Today's biggest winners and losers in the stock market, a look at the notable movers for the week:
On this episode of Stock Movers:

- Chewy (CHWY) shares are down as much as 8.8% on Tuesday, hitting their lowest intraday level since May 2024, after the online pet retailer presented at the JPMorgan Technology, Media & Communications Conference. The company provided some cautious commentary during the event, saying that it’s seeing a more “stretched” consumer now than it did at the beginning of the year.

- Costco Wholesale (COST) remains well-positioned to gain market share on its strong value and steady demand for essentials, though higher fuel prices may pressure near-term margins, Oppenheimer said Tuesday in a report. Oppenheimer expects fiscal Q3 earnings of $4.75 a share, trailing the Wall Street consensus of $4.98, as higher fuel costs and a heavier e-commerce and pharmacy mix may outweigh a benefit from inventory accounting. Results are due May 28.

-Crowdstrike (CRWD) shares are edging higher on Tuesday, hitting a new all-time high as buyers lean into fresh bullish analyst commentary.
