Note that that it meaning cannot distinguish between loss and you can get. Generally speaking, private dealers consider exposure due to the fact chance one its investment you may generate losses. [2] He is apt to be pleased with an investment get back that’s more than requested – a great “self-confident shock.” But not, as high-risk property make negative surprises together with confident of those, identifying risk since the uncertainty of the rate of get back was reasonable. Better suspicion results in greater likelihood your resource can establish large development, in addition to greater chances that resource can establish huge loss (temporarily) plus in highest or down obtained worth (in the long term.)
