1. The introduction is too long and vague, it does not capture the reader's attention or provide any useful information about the stocks or their performance. It only mentions that U.S. stocks were in the red at the end of trading on Wednesday, which is old news by the time the article is published.
2. The paragraph structure is poor and confusing, it jumps from one stock to another without any clear transition or connection between them. It also mixes the information about each stock's price movement with the market summary, which makes it hard to follow and compare the stocks.
3. The use of percentages instead of actual prices or returns is misleading and unhelpful, especially for investors who are looking for more precise and relevant data. It also creates a sense of volatility and uncertainty that may not reflect the true situation of the stocks or their potential value.
