Robinhood's (HOOD) shares rise after announcing S&P 500 entry. Alibaba (BABA) sees resurgence with new AI model release. Tesla (TSLA) surges over 25% in six months amid Elon Musk's potential $1 trillion pay package. Ramzan Karmali analyzes today's trending tickers.

Robinhood Markets Inc. (HOOD) saw its stock price rise by approximately 7% after the close of trading on September 22, 2025, following its unexpected addition to the S&P 500 index. The inclusion of the fintech company, effective as of September 22, 2025, underscores the growing recognition of fintech firms in the broader market and highlights Robinhood’s evolving role in the financial services landscape [1].

In contrast, MicroStrategy Inc. (MSTR) experienced a nearly 3% drop in its stock price in after-hours trading after being excluded from the S&P 500, despite meeting all the criteria for the index. The exclusion of MicroStrategy, a major corporate Bitcoin holder, reflects the S&P 500’s criteria and selection process, which considers factors beyond just financial metrics [1].

AppLovin Corp. was also added to the S&P 500, further emphasizing the index’s focus on innovative technology firms. The addition of AppLovin, a leading mobile app and advertising technology company, highlights the index’s responsiveness to market dynamics and the growing importance of fintech and tech sectors [1].

Meanwhile, Alibaba Group (BABA) has seen a resurgence with the launch of its Qwen-Image, a 20B-parameter open-source AI model. The model, launched in August 2025, combines cutting-edge multimodal capabilities with an open-access model, positioning Alibaba to dominate the AI-driven visual creation market [2].

Tesla Inc. (TSLA) has surged over 25% in the past six months amid speculation that Elon Musk could receive a potential $1 trillion pay package. The stock's performance reflects investor optimism about the company’s future prospects and Musk’s leadership [3].
