This is a story about four companies that people can buy tiny parts of, called stocks. Some important people who work at these companies are buying more stocks because they think the companies will do well in the future. The article talks about Expensify and three other companies that cost less than $3 per share. Read from source...

1. The article is titled "Expensify And 3 Other Stocks Under $3 Insiders Are Buying". However, the article does not provide any evidence that these insiders are buying these stocks or why they would be interested in them. This is a misleading and clickbait title that fails to deliver on its promise.
2. The article mentions Expensify (NASDAQ:EXFY) as one of the four stocks under $3 that insiders are buying, but it does not provide any data or sources to support this claim. It also does not explain what Expensify is or how it operates. This is a poor and incomplete introduction to the company and its product.
3. The article provides some basic information about Perspective Therapeutics (AMEX:CATX), but it does not mention any of their recent developments, achievements, or challenges. It also fails to explain how the license agreement with Stony Brook University is relevant to the company's business model and growth prospects. This is a superficial and uninformative description of the company and its value proposition.
4. The article mentions Processa Pharmaceuticals, Inc., but it does not provide any details about their products, services, or pipeline. It also fails to mention how the recent public offering affects their financial situation and market outlook. This is another superficial and uninformative description of a company that leaves readers with more questions than answers.
5. The article uses vague and ambiguous terms such as "what's happening" and "what they do" without providing any context or clarification. These terms are too broad and general to convey any meaningful information about the companies and their activities. This is a poor and lazy writing style that does not engage readers or help them understand the topic better.
6. The article lacks any critical analysis, evaluation, or comparison of the stocks and their performance. It also does not provide any recommendations, suggestions, or insights for investors who are interested in these stocks. This is a shallow and unhelpful article that fails to deliver any value to its readers.
