We recently published an article titled Massive Sell-Offs Just Hit These 10 Stocks Today. In this article, we are going to take a look at where Halozyme Therapeutics, Inc. (NASDAQ:HALO) stands against the other stocks.

Wall Street’s main indices finished mixed on Tuesday, as investors digested the country’s latest inflation figures, which came out lower than expected.

On Tuesday, the Labor Department reported that the Consumer Price Index for April rose by only 0.2 percent last month, bringing the annual inflation rate to 2.3 percent, versus the 2.4 percent in March. It was the lowest annual rate since February 2021.

Only the S&P 500 and the tech-heavy Nasdaq registered gains among all major indices, up by 0.72 percent and 1.61 percent, respectively. The Dow Jones, on the other hand, was down by 0.64 percent.

Beyond the main indices, 10 firms lagged in performance amid negative news, sparking sell-offs.

To come up with the list, we considered only the stocks with a $2-billion market capitalization and $5-million trading volume.

Halozyme Therapeutics, Inc. (NASDAQ:HALO)

Halozyme Therapeutics, Inc. (NASDAQ:HALO) nosedived by 24.56 percent on Tuesday to close at $50.23 apiece as investor sentiment was weighed down by news that the Centers for Medicare and Medicaid Services is set to negotiate prices of several high-cost drugs each year.

Biologic drugs usually have 13 years on the market before the CMS will consider them for price negotiations, but such does not seem to be the case for drugs that contain hyaluronidase or enzymes degrading a key component in the body's connective tissues.

Halozyme Therapeutics, Inc. (NASDAQ:HALO), a biopharmaceutical company focusing on developing novel recombinant human enzymes, could be impacted by the pricing negotiations initiative.

Following the news, Leerink Partners downgraded the company’s stock to underperform, while also lowering its price target to $47 from $63 previously.
