Have Marinus Pharmaceuticals's shares ever split?

Marinus Pharmaceuticals's shares were split on a 1:4 basis on 22 September 2020. So if you had owned 4 shares the day before before the split, the next day you'd have owned 1 share. This wouldn't directly have changed the overall worth of your Marinus Pharmaceuticals shares – just the quantity. However, indirectly, the new 300% higher share price could have impacted the market appetite for Marinus Pharmaceuticals shares which in turn could have impacted Marinus Pharmaceuticals's share price.

Marinus Pharmaceuticals share price volatility

Over the last 12 months, Marinus Pharmaceuticals's shares have ranged in value from as little as $1.05 up to $11.26. A popular way to gauge a stock's volatility is its "beta".

MRNS.US volatility(beta: 1.13)Avg. volatility(beta: 1.00)LowHigh

Beta is a measure of a share's volatility in relation to the market. The market (NASDAQ average) beta is 1, while Marinus Pharmaceuticals's is 1.125. This would suggest that Marinus Pharmaceuticals's shares are a little bit more volatile than the average for this exchange and represent, relatively-speaking, a slightly higher risk (but potentially also market-beating returns).
