The past trading week saw a more calm, generally optimistic, market environment amid the temporary pause in tit-for-tat tariffs, buoyed further by a flurry of corporate earnings for the first quarter of the year.

On a week-on-week basis, the tech-heavy Nasdaq rallied the most, up 3.4 percent, followed by the Dow Jones with 3 percent, and the S&P 500 by 2.9 percent.

Beyond the major indices, 10 firms stood out, booking double-digit gains as high as 48 percent, thanks to better-than-expected earnings and outlook.

In this article, we name this week’s 10 best-performing mid-cap companies 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. The stocks were chosen based on the highest percentage increase in closing prices on May 2 as against their prices a week earlier, or on April 25.
