1. PubMatic (PUBM) - The stock is falling due to worse-than-expected second-quarter revenue results. Despite beating the analyst consensus estimate for earnings, the company's sales missed estimates. This indicates a possible slowdown in revenue growth, making the stock less attractive for investment.

2. Eventbrite (EB) - This stock is declining due to the company's worse-than-expected second-quarter revenue results and a lower-than-expected FY24 revenue guidance. These factors suggest that Eventbrite may face challenges in generating revenue in the coming quarters, making it less appealing for investment purposes.

3. Five9 (FIVN) - The stock is experiencing a dip after the company posted its second-quarter results. This indicates that investors may be cautious about investing in Five9 until there is more clarity on the company's future growth prospects.

4. Array Technologies (ARRY) - The stock is falling after the company cut its FY24 guidance. This suggests that the company's projected revenue growth may be lower than previously anticipated, making it a less attractive investment option.

5. Lumen Technologies (LUMN) - The stock is falling after dipping around 19% on Thursday. It may be experiencing selling pressure due to concerns over its future growth prospects or other company-specific factors. However, without more information, it's difficult to pinpoint the exact reasons for the stock's decline.

These stocks are experiencing a decline in their share prices, which may indicate potential risks for investors. It's essential to conduct thorough research and consider various factors, including the company's financial health, market trends, and economic conditions, before making any investment decisions.
