- The article does not provide any context or background information about Old Second Bancorp, its industry, competitors, market position, etc. This makes it difficult for the readers to understand why the upgrade is relevant and what are the potential benefits of investing in the stock.
- The article uses vague terms such as "attractive pick" and "upward trend in earnings estimates" without explaining how they are measured or what criteria are used to determine them. This creates confusion and uncertainty for the readers, who may not be familiar with the stock market jargon or metrics.
- The article relies heavily on Zacks Rank as a source of authority and credibility, but does not mention any other factors or analysis that support the upgrade decision. This suggests a lack of depth and independent thinking from the author, who seems to follow the herd rather than conducting his own research and due diligence.
- The article has a positive tone and expresses optimism about the stock's future performance, but does not provide any evidence or data to back up its claims. This may appeal to some emotional investors who are looking for quick gains, but it also increases the risk of misleading or overpromising the readers.
- The article is too short and lacks details, examples, or comparisons that could make it more informative and engaging for the readers. It seems like a hastily written piece that does not aim to educate or persuade the audience, but rather to attract clicks and ad revenue.
