Wall Street titans like David Kostin, Rick Rieder, Mike Wilson, and Rob Arnott tell BI their best career advice

Takeaway: Prioritize going to the office

"Show up in the office," Kostin said. "I can't imagine how a young person is going to actually absorb all the dimensionality of what's happening in the client relationships and with their work and colleagues and not be in the office."

Kostin's advice is simple, but it comes at a time when a massive debate is raging about various companies' RTO policies. In Kostin's view, working in person is critical to developing your career early on.

Takeaway: Bet on yourself, and be OK with being wrong

"You've got to be willing to go take a stand on stuff, whether it's in a meeting, with people you report to, pointing out things that you don't agree with, kind of making a firm stance," Wilson said.

Wilson says this boils down to being open to taking on "personal risk," or the chance that the argument you're making could be wrong — or right.

"On Wall Street, personal risk often means taking contrarian views because that's where the real money is made and accepting the idea that you're going to be wrong along the way. I think ultimately how you deal with those consequences will determine whether you're successful or not," he added.

Takeaway: Understand how technology is trending

As the biggest firms in the world pour money into AI development, Rieder said that those who are early in their careers should think about how the economy might look in the years ahead as robotics and AI increasingly augment our lives.

"I think the world's changing faster than anybody really recognizes," Rieder, who oversees $3 trillion, said.

"For young people today, understand where that's going to happen and how you take advantage of that — I think it's a really, really big deal," he continued. "I think we've left status quo, and we're moving to a whole new era."

Takeaway: Be curious despite consensus, and come to a conclusion only after stress-testing it

"Constantly being curious, even if there might not be an obvious payoff to it," Wong, who previously worked at the Federal Reserve, said for her first piece of advice. "If investing is about finding what the market has not priced in, then what people have not priced in usually are in the details. For me, I have learned to be attuned to that little voice inside my head that sounds a tiny alarm in cases where I am about to make some broad assumptions."

Second, when it comes to forecasting, Wong said to consider if a conclusion is still valid after considering multiple arguments and points of view.

"The way I decide on whether to make an out-of-consensus call is to see whether it's possible to arrive at a forecast in many different ways," she said. "Most times I take as the forecast the middle of those ways — and that could at times be totally out of consensus, and at times be smack in the middle of consensus."

One of Wong's current out-of-consensus calls is that there's a 60% chance the US economy is headed toward or already in a recession.

Takeaway: Treat every job as a learning opportunity, even if it's not what you see yourself doing long-term

Landing your dream job at the very start of your professional life is a rare occurrence. More often than not, you may find yourself at a job that isn't a great fit or isn't aligned with your long-term goals.

However, there's a lot to be learned while figuring out your career. "Do your hardest at the job you're currently at, even if it's not the job you love," Feroli said. "Whatever you're doing now will help you get to where you want to be."

Takeaway: Enjoy what you do, and challenge widely accepted beliefs

"First piece of advice: Do what you love," Arnott said. "Because if you don't do what you love, you probably won't be very good at it. And if you do what you love, you're going to have fun even if you're not wildly successful."

He continued: "Second: Never accept conventional wisdom as true. Always be curious. I've made a career out of listening to conventional wisdom and thinking, 'Gosh, has anyone tested that?' And I go and test it, and half the time it turns out to be true — and fine — and half the time it turns out to be a myth."

Invesco, PIMCO, and Charles Schwab all use Arnott's alternative indexes as the bases of various mutual funds and ETFs they offer. Arnott recently told BI that market consensus around AI could be too bullish, and large-cap growth stocks may be in for a rough patch.

Takeaway: Take time to explore interests outside of work

It may seem counterintuitive, but the key to Li's career success has been making time for new experiences outside work.

"Don't only spend time on the things immediately useful to you in your seat right now," Li said. "The world is so unpredictable. Other things you could absorb may end up being helpful to you in ways that you don't even know."

Hobbies that she's picked up over the years, such as learning about cryptocurrency or studying Italian, have opened doors in her life that she could not have foreseen.

Li believes having diverse experiences is especially important in a post-AI world: "These days, I really force myself to experience things that have nothing to do with my job because it trains my brain in ways that my job doesn't. Who knows, it could become useful in the future and in an environment where we just don't know where the future is," she said.
