Wall Street ended a turbulent week on a cautious note Friday, November 13, 2026, as semiconductor stocks declined, government bond yields climbed, and investors continued questioning the outlook for artificial intelligence.

The Dow Jones Industrial Average managed a modest 0.1% gain, but the S&P 500 fell 0.4%, while the technology-heavy Nasdaq Composite dropped 0.9%.

In Canada, the S&P/TSX Composite closed at 36,105.90, down 31.29 points, or 0.09%.

The day’s biggest technology story was Nvidia. Its market capitalization finished below $4 trillion amid continued uncertainty surrounding the departure of longtime CEO Jensen Huang.

Meanwhile, the benchmark 10-year U.S. Treasury yield reached 5.17%, its highest level since October, as investors prepared for the possibility of another Federal Reserve interest-rate increase in December.

Inflation remained central to the market’s concerns. October’s Producer Price Index rose 0.3% month over month, below economists’ 0.4% forecast, but the annual increase of 6.5% suggested that price pressures remained persistent.

Bitcoin also came under pressure, falling below $70,000 for the first time in nearly three months.

Despite Friday’s weakness, the major U.S. indexes reportedly finished the week with gains.

The central story of November 13: Investors are reassessing the risks of expensive technology stocks as inflation, higher interest rates, and corporate uncertainty challenge confidence in the AI boom.

1. How the Major Stock Indexes Performed

Index	Daily change	Closing value
Dow Jones Industrial Average	+0.1%	Not supplied
S&P 500	−0.4%	Not supplied
Nasdaq Composite	−0.9%	Not supplied
S&P/TSX Composite	−0.09%	36,105.90

The Nasdaq was the weakest of the four major indexes, reflecting selling pressure in semiconductor and technology companies.

The Dow’s modest gain suggested that some investors were shifting toward companies less directly exposed to the AI investment cycle.

Canada’s TSX experienced a comparatively small decline, finishing just 31.29 points lower.

Although the major U.S. indexes reportedly gained ground for the week, Friday’s performance revealed continued investor nervousness.

What changed during the week?

Monday began with a strong rally.

Tuesday brought selling pressure after U.S. consumer inflation exceeded expectations.

Wednesday saw technology stocks recover, helped by Nvidia and CoreWeave.

Thursday’s session weakened as bond yields rose and Nvidia’s leadership transition became a central concern.

By Friday, investors were once again reducing their exposure to semiconductor stocks.

This sequence illustrates how rapidly sentiment can shift when markets are influenced by several competing forces.

2. Nvidia Falls Below $4 Trillion in Market Capitalization

Nvidia remained at the center of Wall Street’s attention Friday.

Shares declined again, pushing the company’s market capitalization below $4 trillion.

The decline followed a turbulent week involving reports of CEO Jensen Huang’s departure and controversy surrounding his personal conduct.

Investors are now evaluating what the leadership change could mean for Nvidia’s future.

Why Nvidia is so important

Nvidia is a central supplier of the computing technology used to develop and operate advanced artificial intelligence systems.

Its graphics processing units power large AI data centers operated by major technology companies and cloud computing providers.

The company also has extensive relationships throughout the AI industry.

Its products, software, partnerships, and investments have helped establish Nvidia as one of the most influential companies in the global technology economy.

As a result, developments at Nvidia can affect sentiment toward many other businesses.

The significance of a $4 trillion valuation

A market capitalization of $4 trillion reflects extraordinary expectations about future profits.

When investors value a company so highly, even relatively small changes in expectations can produce enormous changes in its market value.

A 1% move in a company valued at $4 trillion represents approximately $40 billion.

That is larger than the total market capitalization of many publicly traded businesses.

This helps explain why Nvidia’s volatility has attracted so much attention.

Earnings become even more important

Nvidia is expected to report third-quarter earnings next Tuesday, November 17, according to the supplied reporting.

Investors will be watching closely for evidence that demand for AI computing remains strong.

Important questions include whether revenue growth is meeting expectations, whether profit margins remain healthy, and whether customers continue expanding their AI infrastructure investments.

Investors will also be interested in how Nvidia’s leadership transition affects its business strategy.

Nvidia’s next earnings report could become an important test of confidence in the broader AI investment boom.

3. Semiconductor Stocks Fall as Investors Reconsider AI Valuations

Nvidia was not the only semiconductor company facing selling pressure Friday.

AMD and Broadcom also declined as investors reduced exposure to the chip sector.

The selloff reflected growing uncertainty about the sustainability of the artificial intelligence investment boom.

Is the AI boom slowing down?

Artificial intelligence continues attracting enormous investment from technology companies.

Businesses are spending billions of dollars building data centers, purchasing specialized processors, and developing AI software.

However, investors are increasingly questioning whether these expenditures will generate sufficient financial returns.

