Sometimes there are gems in the world of low-cost shares. But when we invest in penny stocks, we need a good eye and a strong set of nerves. 📉 Here are some of my observations for potential candidates on the NASDAQ that are still trading under a dollar and are in promising industries. 🕵️‍♂️

1.Akoustis Technologies $AKTS (+0 %) - This company is in the business of radio frequency solutions used in 5G and WiFi technology. The demand for communication technology is growing and with the potential to increase sales, AKTS could benefit in the long term. 📡

2.Emcore Corporation $EMKR - A small player in the aerospace industry that specializes in autonomous systems and drone technology. The defense industry is interested in these technologies, which offers EMKR a potential growth opportunity in an emerging market. 🚀

3.FuelCell Energy $FCEL - This is an alternative energy company that focuses on fuel cells. The world is looking for clean energy sources and if fuel cell technology becomes more relevant, FCEL could gain significant value. 🌱⚡

These are not recommendations for everyone. Penny stocks are volatile and risky, but those who understand the risk and keep an eye on developments can see exciting opportunities in these companies. 🧐
