Asset Class Correlation Over 25 Years

How can you minimize the impact of a market crash on your portfolio? One main strategy is building a portfolio with asset classes that have low or negative correlation.

However, the correlation between asset classes can change depending on macroeconomic factors. In this Markets in a Minute from New York Life Investments, we show the correlation of select asset classes and how they have shifted over time.

What is Correlation?

Correlation measures how closely the price movement of two asset classes are related. For example, consider asset class A and B.

  • If asset class A rises 10% and asset class B also rises 10%, they have a perfect positive correlation of 1.
  • If asset class A rises 10% and asset class B doesn’t move at all, they have no correlation.
  • If asset class A drops 10% and asset class B rises 10%, they have a perfect negative correlation of -1.

When investors are building a portfolio, asset classes with negative correlation or no correlation are most desirable. This is because if one asset class drops during a market downturn, the other asset class will either rise or be unaffected.

Correlation Between Stock Categories

Stock categories have historically had some level of positive correlation. Here are the correlations for small and large cap stocks, as well as developed and emerging market stocks.

When macroeconomic conditions are strong, the correlation between stock categories tends to be lower as investors focus on individual company prospects. However, when market volatility rises, stocks tend to become more correlated as investors move to safer assets.

This was the case in 1998, when small and large cap stocks reached a peak correlation of 0.97. Russia defaulted on its debt, and a highly-leveraged hedge fund called Long Term Capital Management (LTCM) faced its own defaults as a result. Many banks and pension funds were invested in LTCM, and the Federal Reserve bailed out the fund to avoid a bigger crisis.

Shortly thereafter, small and large cap stock correlation reached a low in 2000. The dotcom bubble initially burst among large cap stocks, impacting some of the world’s largest companies. Small cap stocks didn’t see losses until 2002.

For developed and emerging markets, correlation peaked in 2010 when many countries were recovering from the global financial crisis. On the other end of the scale, correlation plummeted to its lowest level in 2017. One reason is that emerging markets became more distinct from one another due to their varying political risk and sector makeup.

Bonds, Commodities, and Currencies

In contrast to stock categories, there are some asset class pairings that have provided a low or negative correlation. Here is historical correlation data for U.S. stocks and bonds, as well as gold and the U.S. dollar.

Rolling 1-year correlations based on monthly returns.

Stocks and bonds generally have low correlation, with negative correlation in 14 of the last 25 years. Correlation tends to be highest during periods of high inflation expectations. On the flip side, correlation is typically lower during periods of low inflation expectations or high stock market volatility.

These factors contributed to negative correlation in 1998 during the Asian Financial Crisis. Stock prices flattened due to company trade relationships with Asian economies, while bonds benefited from lower rates and lower inflation. In 2002, high market volatility due to the dotcom bubble resulted in stocks and bonds reaching their most negative correlation.

Similarly, gold and the U.S. dollar generally move in opposite directions, with negative correlation in 23 of the last 25 years. When optimism in the U.S. economy is high, the U.S. dollar tends to rise. Conversely, when there are concerns about the U.S. economy or inflation, gold is considered a safe asset that holds its value.

In 2006, gold and the U.S. dollar reached their most negative correlation. As the beginnings of the subprime mortgage crisis appeared, investors piled into safe haven assets such as gold. In 2010, gold and the US dollar had a brief moment of positive correlation. Concerned about the European debt crisis, investors sought safe haven assets elsewhere, including both gold and the U.S. dollar.

Choosing Asset Classes

As investors think about which asset classes to include in their portfolios, it’s important to consider correlation. For instance, stock categories have historically been positively correlated. To diversify, investors may want to consider bonds and alternative assets such as gold.

In addition, macroeconomic events such as financial crises can have an impact on correlation, and investors may want to monitor these changes over time. Finally, considering the risk and return characteristics of various asset classes will allow investors to build a portfolio best suited to their needs.

What is the Success Rate of Actively Managed Funds?

For actively managed funds, the odds of beating the market over the long run are like finding a needle in a haystack.

Published

Actively Managed Funds

What is the Success Rate of Actively Managed Funds?

Over a 20-year period, 95% of large-cap actively managed funds have underperformed their benchmark.

The above graphic shows the performance of actively managed funds across a range of fund types, using data from S&P Global via Charlie Bilello.

Missing the Mark: Actively Managed Funds

Several factors present headwinds to actively managed funds.

  • Trading costs: First, fund managers will trade more often than passive funds. These in turn incur costs, impacting returns.
  • Cash holdings: Additionally, many of these funds hold a cash allocation of about 5% or more to capture market opportunities. Unlike active funds, their passive counterparts are often fully invested. Cash holdings can have the opposite effect than intended—dragging on overall returns.
  • Fees: Active funds can charge up to 1-2% in investment manager fees while funds that tracked an index passively charged just 0.12% on average in 2022. These additional costs add up over time.

