I ran a stock screener for companies with rapidly growing revenues and sales over the past year and came across Ciena. This company provides the hardware (routers, fiber optic lines) and software necessary for the optimal 5g network performance and controls about 25% of the market share in this industry. Also the stock's P/E ratio indicates that it is currently undervalued. Not as exciting or a fast mover like biotechs but this one could be a big winner the next few years.
