January 2025 was a bullish month for many Nasdaq-listed names. But that wasn't the case for all of them.

While the Nasdaq-100 index advanced 2.2% in January, a handful of its constituents (including a market favorite) lost quite a bit of ground. Here they are, from least bad to worst:

• Monster Beverage (NASDAQ: MNST): Down 7.3%
• Comcast (NASDAQ: CMCSA): Down 10.3%
• Nvidia (NASDAQ: NVDA): Down 10.6%
• Electronic Arts (NASDAQ: EA): Down 16%
• On Semiconductor(NASDAQ: ON): Down 17%

Not every one of these stumbles has a specific catalyst. Monster Beverage, for example, mostly continued to peel back from an overheated rally that peaked in November 2024.

Comcast's stock fell in response to a drop in last quarter's broadband customers, while Electronic Arts shares crashed after it lowered its full-year revenue forecast thanks to tepid demand for its latest soccer video game title.

As for On Semiconductor — last month's biggest Nasdaq-100 loser — shares were already lagging headed into the new year, but this sell-off accelerated after a Truist analyst downgraded the stock from a buy to a hold on concerns of weak demand.

Just don't jump to sweeping conclusions

Now what? Obviously, market-defying sell-offs are alarming. They are also warning signs of bigger potential problems ahead. Don't take these warnings lightly.

Just bear in mind that there may still be some lingering bearish volatility left to wring out.
