AmpliTech Group Inc. (AmpliTech (AMPG)) shares surged nearly 12% in premarket trading Tuesday after the company announced a key Open RAN interoperability milestone. The move came even as broader market gains remained modest, with S&P 500 futures rising about 0.5%.

Open RAN Milestone Boosts Sentiment

AmpliTech said it participated in the O-RAN ALLIANCE Global PlugFest Spring 2026 as the only vendor showcasing a 64T64R Massive MIMO radio. The company said the event validated its technology in independent, multi-vendor Open RAN environments and highlighted its role in advancing AI-RAN development.

The PlugFest is designed to test interoperability among equipment from different vendors, a key requirement for Open RAN deployments. AmpliTech said its participation demonstrated that its radio technology can integrate effectively within complex multi-vendor networks.

Technical Picture Remains Strong

The stock continues to trade in a strong uptrend. Shares were about 66.5% above their 20-day simple moving average of $4.41 and roughly 127.1% above their 200-day moving average of $3.24.

At $7.35, the stock has also moved above its previous 52-week high of $6.59, signaling a breakout to new highs.

Momentum indicators, however, suggest the rally may be becoming stretched. The relative strength index stood at 73.33, placing the stock in overbought territory. While that often reflects strong buying interest, it can also increase the risk of short-term pullbacks.

From a trend perspective, the 20-day moving average remains above the 50-day moving average, a bullish near-term signal. However, the 50-day moving average is still below the 200-day moving average following a death cross earlier this year.

Key technical support sits near the 20-day moving average at $4.41, while the former 52-week high of $6.59 could serve as an important reference level if the breakout loses momentum.

AMPG Stock Price Activity: AmpliTech Group shares were up 11.87% at $7.35 during premarket trading on Tuesday. The stock is trading at a new 52-week high, according to market data.
