Thanks to the downward inflation rate and the hot emerging technologies such as artificial intelligence (AI), US stocks are back in 2023, of which technology stocks are the biggest driving force. The Nasdaq 100 technology index $NASDAQ 100(NDX)$ is up 45% since January 1. Despite the poor performance last year, the technology sector offers investors reliable returns over the long term, and it is a high-quality long-term investment. Innovation in the technology market is an inexhaustible source of revenue and stock price growth for technology companies. If you want to catch the hottest tech trends of 2023, these 3 tech stocks are worth considering in September. 图片 1. Microsoft $Microsoft(MSFT)$ has a market capitalization of $2.4 trillion, making it the second most valuable company in the world after $Apple(AAPL)$ . Thanks to the success of platforms such as Windows, Office, Xbox and Azure, the share price has risen 192% over the past five years. However, the biggest reason to buy the tech giant's stock in September is the long-term potential of AI. In 2019, Microsoft invested $1 billion in OpenAI, obtained exclusive licenses for several AI models, and became the primary distributor of ChatGPT. In addition, the company has used OpenAI's technology to make AI upgrades to many of its popular products, including Office and Azure. In early August, Microsoft shares fell 2% after Microsoft executives announced that AI revenue growth would slow. However, if the time period is extended to the next 5 to 10 years, AI revenue may explosion, so now is the opportunity to buy the dip. 2. Amazon By far, Microsoft's biggest competitor is $Amazon.com(AMZN)$ . The company holds a leading market share in the cloud computing and e-commerce markets, and there is great potential for AI development. Amazon shares plunged nearly 50% in 2022 as retail profits fell again, but they have rebounded 64% so far this year, thanks to the recovery in e-commerce and the AI boom. The company reported an operating profit of more than $3 billion in North America in the second quarter of 2023, compared with a loss of $627 million a year earlier, indicating that the retail decline has ended. At the same time, Amazon is also investing heavily in AI, with the company's cloud platform Amazon Web Services (AWS) launching several new AI tools this year. In June, Amazon announced plans to jointly develop chips in order to compete with $NVIDIA Corp(NVDA)$ , the leader of the chip market. Despite the recent gains, Amazon's stock price is still down 26% from its July 2021 high, adding to the company's huge growth potential, so September is a great buying opportunity. 3. Advanced Micro Devices Advances in AI, cloud computing, gaming, consumer technology and other technologies are now inseparable from chips, so chipmakers like $Advanced Micro Devices(AMD)$ will be the winners behind these technology trends. AMD's share price has risen 335% over the past five years, while annual revenue has risen 264% and operating profit has risen 180% over the same period. The reason why the company has achieved such rapid growth is that many technology companies need its hardware to upgrade their products. For example, in 2020, AMD became the exclusive chip supplier for $Sony(SONY)$ PlayStation 5 and Microsoft Xbox X | S game consoles. The company's chips have since been used in a variety of handheld gaming devices, laptops and PC, as well as cloud platforms such as Azure and Google Cloud.
