Calix is a company that makes things to help other companies provide internet and phone services. They said they won't make as much money in the next three months as people thought, so their stock price went down. This made other big companies' stocks go down too because people were worried about how the economy is doing. Read from source...

Given the weak Q1 forecast and the stock's decline in pre-market trading, I would advise against buying Calix (CALX) at this time. The company is facing headwinds from lower demand for its networking solutions and increased competition from alternative providers. Additionally, the global economic uncertainty and rising interest rates may further dampen the outlook for tech stocks in general. Therefore, I would suggest looking for other opportunities with more favorable fundamentals and growth potential.

However, if you are a brave investor who is willing to take on higher risk and volatility, you could consider using Calix as a speculative play. This would involve setting a stop-loss order at a reasonable level and limiting your exposure to the stock. You could also monitor the news and earnings reports closely for any signs of improvement or reversal in the company's fortunes. In this case, you may benefit from the upside potential if Calix manages to beat expectations or surprise the market with positive developments.
