We recently published a list of 10 Unexpected Market Movers—What Propelled Double-Digit Gains? In this article, we are going to take a look at where QuidelOrtho Corporation (NASDAQ:QDEL) stands against other Thursday’s top-performing stocks.

The stock market extended its winning streak on Thursday as investors cheered President Donald Trump’s trade deal framework between the United States and the United Kingdom.

Among Wall Street’s major indices, the tech-heavy Nasdaq rallied the most, up 1.07 percent, followed by the Dow Jones, up 0.62 percent, and the S&P 500, gaining 0.58 percent.

According to Trump, the Oval Office outlined a trade deal framework. While a 10-percent baseline tariff will remain for imported goods from the UK, it could be the low end of deals with future countries.

“The final details are being written up,” Trump said. “In the coming weeks, we’ll have it all very conclusive.”

Beyond the major indices, 10 firms stood out, booking double-digit gains amid a flurry of fresh developments such as optimistic revenue guidance and impressive earnings performance, among others. In this article, let us explore Thursday’s 10 top-performing stocks and detail the reasons behind their gains.

To come up with the list, we considered only the stocks with a $2-billion market capitalization and $5-million trading volume.

QuidelOrtho Corporation (NASDAQ:QDEL)

QuidelOrtho saw its share price expand by 41.04 percent on Thursday to close at $36.46 apiece after almost wiping out its net losses during the first quarter of the year.

In a statement on Thursday, QuidelOrtho Corporation (NASDAQ:QDEL) said it narrowed its net loss by 99 percent to $12.7 million from $1.7 billion recorded in the same period last year, despite revenues dipping by 2.56 percent to $692.8 million from $711 million year-on-year.

The lag in revenues can be owed to the flat performance of its non-respiratory revenue, which was at $573 million. Meanwhile, respiratory revenues ended at $120 million, marking an 11 percent growth year-on-year.

For the full year, the company also targets to book between $30 million and $40 million in tariff impact, which it targets to mitigate through cost actions.
