Some people who work at or have important positions in some companies are selling their shares of those companies. This could mean they think the company is not doing well, the stock price is too high, or they just need money. When these insiders sell their shares, it might make other investors worry and also sell their shares. The article talks about 4 companies where this happened: NetApp, Zoom Video, Arrowhead Pharma, and Affirm Holdings. Read from source...

- The article does not provide any clear reasons or evidence for why insiders are selling shares of NetApp, Zoom Video, Arrowhead Pharma and Affirm Holdings. It merely states that they are selling without examining the possible motives, such as diversifying their portfolio, tax implications, personal issues, etc.
- The article uses vague and subjective terms like "could indicate", "may suggest", "could be a sign of" to imply causality or correlation between insider sales and negative outlooks for the companies. This is misleading and irresponsible journalism that could influence investors' decisions based on speculation rather than facts.
- The article does not disclose any potential conflicts of interest, such as receiving compensation from other sources, having personal or professional ties to the companies mentioned, etc. This creates a conflict of interest and undermines the credibility of the author and the publication.