This is an important distinction.

An industry can grow rapidly while the stocks of companies operating within that industry decline.

A historical comparison: The internet boom

During the late 1990s, investors became enthusiastic about the internet’s potential to transform the economy.

They were correct about the technology’s long-term importance.

However, many internet-related stocks reached valuations that were difficult to justify.

When the dot-com bubble burst in 2000, numerous companies experienced substantial declines.

Some disappeared entirely.

Others, including Amazon, eventually became enormously successful businesses.

The lesson is not that artificial intelligence will follow exactly the same path.

Rather, technological progress and investment returns are two different things.

The question is not simply whether AI will change the world, but whether investors are paying a reasonable price for the companies expected to benefit.

4. Treasury Yields Reach 5.17% as Bond Markets Sell Off

U.S. 10-Year Treasury Yield

5.17%

Reported intraday high · November 13, 2026

Market significance: Rising Treasury yields increase borrowing costs and make expensive growth stocks more sensitive to changes in interest-rate expectations.

One of Friday’s most significant developments occurred in the bond market.

The benchmark 10-year U.S. Treasury yield climbed as high as 5.17%, its highest level since October.

The increase followed several days of rising concerns about inflation and Federal Reserve policy.

Why do bond yields rise when bond prices fall?

Bond prices and yields move in opposite directions.

When investors sell existing bonds, their prices decline.

Because the payments on those bonds are generally fixed, the yield available to a new buyer increases as the price falls.

This is why a bond-market selloff can produce higher Treasury yields.

Why a 5% Treasury yield matters

Government bonds are often considered relatively low-risk investments, particularly when held to maturity.

When these bonds offer yields above 5%, investors have an alternative to riskier assets.

A company with uncertain future profits may become less attractive when investors can earn substantial interest from government securities.

Higher yields also affect the cost of mortgages, corporate borrowing, and government financing.

For technology companies investing heavily in AI infrastructure, financing costs can become an important consideration.

What this means for the stock market

Higher interest rates can put downward pressure on stock valuations.

This effect is often especially pronounced for growth companies.

Investors value stocks partly on the profits they expect companies to generate in future years.

When interest rates rise, the present value of those future earnings declines.

This helps explain why technology stocks have been particularly sensitive to changes in Treasury yields.

5. Wholesale Inflation Remains Elevated Despite a Softer Monthly Reading

U.S. Producer Price Index — October 2026

Wholesale inflation

Monthly actual

+0.3%

Monthly forecast

+0.4%

Annual inflation

+6.5%

October actual

0.3%

Economists’ forecast

0.4%

Monthly PPI was 0.1 percentage point below expectations, but annual wholesale inflation remained elevated.

Friday’s economic data provided a mixed picture of inflation.

The Producer Price Index increased 0.3% in October, slightly below economists’ expectation of 0.4%.

At first glance, that appeared encouraging.

However, wholesale prices were reportedly 6.5% higher than a year earlier.

This suggested that inflationary pressures remained significant.

What is the Producer Price Index?

The Producer Price Index measures changes in prices received by domestic producers for goods and services.

It differs from the Consumer Price Index, which measures changes in prices paid by consumers.

Producer prices can provide useful information about inflationary pressures within the economy.

When businesses face higher costs, they may attempt to pass some of those increases along to customers.

However, the relationship is not automatic.

Businesses may absorb some costs through lower profit margins, while other prices may be influenced by competition and consumer demand.

Why the annual number matters

Although October’s monthly increase was below expectations, the annual rate remained high.

This indicates that businesses are still operating in an environment of substantial price increases.

For the Federal Reserve, persistent inflation makes monetary policy more complicated.

Reducing interest rates too quickly could risk allowing inflation to remain elevated.

But keeping rates high for an extended period could slow economic growth.

The central bank must balance these competing concerns.

6. The Federal Reserve Faces Growing Pressure to Raise Rates

Friday’s inflation report reinforced expectations that the Federal Reserve could raise interest rates at its December meeting.

Earlier in the week, October consumer inflation had also exceeded economists’ forecasts.

Together, the CPI and PPI reports suggested that inflation remained a significant concern.

Why the Fed might raise rates

Higher interest rates tend to reduce borrowing and spending.

They make mortgages, business loans, and other forms of credit more expensive.

This can slow economic activity and reduce demand-driven inflationary pressure.

However, higher rates also create challenges.

Businesses may postpone investments.

Consumers may reduce spending.

Employment growth can weaken.

Financial markets may also experience increased volatility.

What investors should watch

The most important question is whether inflation continues easing or remains stubbornly elevated.

Investors will also be watching employment data, consumer spending, and comments from Federal Reserve officials.

The December rate decision has not yet been made.

Market expectations can change as additional economic information becomes available.

