David Sraer教授是一位在金融领域具有深厚学术背景和丰富教学经验的学者。他在法国图卢兹经济学院(TSE)攻读经济学博士学位,师从John Ciao教授。完成博士学位后,Sraer教授前往美国,在普林斯顿大学经济系担任教授数年。自2014年起,他一直在加州大学伯克利分校(UC Berkeley)工作,主要研究领域包括公司金融和行为金融学。

在行为金融学领域,Sraer教授的研究兴趣主要集中在两个方面:一是更好地理解散户投资者的投资决策;二是探讨投资者在金融市场中的共识如何可能导致市场价格的效率低下。

Sraer教授在伯克利哈斯商学院担任金融系主任,同时在DAFI-Berkeley联合项目中担任《行为金融学》课程的授课教师。在这里,他将他的专业知识和研究成果传授给学生,为他们的学术和职业发展提供支持。通过这门课程,学生们不仅能够深入了解行为金融学的理论和实践,还能接触到国际前沿的学术思想和研究方法,为他们未来的学术或职业道路打下坚实的基础。

最近,我们与David展开了一次对话,在这次对话的最后,他提出了自己对金融学生的真诚建议:不要把金融当作简单的公式来学习,需要理解更宏大的图景,要理解世界。

教授演讲译文:

我认为我想给那些想要从事金融职业的学生的主要建议是,要理解金融不仅仅是一个公式。金融不仅仅是数字和计算;它是一种理解我们周围世界的方式。

这是很多人在量化金融中教过的,这再次回到了我之前所说的:资产的定价就是对其基本面定价的方式。在这种框架下,我们可以非常数学化地思考问题,比如有一个基础资产的扩散过程,比如股息,然后我们可以思考如何定价,这取决于我们心中所想的模型。

但我认为这不是金融市场的全貌。如果你想要成为一名优秀的金融专业人士,你必须理解你定价的证券。如果你要定价股票,你必须了解股票背后的公司。你必须本质上是一个经济学家;你必须理解是什么推动了公司的利润,公司如何在其战略环境中发展。

然后你还想思考宏观经济,你想思考利率、价格、增长、创新——所有这些都将影响你对金融市场的看法。有时,学生们倾向于忘记这一点,他们倾向于认为,“嗯,我可以把所有金融市场总结为一个黑箱公式或者某种定价公式。”

所以,我认为一个重要的建议是保持对世界的好奇心,像经济学家一样思考,了解新闻,思考更为全球的大局。如果你这样做,你会相比那些狭隘的量化分析师拥有一个非常重要的优势,他们只知道,“我知道一个定价公式,让我来应用它,却没有真正理解我在做什么。”



David Sraer:

I think the main advice that I like to give students who want to pursue a career in finance is really to understand that finance is not just a formula. It's about understanding that finance is more than just numbers and calculations; it's a way to comprehend the world around us.

So a lot of what people teach in quantitative finance goes back to what I was saying before: the pricing of an asset is just the pricing of its fundamentals. We can think about things in very mathematical terms, like a diffusion process for the underlying, you know, dividends, and then we can sort of think about how to price this depending on the model we have in mind.

But I think this is not the full picture of financial markets. If you want to be a good finance professional, you have to understand the securities you're pricing. If you're going to price stocks, you have to understand what is the company that underlies the stocks. At heart, you have to be an economist; you have to understand what's driving the profit of the company, how does the company evolve in its strategic environment.

Then you want to think also about the macroeconomy, you want to think about interest rates, prices, growth, innovation—all the things that are going to matter for forming your opinion about how to think about financial markets. And sometimes students tend to forget that and they tend to think, ‘Well, I can just summarize all financial markets into a black box formula or some pricing formula.’

So, I think a big advice is to keep being curious about the world, keep thinking like an economist, read the newspapers, think about the global picture. I think this is a really important edge you will get if you do that as opposed to being sort of a more narrow-minded quant who just thinks, ‘I know one pricing formula, let me apply it without really understanding what I'm doing.’
