People are getting tired of being constantly on edge. Maybe that means they do let down their guard or that they're complacent. What does it take to shake that? A 5% correction? A 10% one? Those kinds of declines are unfortunately something you put up with.

The fact that the bond market is rallying today is a plus. If this ends up being a bear market, it will be one of the first ever that began when interest rates are down.

What caused 2008, in my opinion, is that people just didn't see the risk. These people that took on all this risk didn't think they had it - they thought they hedged it all away. As long as there's a perception of risk, and a culture of looking for risk, it's going to be hard to deflate us.

Be flexible. Don't be afraid to change your mind. If you're wrong, change your mind. If you go down the wrong path, and you're down 10-12%, it's better to sell down 15% versus 50%. If you have an idea that something is going to happen, you're predicting the future, and it's OK to be wrong. Where you can go wrong is by making a prediction that doesn't come true, and then sticking with it.

There's an old line that goes, the truck you see 400 yards down the road is not the truck that hits you. When we see these problems coming, they usually get defused. Brexit may have been a surprise, but we recognized it as something that could possibly happen.

I think people are complacent. But complacency is like any other metric. It's easy to measure where it is, but it's hard to tell how persistent it is. What causes really big bear markets is not just when people are overly complacent - it's when that complacency is sticky. As long as the skepticism can refresh itself, I think that the markets are still quite viable.
