...markets may not be as much negatively impacted by an event if the event does not lead to adverse economic outlook having negative bearing on earnings.

By Lance Roberts “Yes, there were a few periods that led to more disastrous outcomes, such as the Yom Kippur War, the oil embargo, the USS Cole bombing, 9/11, and the London Subway bombing. However, those events coincided with the bursting of the “Nifty-50” bubble, the “Dot.com” bubble, and the “Financial Crisis.” While there is undoubtedly a risk that the current Iran-Israel conflict could spiral into something larger, history suggests those odds are relatively low and that over the next 12 months, any near-term impact will likely produce investment opportunities.”
