This article talks about three stocks that might not do well soon because they are moving too much and too fast. People who buy and sell things quickly look at these numbers to decide if a stock is worth it or not.

1. The article title is misleading and clickbait, as it implies that the three tech and telecom stocks mentioned are definitely going to lose value and harm investors' portfolios, when in fact they could still perform well or recover depending on various factors and events. A more accurate title would be "Three Tech And Telecom Stocks That Are Facing Challenges Or Uncertainty".
2. The article does not provide any evidence or data to support the claim that these stocks are ticking portfolio bombs, other than citing their high RSI values and a single report from QuinStreet that has no clear connection to the stocks' performance or prospects. A more thorough analysis would include factors such as earnings, revenue, growth, dividends, valuation, competition, regulation, customer feedback, etc.
3. The article seems to have an negative bias towards these stocks and their investors, as it uses words like "warning", "flashing", "overbought", "ticking", "harm", etc., which evoke fear and urgency in the readers. This could be a way of manipulating the emotions of the readers or creating a self-fulfilling prophecy by driving down the prices of these stocks through panic selling. A more balanced approach would acknowledge both the risks and opportunities that these stocks present, as well as the possible reasons why some investors might still be interested in them despite their challenges or uncertainty.
