But the crypto market has been very volatile recently, as investors have sought safer investments amid the Iran conflict, tariff threats, and the disruption of many companies by artificial intelligence (AI). If you're interested in investing in technology but don't want the inherent volatility that comes with owning cryptocurrencies, here are two great tech stocks that have great long-term potential for gains. Image source: Getty Images. Not all AI leaders are overpriced There's a lot of debate over whether AI stocks are in a bubble, as the value of many tech stocks has soared over the past few years. But while some companies are likely overvalued, many are increasing sales and earnings quickly -- and Taiwan Semiconductor (TSM 2.82%) is a great example of the latter. Taiwan Semiconductor, also called TSMC, is the leading processor manufacturer with 70% global market share. In the fourth quarter, its sales rose 26% to $33.7 billion, and its earnings popped 35% to $3.14 per American depositary receipt. TSMC benefits from its dominant position in AI processor manufacturing, and management estimates more growth this year, with sales expected to increase 30% in 2026 compared to last year. One thing that's helping TSMC grow at such a steady pace is the company's semiconductor manufacturing know-how, which has enabled it to stay ahead of Samsung and Intel. While other companies make similar processors, they can't match TSMC's efficiency. But maybe one of the most impressive things about TSMC is that its stock is still relatively inexpensive. Taiwan Semiconductor's shares have a price-to-earnings (P/E) ratio of about 32, which is cheaper than the tech sector average P/E ratio of 35.

For one, its Gemini chatbot had more than 750 million monthly active users at the end of 2025 -- an increase of about 67% in six months-- an impressive achievement amid a fiercely competitive AI agent race. What's more, the company recently inked a multiyear deal with Apple, reportedly worth several billions of dollars, that will make Gemini the underlying AI model for an upcoming Siri update. In addition to its AI gains, Alphabet is also a key player in the emerging quantum computing market. The company released its Willow quantum computing chip in 2024, which can substantially reduce error rates. Just last year, it ran a verifiable algorithm on a quantum computer 13,000 times faster than on a supercomputer.

That's notable considering the scope of quantum computing, which could be a $100 billion market by 2035. To top it all off, Alphabet's stock has a P/E ratio of just 28 right now, making its shares a downright bargain.Read NextMar 20, 2026 •By John Ballard2 Unstoppable Artificial Intelligence (AI) Stocks to Buy Right Now for Less Than $1,000Mar 20, 2026 •By Adria CiminoWhat Are the Best AI Stocks to Buy While Big Tech Is Spending $690 Billion on Infrastructure?Mar 18, 2026 •By Stefon WaltersThink It's Too Late to Buy Taiwan Semiconductor Manufacturing Company Stock?
