- The Signal app has nothing to do with a small company, Signal Advance, whose stock price multiplied 12-fold in two days.
- Elon Musk suggested that his followers use the messaging app, but some people bought the unrelated stock.
- Similar things have happened in the past to companies that have names similar to Zoom Video and Twitter.
Shares of an obscure and unrelated company called Signal Advance, which trades over the counter, surged 527% on Thursday and another 91% on Friday, climbing from 60 cents to $7.19.
The Signal that Musk was referring to is operated by a nonprofit and serves as an alternative to texting apps like Facebook Messenger, WhatsApp and Apple's messaging service. That Signal took to Twitter on Friday to clarify that it has nothing to do with Signal Advance.
"It's understandable that people want to invest in Signal's record growth, but this isn't us," Signal wrote. "We're an independent 501c3 and our only investment is in your privacy."
It's a familiar issue on Wall Street.
In April 2019, on the day Zoom Video Communications held its hotly anticipated market debut under the ticker symbol ZM, a Chinese company named Zoom Technologies jumped more than 80% in two hours of trading. The stock gave up most of those gains that day, closing up 10%.
Six years earlier, as investors were waiting for Twitter's IPO, shares of Tweeter Home Entertainment Group rose more than 1,000%.
Signal Advance was founded in Texas under the name Biodyne in 1992 and provided services to medical and legal workers. The company shifted its focus to using technology in health care and changed its name to Signal Advance. The thinly traded stock hit the market in 2014.
Signal Advance is so small that it doesn't report financials with the SEC. As of March 2019, it had no full-time employees other than CEO Chris Hymel, who did not immediately respond to a request for comment.
Because of the swarm of unintended investor interest, the company now has a market cap of $660 million, up from $55 million two days ago. Prior to Thursday, the stock had traded under $1 since 2015.
The Signal messaging app, backed by the Signal Technology Foundation, "runs entirely on donations," according to a New Yorker article published in October.
The group had other concerns following Musk's tweet to his more than 41 million followers. Signal said Thursday that there were technical issues with verifications because "so many new people are trying to join."
Both the technical snafu and the wild trading of an unrelated stock underscore Musk's growing influence. On Thursday, he became the world's richest person thanks to Tesla's almost 800% increase in market cap over the past year. On Friday, Tesla became the fifth most valuable public company in the U.S., surpassing Facebook.
