SIGL
SIGL to lose 90%"When Tesla CEO Elon Musk urged his Twitter followers on Thursday to “use Signal,” he meant the encrypted messaging app. Some people appear to have taken it the wrong way.
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."
Naturally, it will soon lose all this gain and return to its usual pricing.
