the volume or open interest, which are equally important indicators of liquidity and demand for AXP options. This creates an incomplete and distorted picture of the market dynamics and activity.

Bearish
Explanation: The article reports on large financial institutions making bearish bets on American Express options. It states that out of all the trades spotted, 6 were puts and 10 were calls, with most traders showing bearish tendencies (75%). This indicates a negative sentiment towards the stock price and expectations for the company's performance in the market.
