So what
On April 24, ShockWave stock jumped 10.2% after the company announced that it would release first-quarter 2019 results on May 8. (Yes, today.) Shares continued to rise for the next couple of trading days.
The company didn't release any other notable news at about the time its stock got a nice boost, nor does it appear to have been the subject of any market-moving news. Thus, it seems the setting of the earnings release date was the primary catalyst for ShockWave stock's strong April performance. This announcement likely led more investors to discover the stock, as the company has only been publicly traded since early March.
