To receive stock news alerts and stay up to date with information about stockouts, there are several options that may be useful:

1. Investment Apps:
Many investing apps offer alert features for market news and stock movements. Some popular ones include Robinhood, Webull, TD Ameritrade, E*TRADE, among others. These apps allow you to set up custom alerts based on specific criteria such as price movements, trading volume, relevant news, etc.

2. Finance Websites:
Sites like Yahoo Finance, Bloomberg, CNBC, MarketWatch, among others, offer email alert services or push notifications on their mobile apps. You can set up these alerts to receive important news about specific companies or the market in general.

3. Social Networks and Financial Forums:
Following financial news companies' social media accounts and participating in forums like Reddit (for example, the r/stocks subreddit) can be a way to stay up to date with the latest news and stock discussions.

4. Email and RSS Alerts:
Many financial websites offer sign-ups for email newsletters or RSS feeds. These methods can be effective for receiving updates directly to your inbox or RSS reader.

5. Trading and Broker Platforms:
In addition to the apps mentioned, some trading platforms and brokers offer alert services directly on their platforms. Check if your broker offers this functionality and how to set it up.

6. Google Alerts:
Setting up Google Alerts for specific terms related to the stocks you're interested in can be another way to receive email notifications about breaking news.
