AI enthusiasm remains far below dot-com extremes

The AI-led bull market has been more measured than the dot-com boom, while forward valuations remain less than half their March 2000 peak.
Digit 3

Heavy bond buying has not been bearish for stocks

Welcome to the September 2026 edition of Blackrock's Student of the Market.

0:07
This month, we'll look at the market that has continued to reward investors, but where the story beneath the headline is becoming more nuanced.

0:16
We'll start with U.S.

0:17
stocks and the historical patterns around midterm election years, then compare today's AI rally with the.com.

0:26
From there, we'll examine how benchmark construction is shaping emerging market results.

0:32
We'll finish with investor flows, the changing relationship between cash and bonds, flexible income strategies, and the potential role of alternatives.

0:42
As always, the goal is not to predict the next market move.

0:47
It is to use history and current data to put today's market environment into perspective.

0:53
Let's begin on slide three.

0:55
U.S. stocks have had an unusually strong start to the midterm election year.

1:00
Through August, the market was up 13.14%, making 2026 the six best first eight months of a midterm election year in this nearly 100 year history.

1:14
The left side provides important context.

1:17
Across all midterm election years, the average return during the first eight months was only 1.62%, while the average return during the final four months average 5.56%.

1:31
The table on the right narrows down the analysis to the 10 strongest starts.

1:36
Those years gained 15.49% on average through August and another 5.7% over the final four months.

1:46
The outcomes are not uniformly positive as 19861978, 2018 all declined from September through December.

1:56
The takeaways?

1:56
That strong momentum has often continued, but history provides context, not a forecast.

2:03
Moving ahead on the next slide, the next question is whether September's reputation should change the outlook.

2:10
Historically, September has been the weakest month for U.S.

2:13
stocks with an average return of 0.78%, negative 0.78%.

2:21
The pattern is slightly worse in midterm election years, when September averaged a -1 point O 9%.

2:28
That seasonal weakness is real in the historical data, but it's only one month within a broader pattern.

2:35
In midterm election years, the average returns for October, November, December were two point 452.80 and 1.17% respectively.

2:46
So the historical message is not simply that September is weak, it is that difficult.

2:51
September has often been followed by a stronger fourth quarter.

2:55
Investors should avoid using seasonality as a market timing tool, but it can help set expectations for periods of normal volatility following a strong year to date rally.

3:06
If markets experience weakness in September, it may present a reasonable opportunity for long term investors to put cash to work.

3:13
Next, we look at technology leading the market.

3:17
Comparisons with the dot com bubble are understandable.

3:20
The data, however, shows that the the magnitude is very different so far.

3:25
On the left, the technology sector's cumulative rise following the launch of ChatGPT remains remains well below the advance that followed the Netscape IPO.

3:37
On the right, the contrast is more specific.

3:39
Technology gained 360% over the three years ending in March 2000, compared with 127% over the last three years ending in August of 2026.

3:55
Those numbers are cumulative.

3:57
Valuations also differ sharply.

4:00
The sector traded at 55 times forwardearnings@the.com peak versus technology trading at 21 times earnings today.

4:11
This does not mean technology is inexpensive or immune to a correction.

4:16
It means the current AI driven rally has been more measured in both performance and valuation than the late 1990s experience.

4:26
Switching gears to emerging market stocks, they're a great example of why benchmarks matter.

4:32
Through August, the MSCI Emerging Markets Index returned to over 24% compared to 12.7% for the FTSE Emerging Index.

4:43
The main reason is South Korea represents 20 percent, 20.85% of the MSCI Emerging Markets Index, but it's not included in the FTSE Emerging Market Index.

4:55
That different also changes the sector mix technology over 40% in the MSCI Index versus over 31% for the FTSE Index.

5:05
The country weights of China, Taiwan, and India also differ meaningfully.

5:11
Even valuation comparisons are affected.

5:14
The MSCI index as a trailing PE less than 12 compared with 15 for the FTSE index.

5:23
The practical take away is that 2 funds labeled emerging markets can produce very different results because they may own different countries, sectors, and companies.

5:32
Benchmark selection and investment decision, not in administrative detail.

5:39
Moving on to bond fund flows and future market performance, investor behavior remains much more cautious than the stock market performance might select.

5:49
Over the last 12 months, bond funds, both bond fund mutual funds and ETFs, took in more than $466 billion more than stock funds.

6:01
The chart on the left shows that this is a large gap, although not unprecedented.

6:06
The chart on the right asks that what happened after similar extremes.

6:10
When bond funds flows exceeded stock fund flows by more than $200 billion, U.S.

6:17
stock returned on average 19.1% over the following year, while US bonds returned only two point O 7%.

6:27
When stock fund flows led by more than $200 billion, stocks returned only 5.33% and bonds returned earned 5.58% on average.

6:39
This is not a market timing signal and and the current outcome may differ, but historically heavy demand for bonds has often reflected caution rather than an end to an equity advance.

