The Market Is Doing Something It's Only Done Once Before. Here's What History Says Happens Next.
The S&P 500 is up 14% year to date, and if this year is anything like previous years, it will end 2026 even higher. This would be the fourth year in a row with double-digit gains, which hasn't happened since the late 1990s.
Intelligence analysis by Llama

The market has enjoyed a strong bull run over the past three and a half years, doubling since the beginning of 2023. The gains have been driven by artificial intelligence (AI), which didn't exist as an industry before 2023. Companies like Amazon and Alphabet are planning to spend about $700 billion this year, and that will increase to $1 trillion next year.
Imagine you're on a rollercoaster that's been going up for a long time. It's like the market has been going up for three and a half years, doubling since the beginning of 2023. But just like how rollercoasters can go down, the market can also go down. It's like the market is playing a game of 'up and down' and we need to be prepared for both.
Analysis
The CAPE Ratio and Market Valuations
The cyclically adjusted price-to-earnings ratio, or CAPE ratio, has surpassed 40 only one other time -- in January 1999, the fifth year of double-digit market gains. This metric, which adjusts the price-to-earnings ratio for inflationary impact, is seen as a more reliable valuation metric for the market than the average P/E ratio for the 500 stocks in the index. Today, it's nearly 41 after surpassing the 40 mark in May.
A Similarity to the Dot-Com Bubble
The market has enjoyed a strong bull run over the past three and a half years, doubling since the beginning of 2023. The gains have been driven by artificial intelligence (AI), which didn't exist as an industry before 2023. Over the past three years, the category has grown by leaps and bounds, and the large companies that are leading the charge continue to invest billions in developing their platforms. Companies like Amazon and Alphabet are planning to spend about $700 billion this year, and, according to JPMorgan Chase's Jamie Dimon, that will increase to $1 trillion next year. Some of the biggest gainers aren't these hyperscalers themselves but the infrastructure companies that provide the data centers, energy, and memory products to make this all happen. A large chunk of the massive spend is going to these companies, and they're already experiencing incredible growth.
Bargains and Opportunities
Make sure you have a fully diversified portfolio that includes growth stocks to benefit from current AI trends, as well as defensive stocks in case the market crashes. This should always be your setup, but it's even more critical considering today's market conditions. If you've been focused on hot growth stocks, the time to make the shift is before things go south. By then, it will be too late. If your portfolio is packed with resilient dividend stocks, it will be able to withstand a downturn. Don't forget that the S&P 500 has always rebounded and gone on to new heights. There could be a prolonged period of weakness, as there was in 2000, when the broader index lost value for three consecutive years. But since 2003, it has gained 782%. Stay in it to win it.
Key points
- The S&P 500 is up 14% year to date.
- The market has enjoyed a strong bull run over the past three and a half years.
- Companies like Amazon and Alphabet are planning to spend billions on developing their AI platforms.
- The CAPE ratio has surpassed 40 only one other time.
- The market has been driven by artificial intelligence, which is a relatively new industry.
If the market continues to grow, investors could see even higher returns. Companies like Amazon and Alphabet are planning to spend billions on developing their AI platforms, which could lead to new opportunities for growth. Additionally, the S&P 500 has always rebounded and gone on to new heights, so there's a good chance that the market will continue to grow.
However, if the market crashes, investors could lose a significant amount of money. The CAPE ratio has surpassed 40 only one other time, and that led to a period of market losses. Additionally, the market has been driven by artificial intelligence, which is a relatively new industry, and it's unclear how it will perform in the long term.
