15 Best Biotech Penny Stocks to Invest in Right Now

In this article, we will be taking a look at the 15 Best Biotech Penny Stocks to Invest in Right Now.

Jared Holz, the healthcare strategist for Mizuho, spoke on CNBC’s “Closing Bell Overtime” in July on whether the biotech industry is ready for a breakthrough. Given that there are hundreds of publicly traded stocks that don’t amount to anything overall, he said that the biotech industry has been a “super tough sector” in any case. He went on to say that it is difficult to make an industrial decision because there are many advantages and disadvantages.

But after “indiscriminately trading horribly for so long,” Holz said he thinks the sector is trading “a little bit better” now that it has stopped declining daily.

He reasoned that it is time for a move higher because all the disadvantages, such as pricing pressures and competition in the quantity of assets in the publicly listed arena, are now fully recognized and absorbed. “It would definitely be a less negative move, even though it might not be a huge one,” Holz said.

With these trends in view, let’s look at the best biotech penny stocks to invest in right now.
