3 Top Tech Stocks Under $20 per Share

It can be intimidating to invest in the tech sector's top stocks, which often cost hundreds to thousands of dollars for a single share. Most brokerages make it easier to invest in those stocks through fractional shares, but some investors might still prefer to buy even lots of 100 shares, which are easier to track or use for covered calls.

Investors should remember that a stock's trading price never defines how cheap or expensive it actually is. For example, a stock that trades at a single-digit price with a triple-digit price-to-earnings ratio is still usually more expensive than a stock that trades at a triple-digit price with a single-digit price-to-earnings ratio.

That said, stocks that trade at less than $20 a share might still be considered more manageable than higher-priced stocks. So today, we'll take a closer look at three promising tech stocks that trade under that threshold: the solid-state battery maker QuantumScape (NYSE: QS), the Taiwanese contract chipmaker United Microelectronics (NYSE: UMC), and the Bitcoin miner Marathon Digital (NASDAQ: MARA).

1. QuantumScape

QuantumScape produces solid-state batteries that are powered by solid electrolytes instead of the liquid electrolytes used in lithium-ion batteries. Solid-state batteries are generally less volatile, more resistant to high temperatures, less susceptible to leaks and fires, and can charge faster than lithium-ion batteries.

QuantumScape is developing solid-state batteries for the electric vehicle (EV) market that can be fully charged in less than 15 minutes and have a range of 400-500 miles. Those batteries could potentially replace traditional lithium-ion batteries for EVs, which require roughly 30 minutes to charge for a range of approximately 300 miles.

QuantumScape hasn't commercialized any of its batteries nor generated any meaningful revenue yet, but its biggest backer is Volkswagen. It's gradually shipping its first samples this year, and analysts expect it to generate just $2 million in revenue in 2024 and $15 million in revenue in 2025.

That doesn't seem like a lot of revenue for a company with an enterprise value of $2.5 billion, but QuantumScape's revenue could skyrocket over the next decade as automakers switch to solid-state batteries. If you believe QuantumScape will remain a major player in this nascent market, then it could be a great buy at $7 a share.

2. United Microelectronics

United Microelectronics, better known as UMC, is Taiwan's second-largest contract chipmaker after Taiwan Semiconductor Manufacturing. It's often overshadowed by TSMC because it manufactures larger, older, and cheaper chips -- but it's still a crucial cog in the global semiconductor supply chain.
