Foolish take

Activist investing firm Coliseum Capital Management has been adding to its stake in Sonos since 2022 and continued building this position in its latest quarter.

These more recent purchases are somewhat interesting as Sonos' stock has roughly doubled from its lows in April this year.

This persistent buying, despite the high price tag, could be seen as a bullish sign for investors. However, since Coliseum is typically an activist investor, the buying may be more about building equity and perhaps getting seats on the board, rather than timing a "buy the dip" opportunity.

From a Foolish perspective, I'm not in love with Sonos' stock, as it has struggled to grow revenue and earnings over the last five years.

While it may be a leader in consumer mindshare in its premium audio niche, consistently reporting top-tier customer loyalty and satisfaction figures, it really hasn't done much for investors.

In this sense, it is the perfect investment for an activist like Coliseum, which could try to cut costs, demand cash returns to shareholders, or shake up management at the underperforming company.

Ultimately, hardware consumer goods companies not named Apple (NASDAQ:AAPL) tend to scare me away, so I'm personally not too interested in Sonos. That said, I can see the reasoning behind Coliseum's interest in the company as a quintessential turnaround stock.
