An analysis of the underlying logic behind it. The screenshot of the **Fear & Greed Index** actually provides the most intuitive answer. A month ago, the index fell to **18 (Extreme Fear)**, and now it has rebounded to **66 (Greed)**. This extreme V-shaped reversal is usually caused by the resonance of the following factors: - **Sentiment Repair and Short Squeeze:** From March to April, due to geopolitical tensions (US-Iran conflict) and macroeconomic uncertainties, the market was in a state of extreme panic, with a large amount of capital seeking safe havens. When the worst-case scenarios (such as full-scale war, prolonged blockade of the strait) did not occur, or were digested by the market, a "relief" retaliatory rebound followed. Short positions from earlier were forced to cover and buy, and this force, combined with bottom-fishing capital, directly led to the short squeeze. - **Algorithm and Quantitative Capital Fueling the Fire:** Once the index breaks through key resistance levels (like the S&P 500 strongly breaking through the 125-day moving average in the screenshot), Wall Street's quantitative models and trend-following funds (CTAs) are automatically triggered, buying in blindly. This machine-driven buying doesn't care about whether the price is "high" or not; it just pushes along with the momentum. - **The Leverage Effect of Semiconductors:** SOXL is a 3x leveraged long semiconductor ETF. The semiconductor sector (e.g., NVDA, TSM, ASML) is itself the area with the strongest profit certainty and most powerful momentum for capital concentration in the current US stock market. With a slight push from the underlying assets, amplified by the 3x leverage, you see the exaggerated "18-day winning streak" and weekly/monthly charts that are almost at a 90-degree angle. ### Predicting the Next Scenarios and Response Strategies Since the first wave of the "golden pit" at the bottom has already been missed, the core now is to **control your hands and patiently wait for the next high-probability hitting zone**. - **Scenario One: High-level Volatility and Distribution, Followed by a Sharp Pullback (Most Likely)** After the short squeeze ends, as the earnings season deepens or macroeconomic data causes disturbances, momentum will gradually weaken. The market will see a K-line with high volume but stagnant gains (like a long upper shadow or a doji), followed by a daily-level correction. **Response:** Open TradingView, look for daily-level bullish divergences, or wait for the price to pull back to key EMA support levels (e.g., 20-day or 50-day moving averages) before considering building a base position in batches. - **Scenario Two: Sector Rotation, Semiconductors Cool Off, Other Tech Stocks Catch Up** Capital may flow out of the overextended semiconductor sector to find giants with relatively reasonable valuations and lagging gains. **Response:** Don't just stare at SOXL. Look for targets whose technical patterns have just broken out or are forming a right shoulder at the bottom. When one door closes, another opens. Shifting your focus can effectively alleviate FOMO. $Direxion Semicon Bull 3X(SOXL.US) $iShares Semiconductor ETF(SOXX.US) ### Related Stocks - [SOXX.US](https://longbridge.com/en/quote/SOXX.US.md) - [SOXL.US](https://longbridge.com/en/quote/SOXL.US.md) - [SOXS.US](https://longbridge.com/en/quote/SOXS.US.md) - [CP00062.US](https://longbridge.com/en/quote/CP00062.US.md)
