Penny stocks are often high-risk investments that can be illiquid and difficult to sell.

If you're invested in penny stocks, it's important to be aware of the risks.

Cellectar Biosciences has been on a downward trend since its peak in February 2021.

IsoRay  has been struggling financially and has been forced to sell assets.

QuantumScape is a high-flying stock that has been hit hard by recent news that its technology may not be as promising as originally thought.

If you're invested in any of these penny stocks, I recommend selling them before it's too late.

The stock market is a volatile place, and penny stocks are even more so.

Only invest money that you can afford to lose.
