For example, in 2012, Banro issued an PR for an event in Goma that had an negative effect on the stock price.
“Banro's operations are located some 200 kilometres southwest of Goma and have not been affected by this disruption in any manner; however the media attention has clearly created concern amongst investors and impacted negatively on the share price. Banro has a number of alternative supply routes should the current borders be affected, which is not the case at present.”
Of course, yesterday’s event is not as daunting as the event in 2012, but my point is, events happening in the same region that receive international exposure can have an effect on the price.
