July 5 (Reuters) - Shares of headphone maker Koss Corp. ( KOSS )

soared for the second session in a row on Friday,

closing at $13.35 a share, after trading as high as $18.50 early

in the day, as social media posts speculated that a post by meme

stock influencer Keith Gill indicated his interest in the

company.

Some followers of Gill, known to his online followers as

'Roaring Kitty', on social media pointed to cryptic images he

posted in May of a microphone posted against the backdrop of the

U.S. flag. The image was shown as an emoji that scrolled across

the end of a video.

That led to speculation on Reddit, such as

Otherwise-Category42's post on the sub-Reddit devoted to

GameStop ( GME ) that has been tracking Gill's return, that 'Roaring

Kitty' would become a buyer of Koss ( KOSS ) shares on or around July 4,

the U.S. Independence Day holiday. The poster also documented

similarities between Koss ( KOSS ) and GameStop ( GME ). Others on Reddit,

however, were skeptical as the U.S. flag emoticon featured a

microphone and not headphones.

Koss' ( KOSS ) gain on Friday follows a 143.8% jump during

Wednesday's abbreviated trading session and brings its gains for

the week to nearly 230%. In premarket trading on Friday, the

stock briefly traded as much as 74% higher.

"There are absolutely no fundamental reasons why this

company might be worth four times what it was at the beginning

of the week," said Steve Sosnick, market strategist at

Interactive Brokers.

Nearly half of Koss's ( KOSS ) 9.25 million shares are held by

insiders and such a small public float means even small upticks

in buying can result in exaggerated moves, Sosnick and other

traders noted. By early afternoon Friday, trading volume had

topped 47 million shares. Its average daily trading volume over

the last 60 days is less than 2 million, traders noted.

Koss ( KOSS ) could not be reached for comment.

Gill, who did not return calls or e-mails seeking comment,

has not made any public comments about Koss ( KOSS ). In mid-June, he

disclosed a position of 9 million shares in GameStop Corp. ( GME )

and most recently, revealed in a filing with U.S.

regulators that he acquired a 6.6% stake in online pet food

retailer Chewy Inc. ( CHWY ).

Prior to making the Chewy investment, Gill posted a series

of images about a cartoon dog on X that followers believe

foreshadowed that disclosure. The earlier video had also

featured an emoji of a similar cartoon dog. That sent "Roaring

Kitty" fans in search of any hidden meanings in other stocks.
