On this episode of Stock Movers, we take a look at some of the week's biggest gainers and decliners:

- Shares of Skyworks (SWKS) surged after CEO Philip Brace updated investors about the status of a key merger. The stock gained 26%, the best five-day session streak since a stretch in February 2009.

- Lululemon's (LULU) turnaround won't be a quick or easy fix as the company cedes market share to rivals and suffers deepening sales declines, according to BMO Capital Markets. BMO initiated coverage of the stock with an underperform rating and a $70 price target, assuming a roughly 29% decline from where the shares closed on Friday. Analysts say the company's "irrelevance with the consumer is showing up in the numbers" and that Lululemon will need to cut prices or liquidate merchandise to reinvigorate demand, which will also pressure margins. During trading on Friday, share rose to just under $100 per share at the close in New York. While the average price target of about $100 is near where shares traded at Friday’s close, the stock has slumped 52% this year and is down more than 80% from a December 2023 record.

- Cooper (COO) led the decliners in health care and lowered its full-year-outlook. On Thursday, it saw its shares tumble as much as 20%, the most intraday since 2008.