6:52
Strong bond flows can coexist with favorable subsequent stock returns.

6:59
Building on that, looking at money fund flows, slowing the composition of defensive flows is also changing.

7:06
Money market funds received $1.149 trillion in 2020, three $949 billion in 2020, four 886 billion in 2025, but nog in 2026.

7:22
Through August, that figure is only 213 billion.

7:26
Bond funds, by contrast, received $575 billion through July of 2026.

7:33
The annualized pay shows here is about 320 billion for money funds and 986 billion for bond funds.

7:41
One possible driver is a change in the Treasury curve.

7:45
At the end of 2023, the three months Treasury yield yielded around 5.4%, well above the 10 year Treasury yield of 3.88%.

7:55
By August of 2026, that relationship has reversed.

8:00
The 10 year Treasury yielded 4.75% and the three month Treasury yielded 3.91.

8:08
As longer term yields become more competitive, investors had more incentive to consider bonds rather than remain entirely in cash.

8:17
The relationship is historical and correlated, not necessarily casual.

8:22
The fixed income challenge has not simply been the level of rates, it's also been the size and frequency of of the swing.

8:29
Since the 10 year Treasury first moved past 4% in October 2022, yields have repeatedly moved between roughly the low 3% range and the high 4% range.

8:42
This table shows how different bond approaches perform during each move.

8:47
In the rising rate period from April to October 2023, core bonds lost 7.29% while multi sector bonds lost only 2.12% and non traditional bonds gained 0.22%.

9:02
The latest period from October 2025 through August 2026, multi sector and non traditional bonds gained 2.28% and 2.18%, while the core bond index declined to 0.54%.

9:19
Across the full.

9:20
Annualized returns were 6.91% for multi sector bonds, 5.73% for non traditional bonds and 4.71% for core bonds and 4.22% for money market funds.

9:35
Although active strategies carry their own risk and outcomes can vary, flexibility has historically been rewarded.

9:43
Active flexible fixed income strategies have outperformed the index across the entire period examined.

9:50
Let's finish with the diversification challenge that has changed in the current decade.

9:55
From 2020 through August 2026, the maximum drawdown was 23.87 for U.S.

10:01
stocks and 17.18% for US bonds.

10:05
At the same time, the correlation between stocks and bonds rose to 0.51, meaning bonds provided less diversification than investors experienced the prior 2 decades.

10:17
The equity market neutral category shown here had a maximum drawdown of 5.2%, volatility of 3.25, and stock correlation of 0.02 over that same.

10:30
The combination illustrates the potential value of a return stream that is less dependent on the direction of traditional markets.

10:39
This this slide uses equity market neutral as one example, not as a proxy for every alternative strategy.

10:46
The broader take away is that when stock and bond diversification is less reliable, carefully selected alternatives may help manage drawdowns and portfolio risk.

10:58
In summary, in closing, this month's BlackRock Student of the Market shows that strong markets can coexist with cautious investing positioning.

11:07
U.S. stocks have entered September with strong momentum.

11:10
Today's technology rally remains more measuredthanthe.com bubble and defensive flows are shifting from cash towards bonds as longer term yields become more competitive.

11:21
The takeaways?

11:22
To remain invested, selective and diversified, investors should look beyond short term season, understand the exposures behind their investment, consider flexibility within fixed income, and evaluate alternatives where appropriate.

11:37
The goal is not to predict the next market move, but to build a portfolio that can seed across a range of outcomes.

11:44
Thanks for listening.

11:45
We'll see you next month on Blackrock's Student of the Market.

Investment insights to help guide client conversations

Key chart from seminar

Morningstar and Bloomberg as of 6/30/26. U.S. stocks represented by the S&P 500 Index. AI companies were identified using an objective holdings-based screen: S&P 500 constituents were classified as ‘AI’ if, as of June 30th, 2026, they were held in at least one of the five largest (by AUM) U.S.-listed AI-themed ETFs, selected based on stated AI-focused investment objectives/strategy. The resulting AI basket includes 51 S&P 500 companies. Energy represents S&P 500 companies in the GICS Energy Sector. Everything Else represents the S&P 500 excluding the AI-classified and Energy constituents. ETF selection and constituent classification are rules-based and do not reflect BlackRock’s view of any company’s current or future AI revenue, business exposure, or prospects. Index performance is for illustrative purposes only. Index performance does not reflect any management fees or expenses. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not guarantee future results.

AI continues to lead markets

Markets benefit from easing geopolitical tensions, accelerating AI investment and hardware shortages. We remain constructive on AI equities as a driver of U.S. earnings growth.

Diversify portfolios for volatility

Strong rallies can bring elevated volatility. Diversify with buffer strategies seeking to help reduce downside risk and alternatives to add differentiated sources of potential return.

Higher yields can create income opportunities

A hawkish Fed has kept bond yields elevated. Today's higher yields can continue to create attractive income opportunities for fixed income investors.
