We are facing extreme volatility.

Alan White and I spent the next two or three years working together on this. We developed what is known a stochastic volatility model. This is a model where the volatility as well as the underlying asset price moves around in an unpredictable way.

I don't enjoy any kind of danger or volatility. I don't have that kind of 'I love the bad guys' thing. No, no thank you. I like nice people.

Global warming creates volatility. I feel it when I'm flying. The storms are more volatile. We are paying the price in more hurricanes and tornadoes.

Now quantitatively we rank things on something called alpha over standard deviation, which is the return independent of the market divided by volatility. Usually, to get a high ranking, you need some buying pressure.

In my view, the biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital. Not only is the mere drop in stock prices not risk, but it is an opportunity. Where else do you look for cheap stocks?

Once you get a reputation for emotional volatility, it can take years of model behavior to change how others see you.

We will not allow our country ever to be at the mercy of commodity price volatility or external markets.

There is little room for complacency, and it is important to guard against sporadic volatility in financial markets.

Look, I think if you've got a niche portfolio or just operating in one country, like the United States, your ability to absorb the volatility is much less.

The lack of a consistent policy from major economies is the main source of volatility.

Efforts to promote financial stability through adjustments in interest rates would increase the volatility of inflation and employment. As a result, I believe a macro-prudential approach to supervision and regulation needs to play the primary role.

In a global marketplace with its increased insecurities and - indeed often - volatility and instability, national economic stability is at a premium, the precondition for all we can achieve, and no nation can secure the high levels of sustainable investment it needs without both monetary and fiscal stability together.

Asset managers have different approaches, and I don't wish to suggest there is only one way to run money. There are many ways one can attempt to reduce risk, improve performance, lower drawdowns and reduce volatility.

What's interesting is that you can have a set that's very calm, very smooth, very cooperative... and end up with a terrible movie. And you can have a set that's really horrible as far as relationships and volatility, and come up with a great movie. Sometimes that energy gets infused into what ends up on film - it's interesting in that way.

Investors have few spare tires left. Think of the image of a car on a bumpy road to an uncertain destination that has already used up its spare tire. The cash reserves of people have been eaten up by the recent market volatility.

Volatility may be rising simply because investors must digest more information every day.

It's about surrendering to this feeling of utter fragility, and singing through the volatility of it all. The earth is unstable, and I'm part of the earth. I can feel it coursing through my own body. I feel the energy of everything, flickering. Let's just sing together.

By promising to intervene in vulnerable markets in the event of excessive financial volatility, the IMF, as the largest player, would reduce coordination problems among investors.

Never think that lack of variability is stability. Don't confuse lack of volatility with stability, ever.
