You gave about as good a reply as anybody could. Who really knows? A mild drop and GNH may not even blink. But a repeat of the last severe drop like the sub-prime hangover and that is a different story.
You mention gold going out with the bath water. I sure did but there was a reason and the same thing would probably be repeated again. In that melt down a lot of investors needed cash to cover margin calls, even more, in my opinion rushed to save whatever capital they could from fear of loss of capital. Gold was one of the few sectors where some sort of capital could be raised, resutling in it being dragged down. So it was " the baby " going out with the bath water. I was really surprised when this happened because I was a believer that gold was a sure haven in troubled times. I've had to rethink that.
As for GNH, it would surprise me to see it drop that much, unless you think half is too much. I am very surprised how well the market has done during this Sep. - Oct. period. The phrase this time was different did apply. I see the market strength continuing into the feb. - March period. Then I will be taking a careful look, very careful.
