The stock price of BlackBerry (BB) increased by over 2.5% during intraday trading today. There are no company-specific reports or notable regulatory filings that are driving up the price so it appears there are external factors at play.
In this case, it appears that the stock price is being driven by a sympathy play associated with a meme stock short squeeze rally. There has been a surge in discussions about meme stocks on message boards like Reddit, Discord, Twitter, StockTwits, and Facebook Groups today.
