The stock market is unpredictable, with prices soaring one day and tumbling the next. So, where should you put your hard-earned money? Here’s a quick recap of the stocks that gained and lost ground this past month, along with some insights on where to invest.

Stocks on the Rise

Both Warner Bros Discovery (WBD) and DoorDash (DASH) stocks performed well this September. 

WBD climbed an impressive 66.52% last month—a major leap for any company. Warner Bros is a U.S.-based mass media and entertainment company known for its wide range of content, from film to television to news. The stock’s sharp rise came after the announcement of its merger with Paramount Skydance. While that merger news boosted prices, it also made the stock more volatile, so investors should proceed with caution. 

DASH also saw growth in September, with its stock up 9.64%. Unlike Warner Bros, DoorDash appears steadier, as the company leads the food-delivery industry and reported a very strong second quarter. Its performance signals a positive growth outlook, making it an appealing option for long-term investors.

Stocks that Fell

On the flipside, Lululemon (LULU) and The Trade Desk (TTD) both declined in September. 

Lululemon, the Canadian luxury athletic apparel brand, dropped 12% over the month, despite earlier analyst predictions of steady gains. The decline came after the company lowered its full-year outlook, citing weaker U.S. demand along with a negative effect of tariffs on profit margins. 

Meanwhile, The Trade Desk, an advertising technology company based in Ventura, California, fell about 10.3%. The drop followed Amazon’s announcement of a partnership with Netflix, giving marketers a new way to buy ads on the streaming service. This move could cut into The Trade Desk’s market share and poses a serious challenge for the company going forward.

As always, the market remains full of opportunities and risks. Keep an eye on these companies as we move into the next quarter, and remember to invest carefully.
