10 Firms That Soared Last Week

Last week saw volatile trading in the stock market as investors scrambled to react from a series of positive and negative catalysts which sparked buying and selling positions across the board.

On Friday alone, Wall Street’s major indices fell into the red territory over renewed fears of growing trade tensions from some of the world’s largest economies, coupled with expectations of a higher inflation rate.

However, 10 firms defied a broader market slump, posting impressive gains in just a week’s trading.

To come up with last week’s biggest advancers, we considered only the stocks with at least $2 billion in market capitalization and $5 million in daily trading volume.

10. Magnite Inc. (NASDAQ:MGNI)

Magnite saw its share prices grow by 23 percent in just a week, ending Friday’s trading at $21.17 apiece as investor sentiment was boosted by its recent partnership with Elon Musk’s X, formerly Twitter.

While the specific terms of the partnership were not disclosed, MGNI, known for its technology that aids web publishers, application developers, and streaming TV providers in managing and selling advertisements, would serve one of X’s supply-side partners (SSP) by offering a more streamlined advertising system to X and giving advertisers the option to include or exclude the social media platform’s inventory from their media buys.

A representative from MGNI was said to have confirmed the partnership, saying that the collaboration would benefit advertisers leveraging the MGNI platform.

MGNI joins Google and InMobi in providing SSP solutions to X.

9. Affirm Holdings Inc. (NASDAQ:AFRM)

Affirm Holdings grew its share prices by 23 percent in just a week’s trading, ending Friday at $75.22 apiece, with investor sentiment said to be fueled by the company’s strong earnings performance in the second quarter of fiscal year 2025.

In its earnings release last week, AFRM reported a net income of $80.36 million during the last quarter, reversing a net loss of $166.9 million in the same period a year ago.

Revenues also jumped by 46 percent to $866 million from the $591 million reported year-on-year.

Investors also took path from AFRM CEO Max Levchin’s bullish outlook for the company this year, saying that AFRM is only five months away from turning the firm to profitability.

“But it should be apparent to a casual observer that we are nearly there today—mark it zero,” he said.

AFRM is a technology services company providing financial services to shoppers and merchants.