Below, we show how active funds increasingly underperform against their benchmark over each time period.

Fund Type1 Year
% Underperformed
5 Year
% Underperformed
10 Year
% Underperformed
20 Year
% Underperformed
All Large-Cap 51879195
All Small-Cap 57718994
Large-Cap Growth 74869698
Large-Cap Value 59698587
Small-Cap Growth 80598597
Small-Cap Value 41819192
Real Estate 88627487

As we can see, 51% of all large-cap active mutual funds underperformed in a one-year period. That compares to 41% of small-cap value funds, which had the best chance of outperforming the benchmark annually. Also, an eye-opening 88% of real estate funds underperformed.

For context, Warren Buffett’s firm Berkshire Hathaway has beat the S&P 500 two-thirds of the time. Even the world’s top stock pickers have a hard time beating the market’s returns.

2020 Market Crash: A Case Study

How about active funds’ performance during a crisis?

While the case for actively managed funds is often stronger during a market downturn, a 2020 study shows how they continued to underperform the index.

Overall, 74% of over 3,600 active funds with $4.9 trillion in assets did worse than the S&P 500 during the 2020 market plunge.

Stage of 2020 CycleTime Period% Underperforming S&P 500
CrisisFeb 20 - Apr 30, 202074.2
CrashFeb 20 - Mar 23, 202063.5
RecoveryMar 24 - Apr 30, 202055.8
Pre-CrisisOct 1 2019 - Jan 31, 202067.1

Source: NBER

In better news, roughly half underperformed through the recovery, the best out of any market condition that was studied.

The Bigger Impact

Of course, some actively managed funds outperform.

Still, choosing the top funds year after year can be challenging. Also note that active fund managers typically only run a portfolio for four and a half years on average before someone new takes over, making it difficult to stick with a star manager for very long.

As lower returns accumulate over time, the impact of investing in active mutual funds can be striking. If an investor had a $100,000 portfolio and paid 2% in costs every year for 25 years, they would lose about $170,000 to fees if it earned 6% annually.

Ranked: The Largest Bond Markets in the World

The global bond market stands at $133 trillion in value. Here are the major players in bond markets worldwide.

The Largest Bond Markets in the World

The Largest Bond Markets in the World

In 2022, the global bond market totaled $133 trillion.

As one of the world’s largest capital markets, debt securities have grown sevenfold over the last 40 years. Fueling this growth are government and corporate debt sales across major economies and emerging markets. Over the last three years, China’s bond market has grown 13% annually.

Based on estimates from the Bank for International Statements, this graphic shows the largest bond markets in the world.

ℹ️ Total debt numbers here include both domestic and international debt securities in each particular country or region. BIS notes that international debt securities are issued outside the local market of the country where the borrower resides and cover eurobonds as well as foreign bonds, but exclude negotiable loans.

Ranked: The World’s Top Bond Markets

Valued at over $51 trillion, the U.S. has the largest bond market globally.

Government bonds made up the majority of its debt market, with over $26 trillion in securities outstanding. In 2022, the Federal government paid $534 billion in interest on this debt.

China is second, at 16% of the global total. Local commercial banks hold the greatest share of its outstanding bonds, while foreign ownership remains fairly low. Foreign interest in China’s bonds slowed in 2022 amid geopolitical tensions in Ukraine and lower yields.

Data as of Q3 2022.

As the above table shows, Japan has the third biggest debt market. Japan’s central bank owns a massive share of its government bonds. Central bank ownership hit a record 50% as it tweaked its yield curve control policy that was introduced in 2016. The policy was designed to help boost inflation and prevent interest rates from falling. As inflation began to rise in 2022 and bond investors began selling, it had to increase its yield to spur demand and liquidity. The adjustment sent shockwaves through financial markets.

In Europe, France is home to the largest bond market at $4.4 trillion in total debt, surpassing the United Kingdom by roughly $150 billion.

Banks: A Major Buyer in Bond Markets

Like central banks around the world, commercial banks are key players in bond markets.

In fact, commercial banks are among the top three buyers of U.S. government debt. This is because commercial banks will reinvest client deposits into interest-bearing securities. These often include U.S. Treasuries, which are highly liquid and one of the safest assets globally.

As we can see in the chart below, the banking sector often surpasses an economy’s total GDP.

Banking Sector

As interest rates have risen sharply since 2022, the price of bonds has been pushed down, given their inverse relationship. This has raised questions about what type of bonds banks hold.

In the U.S., commercial banks hold $4.2 trillion in Treasury bonds and other government securities. For large U.S. banks, these holdings account for almost 24% of assets on average. They make up an average 15% of assets for small banks in 2023. Since mid-2022, small banks have reduced their bond holdings due to interest rate increases.

As higher rates reverberate across the banking system and wider economy, it may expose further strains on global bond markets which have expanded rapidly in an era of dovish monetary policy and ultra-low interest rates.
