Up until this January, Koss (NASDAQ: KOSS) was a penny stock that many investors likely hadn't heard of. The headphone maker's growth was unimpressive, and its stock price had remained below $5 for years.
However, Koss' sluggish growth quietly attracted a lot of short-sellers, making it a ripe target for a Reddit-fueled short squeeze like the one that already propelled GameStop's (NYSE: GME) stock to all-time highs.
As a result, Koss' stock price abruptly jumped from $3.34 to $10 between Jan. 22 and Jan. 26, then skyrocketed to an intraday high of $127.45 on Jan. 28. The stock price closed at $41.96 that day, but it rallied again to $64 on Jan. 29.
