60/40 wallet out. The 50/30/20 portfolio plus AI investing exists.

For decades, a 60/40 portfolio — 60% stocks and 40% bonds — has been considered the gold standard for balanced investing. The goal was to combine the long-term growth potential of stocks with the overall stability of bonds. But according to Jose Minaya, global head of investments and wealth at the Bank of New York, this approach may no longer be appropriate for today’s complex markets.

“The old diversification is… 60/40 stocks and bonds… [but] “Markets are more complex and complex,” Minaya said on the Bloomberg Masters in Business programme.

Today’s markets are shaped by higher inflation and greater market volatility than was prevalent when the 60/40 rule became popular, Minaya said. He said the solution lies in a more flexible 50/30/20 split between stocks, bonds and alternative assets, arguing that greater diversification is now necessary.

In today’s market, alternative investments and artificial intelligence must be taken into account when building a well-balanced portfolio, Minaya said.

Why a 60/40 portfolio is no longer enough

The 60/40 model has historically relied on a low correlation between stocks and bonds—when one goes down, the other often goes up. However, in 2022, a well-diversified portfolio of 60% stocks and 40% bonds declined by about 16%. Rising inflation, tightening monetary policy and geopolitical pressures have changed how markets move, meaning investors need exposure beyond traditional assets to navigate this new environment, Minaya said.

With diversification, there is more complexity in helping clients build their portfolios: “There’s more sophistication in terms of how you package solutions, you know.” “More sophistication now in terms of the need to have alternatives…for customers.”

Inside the 50/30/20 model

With the 50/30/20 investment strategy, an investor divides his portfolio across three broad asset classes:

• 50% of equity (stocks, either individually or in funds) for growth potential
• 30% bonds (fixed income securities, alone or in funds) provide income and stability through interest payments
• 20% alternatives (individually or in funds) to provide diversification and uncorrelated returns (this can include commodities, hedge funds, private equity and real estate)

This structure seeks to maintain the upside of equity markets while adding buffers and new sources of return through bonds and alternative strategies.

Potential benefits and trade-offs

Adding alternatives is not without its challenges. Many of these assets, such as real estate and commodities, are illiquid, come with higher fees, and require longer holding periods to see a return.

For ordinary investors, access to alternatives has been expanded through interval funds (or closed-end funds), but they also carry a level of illiquidity and often involve fees, among other potential drawbacks.

On the other hand, alternative investments can help investors weather recessions and market shocks.

How artificial intelligence is changing the future of portfolio management

Minaya said he sees artificial intelligence (AI) as a powerful ally in the next era of investment. It is believed that it can help investors make decisions. He also believes that investors can find AI-oriented businesses worth investing in. AI has transformative potential because it can “review a lot of information…and disseminate that information,” he said.

There is no doubt that artificial intelligence is changing the future of portfolio management and the way the world works. However, Minaya also explained that a combination of humans with AI is better than just AI alone: ​​“Humans with AI are going to be better than humans without AI,… You will still need the component… [of] “Humans… are in the mix.”

Bottom line

Minaya’s message is clear: investors can no longer rely on old formulas. The 60/40 portfolio may have been successful for decades, but today’s world requires greater diversification and smarter tools.

The 50/30/20 framework – supported by advances in artificial intelligence – reflects the shift towards investment portfolios designed for complexity, not simplicity. In an uncertain market, patience and innovation can be the new pillars of successful investing.
