Penny stocks: the casino chips of Wall Street. While the suits play with blue chips, these under-$5 wildcards keep traders glued to their screens. Here’s what’s heating up as we close out June.

### The Contenders: High-Risk, High-Reward Plays

Volatility’s the name of the game—these tickers swing harder than a crypto meme coin during an Elon tweet storm. Perfect for traders who think ‘diamond hands’ applies to pink sheets.

### Why Today Matters

June 26 marks quarterly rebalancing—when hedge funds dump losers and prop up winners. That means fireworks for micro-caps. Just don’t confuse momentum with actual fundamentals (we’ve all been burned before).

### The Bottom Line

Penny stocks are liquidity grenades—pull the pin at your own risk. But for those chasing asymmetric upside? Today’s your playground. Remember: the house always wins… unless you cash out before the music stops.

(SRFM) – Surf Air Mobility is an electric aviation, software, and air travel company. SRFM had a Dollar Volume of $234.94 million on Wednesday, while its stock price plunged by 29.4%.

SRFM stock initially rallied on news that big data company Palantir Technologies (PLTR) bought 1,040,557 shares, giving it a 19.9% stake in Surf Air Mobility. However, shares later declined after the company announced it has entered into definitive agreements for the purchase and sale of 10,800,002 shares of common stock and pre-funded warrants. SRFM expects to earn gross proceeds of $27 million from the share sale.

(PSTV) – Plus Therapeutics is a clinical-stage pharmaceutical company focused on developing targeted radiotherapies for adults and children battling rare and difficult-to-treat cancers. On June 25, PSTV had a Dollar Volume of $229.54 million, accompanied by a stock price surge of 68.5%. Shares are also trending higher in pre-market trading at the time of writing.

Shares jumped on news that the company’s lead drug candidate, REYOBIQ, had received the U.S. FDA clearance for its Investigational New Drug (IND) application. REYOBIQ is being tested for the treatment of pediatric patients with supratentorial recurrent, refractory, or progressive high-grade glioma (HGG) and ependymoma. The company will now start conducting clinical trials, with the U.S. Department of Defense providing a $3 million grant to fund the study.

(ICU) – SeaStar Medical Holding is a commercial-stage healthcare company focused on developing novel treatments for critically ill patients facing organ failure and potential loss of life. Yesterday, ICU stock had a Dollar Volume of $116.98 million, while its stock price surged by 17.6%.

The company announced that it has undertaken a series of steps to regain compliance with Nasdaq’s continued listing requirements after receiving a warning letter in June 2024. The company was granted an extension until June 22, 2025, to comply with the alternative requirement of $2.5 million in stockholders’ equity, since it was unable to maintain a minimum market capitalization of $35 million. Accordingly, ICU completed a $4 million public offering of common stocks and warrants. It also entered into a purchase agreement with Lincoln Park Capital to purchase up to $15 million of ICU’s common stock over a three-year period. Moreover, ICU took measures to increase its customer base and boost revenue, as well as reduce operating expenses and lower its debt.
