- The title of the article is misleading and clickbait, as it implies that there are only three tech stocks that can save your portfolio, when in reality there may be more or less than three depending on the market conditions and individual preferences.
- The article does not provide any evidence or data to support its claims about the top three tech stocks being undervalued or having potential for growth. It simply cites the RSI as a momentum indicator, without explaining how it works or why it is relevant for this analysis.
- The article focuses on Calix's negative guidance and stock price drop, without mentioning any positive aspects of the company or its industry. This creates a biased and pessimistic tone that may discourage readers from investing in Calix or other tech stocks.
- The article does not provide any personal opinions or recommendations from the author or any experts, which would add credibility and value to the content. It only reports on factual information that can be easily found elsewhere.
