In this article, we focused on the 10 best-performing mid-cap companies on the stock market, which were noticeably dominated by biotechnology and power sectors, and detailed the reasons behind their gains.

10. Riot Platforms Inc. (NASDAQ:RIOT)

Riot Platforms saw its share prices increase by 5.79 percent on Wednesday to close at $12.24 apiece following an investment firm’s bullish recommendation for its stock, while tracking the all-time high rally of Bitcoin.

In a market note, Northland Securities reaffirmed its “buy” recommendation for Riot Platforms Inc. (NASDAQ:RIOT) with a price target of $15. The figure marked a 22.5-percent upside from its latest closing price.

Meanwhile, Riot Platforms Inc. (NASDAQ:RIOT) benefited from Bitcoin’s rally to an all-time high, with the cryptocurrency hitting its highest price of $111,907.49 amid growing institutional interest and a resurgence in retail demand.

Last month, Riot Platforms Inc. (NASDAQ:RIOT) said it mined a total of 450 Bitcoins, a jump of 76 percent from the 255 in the same month last year, but lower by 12 percent from the 514 mined in May 2025.

In the same month, the company also sold 397 Bitcoins, pushing its total holdings to 19,273.

9. Sunrun Inc. (NASDAQ:RUN)

Sunrun bounced back on Wednesday from the previous day’s losses, jumping 6.76 percent to close at $10.51 as investors took heart from an investment firm’s upgraded rating on its stock.

In a market report, Jefferies raised its stock rating for Sunrun Inc. (NASDAQ:RUN) to “hold” from “underperform” previously, while setting a price target of $11, more than double the $5 prior. The new price target represented a 4.66 percent upside from its latest closing price.

According to Jefferies, its upward revision was based on the approval of the One Big Beautiful Bill Act, which maintained solar credits through 2027 and storage through 2035 after previously seeking to axe such credits.

Meanwhile, consumer credit 25D is set to expire by year-end, which Jefferies expects  Sunrun Inc. (NASDAQ:RUN) to benefit from on expectations of more lease and power purchase agreements.

Jefferies, however, remained cautious about the US residential solar market in general, projecting it to decline by double digits by next year as the 25D expiration takes effect.
