Come to think of it, that's the key question that we keep asking and really belongs up at the top only I haven't a clue as for any good answers. We started hashing it out on this thread when certain drug stocks soared (and loony left press called 'em "greedy"(As Ebola spreads, drug stocks surge) and then airline stocks tanked (Airlines Stocks Are Getting Crushed And Traders Are Blaming Ebola), and then the patient died (Drug Stock Tanks After Ebola Patient Treated With Its Drug Dies (Note timing)) and then almost daily we hear from the pundits: Face Mask And Hazmat Stocks Are Crashing, Global stocks down on recovery, Ebola worries.
My take is we got a lot more opinions than facts, so in the short term (personally) I'm ignoring it except for the fact that the longer term sure does look bleake...
My recommendation is to invest in knee brace manufacturers. When we get done with our collective knee jerks over ebola they will be in demand.
