A big company called Amazon is going to join a group of other important companies in the Dow Jones Industrial Average (DJIA). But some people think this might not be very good for Amazon, because other similar companies didn't do much better after joining the group. They just stayed the same or went up a little bit slowly. So it's like joining a special club, but you don't know if it will help you or not. Read from source...

1. The author of the article seems to have a negative bias towards Amazon, as he compares their inclusion in the Dow Jones Industrial Average (DJIA) with other companies that did not perform well after joining the index. This is an unfair comparison, as each company has its own unique circumstances and challenges.
2. The author also makes an argument based on history repeating itself, but he does not provide any solid evidence or data to support this claim. History can never repeat itself exactly, and there are always factors that can change the outcome of events. It is irrational to assume that the same pattern will happen again with Amazon and Walgreens.
3. The author uses emotional language such as "dead money" and "not a great thing", which implies that he has a negative emotional reaction to Amazon's inclusion in the DJIA. This could cloud his judgment and make him more likely to see negative aspects of the situation, while ignoring any positive ones.
4. The author also does not consider other possible factors that might affect Amazon's performance after joining the DJIA, such as changes in consumer behavior, technological advancements, competitors, or market conditions. These factors could have a significant impact on how well Amazon performs, and it is unreasonable to assume that their inclusion in the index will be the only determining factor.
