The Federal Reserve's' Walsh Era 'is Coming! Nasdaq 100 Historical Performance+New Chairman's Impact Prediction! The performance of the Nasdaq 100 after the appointment of the 4th chairman in history Over the past 12 months, there have been 3 increases and 1 decrease, indicating a long-term bullish trend. Greenspan suffered the most on the eve of the collapse; Yellen/Powell have the strongest technology repair market. Core rule: The market trades not by the chairman's name, but by the position of the cycle at the time of taking office (bull/bear/post crisis). The core differences in style between Walsh and Powell Policy philosophy: Walsh radical reform (correcting excessive currency issuance and reshaping credibility); Powell is data-driven and asymptotically balanced. Inflation perspective: Walsh zero tolerance (policy mistakes); Powell acknowledges external shocks. Policy tool: Walsh's biggest difference - "interest rate cut+significant balance sheet reduction" in parallel (unconventional combination); Powell's interest rate is dominant, following traditional logic. Positioning: Walsh shrinks its "mission spread" and returns to inflation+employment; Powell sticks to the framework. Style summary: Walsh=higher uncertainty+greater volatility; Powell=predictable+low impact. Walsh's prediction on the trend of the Nasdaq after taking office Short term (same day~30 days): There is a high probability of fluctuating adjustments (similar to Powell's -3.9%), and policy uncertainty is pushing up the VIX. Last 3 months: Key window, aggressive "interest rate cuts+balance sheet reduction" or creating roller coasters, with fluctuations higher than historical averages, expected to be -5% to+8%. The last 12 months: depending on the periodic resonance. If inflation is successfully controlled and a soft landing is achieved, similar to Yellen/Powell, they can achieve a 10-20% increase; If the correction is too drastic, there is a risk of phased withdrawal. Overall neutral to high, but the volatility has significantly increased. In the era of Walsh, the Nasdaq will not inevitably soar or plummet due to the "new chairman", the key depends on what cycle and policy implementation rhythm he takes over. Short term vigilance against bidirectional liquidity shocks, medium - to long-term focus on the effectiveness of anti inflation measures and the performance of technology stocks.
