# Why Is Avidity Biosciences Stock (RNA) Down Today?

Avidity Biosciences (RNA) stock appeared to plummet on Friday after the RNA-focused biopharmaceutical company's shareholders voted to approve a merger with Novartis (NVS).

The decision to complete the merger with Novartis has resulted in chaos for RNA stock this morning. The company had to reconvene a special shareholder meeting earlier this week to prepare for the deal. That included giving the company enough time to distribute issued and outstanding shares of Atrium Therapeutics.

Additionally, the timing of the merger is causing confusion this morning, as the merger went into effect today. This should see Avidity Biosciences stock removed from the public market and replaced with Atrium Therapeutics. As such, investors can expect volatility until the full effects of the merger are reflected on public markets.

## **Avidity Biosciences Stock Movement Today**

As noted, it's unclear if Avidity Biosciences stock is actually down today, or if public listings haven't caught up to the merger agreement with Novartis. As such, traders will want to be careful about making any moves with the company's stock until this is all sorted out.
