Have Synairgen's shares ever split?

Synairgen's shares were split on a 842:837 basis on 14 October 2020. So if you had owned 837 shares the day before before the split, the next day you'd have owned 842 shares. This wouldn't directly have changed the overall worth of your Synairgen shares – just the quantity. However, indirectly, the new 0.6% lower share price could have impacted the market appetite for Synairgen shares which in turn could have impacted Synairgen's share price.

Share price volatility

Over the last 12 months, Synairgen's shares have ranged in value from as little as 76.5p up to 197.9p. A popular way to gauge a stock's volatility is its "beta".

Beta is a measure of a share's volatility in relation to the market. The market (LSE average) beta is 1, while Synairgen's is -3.8841. This would suggest that Synairgen's shares have been inversely-correlated to the average (for this exchange) – so when the broader market trended up or down, Synairgen has bucked the trend.
