A person who works at Retractable Technologies bought some more shares of their own company with their money, because they think the company will do well in the future. The same thing happened with three other companies that have low prices and people think they are good buys. Read from source...

1. The article title is misleading as it implies that insiders are buying four stocks, but only three are mentioned. This creates confusion and distracts the reader from the main content of the article. A better title would be "Retractable Technologies And 2 Other Stocks Under $3 Insiders Are Buying".
2. The article does not provide any context or background information about the companies or the insiders who are buying their shares. This makes it difficult for the reader to understand why these stocks are worth investing in and what factors might influence their performance. A brief introduction that explains the industry, market trends, and the insider's role would be helpful.
3. The article focuses on the recent insider buying activities without considering other relevant data such as financial results, growth prospects, or analyst ratings. This gives a biased and incomplete picture of the stocks and their potential value. A more balanced approach that also considers these factors would be more informative and objective.
4. The article uses emotional language such as "insiders are buying" without providing any evidence or analysis to support this claim. This implies that insider buying is a positive signal for the stocks, but it does not prove that insiders have better information or expectations than the market. A more rational argument would be based on facts and statistics that show the relationship between insider buying and future performance.
5. The article ends with an unrelated promotion for Benzinga's other services such as research, pro, data & APIs, and broker reviews. This is irrelevant to the main topic of the article and might be seen as a spammy or manipulative tactic to attract more customers. A better conclusion would be a summary of the key points and a disclaimer that investors should do their own due diligence before making any decisions.
