1. Inconsistent Behavior - The article mentions that Deutsche Bank analyst Matt O’Connor upgraded the rating for Bank of America Corporation BAC from Hold to Buy and announced a price target of $45. But in reality, the article neglects to mention that the stock's current price is $40.75, making the price target incorrect.

2. Biased Argument - The article appears to have a bullish slant, selectively choosing to highlight upgrades and not mentioning downgrades. This could lead readers to believe the market is only moving upwards, which may not be the case.

3. Irrational Argument - The article states that "Top Wall Street analysts changed their outlook on these top names." Yet it provides no context or explanation as to why these changes occurred. The reader is left with no understanding of the factors that may have influenced these decisions.

4. Emotional Behavior - The language used in the article is somewhat dramatic, using phrases like "Top Wall Street analysts turned bullish" and "Upgrades announced." This type of language can evoke an emotional response from the reader, potentially leading to impulsive investment decisions.

In conclusion, the article could benefit from improved consistency, balanced arguments, rational explanations, and a more detached writing style to avoid evoking unnecessary emotional reactions.
