KOSS is trading 6.65% down at $3.06 now, alongside a 4.30% decline in consumer discretionary (XLY) during the session; this does not establish a company-specific catalyst. - No company-specific announcement explaining the November 5 decline surfaced in the search. - Koss’s October 29 quarterly report showed lower sales and a net loss; it predates the move. - Broader-market reports are mixed, limiting confidence in the sector explanation.
