Short-Term Bullish Momentum Drives AMPX Higher
AMPX’s 9.7% intraday surge is fueled by a combination of technical momentum and options-driven speculation. The stock’s price has pierced above the 30-day moving average (7.50) and is now trading near its 52-week high of $9.66. While no direct company news triggered the move, the options chain reveals aggressive call buying in October 2025 contracts, particularly at the $9 and $10 strike prices. High implied volatility (91.19%–96.38%) and leveraged ratios (8.37%–12.28%) in these options suggest traders are capitalizing on a short-term bullish trend. The MACD histogram (0.09) and RSI (58.6) further confirm a shift in momentum, with the stock now trading above its 200-day average (3.93) by over 125%.
