Koss shares surge 12.56% after-hours amid meme stock rally reviving retail investor interest.

think> Okay, let's tackle this query step by step. The user wants me to act as a financial analyst explaining Koss's stock price movement based on recent news. The stock went up 12.56% after hours. First, I need to check the input data for relevant news events. Looking at the news provided, there are several entries. The most recent one is from Zacks 5 days ago mentioning Koss returned to earnings in Q1 with strong DTC growth but the stock was down 6%. Then there's a GlobeNewswire report 11 days ago about Q1 results. There's also a Barchart article from 3 months ago about a meme stock rally involving KOSS. Wait, the stock is up 13.20% in the after-hours session. The Zacks article says the stock was down 6% despite Q1 earnings, which seems contradictory. But maybe there's a newer event. The latest news in the list is the Zacks article from 5 days ago. However, the stock's movement here is after-hours, and the news might be from before. Also, the Barchart article mentions a meme rally reviving Koss, which could be relevant. The user's instruction says to evaluate each news event's relevance. The Zacks article mentions Q1 earnings and DTC growth but the stock was down 6% at that time. However, the current movement is a significant upswing. The Barchart article from 3 months ago talks about a meme stock rally. Meme stocks often surge due to retail investor activity, which could explain a sudden after-hours jump. But there's a conflict here. The Zacks article is 5 days old and mentions a 6% decline, yet the current movement is a 12.56% increase. Maybe the recent after-hours surge is due to the meme stock rally being revitalized, as per the Barchart article. However, the Barchart article is 3 months old. Wait, the user's input lists multiple news events with varying dates. The latest one is Zacks 5 days ago, but the stock was down 6% then. The Barchart article is older but mentions a meme rally. The key here is to find the most relevant news that aligns with the current movement. Since the stock is up in after-hours trading, it's possible that there's a recent event not listed here, but the user provided only the listed news. However, the latest news from Zacks says the stock was down 6% despite earnings, which contradicts the current up movement. The other recent news is from GlobeNewswire 11 days ago. Wait, the Barchart article from 3 months ago mentions a new meme rally and asks if investors should buy KOSS. Meme stocks are often driven by social media and retail traders, which can cause sudden spikes. If the current after-hours surge is due to renewed meme stock activity, that could be the reason. But the Barchart article is from 3 months ago. However, the user's input includes a note that KOSS is tagged as a meme stock in the Milwaukee Journal Sentinel article from 3 months ago. Putting this together, the most plausible reason for the after-hours jump is the meme stock rally, even though the specific news about the rally is older. However, the user's instructions say to use the provided news. The Zacks article from 5 days ago mentions a 6% decline, but the current movement is up. If there's no recent positive news, then perhaps the movement is unrelated. But the user's instruction says to check if the news is relevant. Wait, the user's input shows that the Zacks article says Koss returned to earnings in Q1 on strong DTC growth but the stock was down 6%. If that's the case, then that news would be bearish, but the current movement is bullish. That's a contradiction. The other recent news is from GlobeNewswire 11 days ago about Q1 results. Alternatively, the Barchart article mentions a meme rally and asks if investors should buy KOSS. If the after-hours surge is due to renewed interest in meme stocks, even though the article is old, perhaps there's an ongoing trend not captured in the provided news. But according to the instructions, we must use the provided news. Given that, the most recent relevant news is the Zacks article from 5 days ago, which is bearish (stock down 6% despite earnings), but the current movement is bullish. This contradicts. The other possible relevant news is the Barchart article about the meme rally, which is bullish, but it's 3 months old. If the current movement is due to a new meme rally, but there's no new news provided, then perhaps the movement is not explained by the given news. In that case, the answer would.
