美国佛罗里达大学金融学教授Alejandro Lopez-Lira表示,大语言模型在预测股价方面可能很有用。在近期一篇未经同行评审的论文中,他写道,在使用ChatGPT分析新闻标题对一只股票是有利还是不利之后,他发现ChatGPT预测次日回报方向的能力远好于随机水平。不过这项实验的细节也表明,大语言模型距离能够胜任金融行业的工作还有很长的路要走。

Securities trading is offered to self-directed customers by Webull Financial LLC, a broker dealer registered with the Securities and Exchange Commission (SEC). Webull Financial LLC is a member of the Financial Industry Regulatory Authority ( FINRA ), Securities Investor Protection Corporation ( SIPC ), The New York Stock Exchange ( NYSE ), NASDAQ and Cboe EDGX Exchange, Inc ( CBOE EDGX ).

Webull Financial, LLC is a CFTC registered Futures Commission Merchant and NFA Member. Futures and futures options trading involves substantial risk and is not suitable for all investors. Please read the Risk Disclosure Statement and other relevant Futures Disclosures located at www.webull.com/fcm-disclosures prior to trading futures products. Futures accounts are not protected by the Securities Investor Protection Corporation (SIPC).

Advisory accounts and services are provided by Webull Advisors LLC (also known as "Webull Advisors"). Webull Advisors is an Investment Advisor registered with and regulated by the SEC under the Investment Advisors Act of 1940. Registration does not imply a level of skill or training. See additional information on the Disclosures webpage. Trades in your Webull Advisors account are executed by Webull Financial LLC.

Webull Financial LLC is a member of SIPC, which protects securities customers of its members up to $500,000 (including $250,000 in any cash awaiting reinvestment). An explanatory brochure is available upon request or at www.sipc.org . Webull Financial LLC’s clearing firm Apex Clearing Corp has purchased an additional insurance policy. The coverage limits provide protection for securities and cash up to an aggregate of $150 million, subject to maximum limits of $37.5 million for any one customer’s securities and $900,000 for any one customer’s cash. Similar to SIPC protection, this additional insurance does not protect against a loss in the market value of securities.

Options trading entails significant risk and is not appropriate for all investors. Option investors can rapidly lose the value of their investment in a short period of time and incur permanent loss by expiration date. Losses can potentially exceed the initial required deposit. You need to complete an options trading application and get approval on eligible accounts. Please read the Characteristics and Risks of Standardized Options before trading options.

All investments involve risk, and not all risks are suitable for every investor. The value of securities may fluctuate and as a result, clients may lose more than their original investment. The past performance of a security, or financial product does not guarantee future results or returns. Keep in mind that while diversification may help spread risk, it does not assure a profit or protect against loss in a down market. There is always the potential of losing money when you invest in securities or other financial products. Investors should consider their investment objectives and risks carefully before investing.

Diversification does not eliminate the risk of experiencing investment losses. Margin trading increases risk of loss and includes the possibility of a forced sale if account equity drops below required levels. Margin is not available in all account types. Margin trading privileges are subject to Webull Financial, LLC review and approval. Leverage carries a high level of risk and is not suitable for all investors. Greater leverage creates greater losses in the event of adverse market movements.

Investors should be aware that system response, execution price, speed, liquidity, market data, and account access times are affected by many factors, including market volatility, size and type of order, market conditions, system performance, and other factors. Market volatility, volume and system availability may delay account access and trade executions.

Free trading of stocks, ETFs, and options refers to $0 commissions for Webull Financial LLC self-directed individual cash or margin brokerage accounts and IRAs that trade U.S. listed securities via mobile devices, desktop or website products. A $0.55 per contract fee applies for certain options trades. Relevant regulatory and exchange fees may apply. Please refer to our Fee Schedule for more details.