For now, however, the possibility of tighter monetary policy remains an important source of uncertainty.

7. Canada: TSX Ends the Week Slightly Lower

Canada’s S&P/TSX Composite finished Friday at 36,105.90, down 31.29 points, or 0.09%.

The modest decline was considerably smaller than the Nasdaq’s 0.9% loss.

This reflected the different composition of the Canadian and American stock markets.

Why Canada’s market is different

The Canadian stock market has substantial exposure to financial institutions, energy producers, mining companies, and other resource-related businesses.

The Nasdaq, by contrast, is heavily influenced by technology companies.

When semiconductor stocks experience a significant selloff, the Nasdaq may decline more sharply than Canada’s TSX.

However, Canada’s market remains exposed to global economic risks.

Higher interest rates can affect Canadian banks, businesses, and consumers.

Changes in oil and metals prices can influence resource companies.

And shifts in U.S. economic policy can affect Canada through trade and investment relationships.

Canada’s performance this week

The TSX experienced several significant daily movements.

It rallied strongly Monday, declined Tuesday, recovered Wednesday, and fell again Thursday.

Friday brought a comparatively small decline.

The index nevertheless finished above its previous Friday closing level of 35,789.09, based on the figures used in this newsletter series.

That would represent a weekly gain of approximately 0.89%.

This demonstrates that a market can experience substantial daily volatility while still producing a positive weekly return.

8. Oil Prices Stabilize After a Volatile Week

Oil prices were relatively stable Friday after a sharp increase earlier in the week.

The rebound had been influenced by renewed concerns about the U.S.-Iran conflict.

Brent crude had risen toward $96 per barrel during the week.

Why oil prices matter

Energy prices affect many areas of the economy.

Higher oil prices increase transportation and production costs.

They can contribute to higher gasoline prices and influence consumer inflation.

For Canada, oil prices are especially important because the country is a major energy producer.

Higher crude prices can support the earnings of Canadian oil companies.

However, they can also increase costs for consumers and businesses.

Oil and inflation

Energy markets are particularly important when inflation is already elevated.

A sustained increase in oil prices can make it more difficult for central banks to bring inflation under control.

This may strengthen expectations that interest rates will remain high or increase further.

For investors, oil prices are therefore both a commodity-market story and a monetary-policy story.

9. Bitcoin Falls Below $70,000

Bitcoin

Below US$70,000

Reported Friday, November 13, 2026

Market context: Bitcoin fell below $70,000 for the first time in nearly three months as higher yields and tighter monetary-policy expectations weighed on risk-sensitive assets.

Bitcoin fell below $70,000 Friday, marking its first move beneath that threshold in nearly three months.

The decline occurred as investors reassessed the outlook for interest rates and reduced exposure to speculative assets.

Why higher interest rates affect bitcoin

Bitcoin does not generate interest income or corporate profits.

Its value depends heavily on supply, demand, adoption, liquidity, and investor expectations.

When government bonds offer higher yields, investors may become less willing to hold highly volatile assets.

Higher interest rates can also reduce the availability of cheap financing.

This can limit speculative investment activity.

Is bitcoin a safe haven?

Bitcoin is sometimes described as digital gold.

However, its price behavior can differ significantly from traditional safe-haven assets.

During periods of financial stress, bitcoin has sometimes declined alongside technology stocks.

Friday’s performance demonstrated that cryptocurrency markets remain sensitive to broader changes in investor sentiment.

Investors should therefore be cautious about assuming that bitcoin will automatically protect a portfolio during market downturns.

10. The Week in Review: November 9–13, 2026

The week was marked by sharp reversals in investor sentiment.

Five Days That Tested Investor Confidence

1. Monday, November 9 — Stocks rallyU.S. markets surged, with the Dow gaining approximately 2.2%, the S&P 500 advancing 2.3%, and the Nasdaq climbing 2.7%.
2. Tuesday, November 10 — Inflation surprisesOctober CPI rose 0.4%, exceeding expectations and sending U.S. and Canadian stocks lower.
3. Wednesday, November 11 — AI stocks reboundThe Nasdaq gained 1.6%, while CoreWeave surged 24% following encouraging financial results.
4. Thursday, November 12 — Bond yields riseNvidia leadership uncertainty and Treasury yields above 5% weighed on markets. The TSX declined 0.75%.
5. Friday, November 13 — Semiconductor selling resumesNvidia’s market value slipped below $4 trillion, the Nasdaq fell 0.9%, and bitcoin dropped below $70,000.

Despite the turbulence, the major U.S. stock indexes reportedly posted gains for the week.

The important lesson is that daily market headlines can sometimes obscure the broader direction of financial markets.

A particularly negative trading session does not necessarily mean that an entire week or month has been negative.

Investors should therefore evaluate market performance over multiple time horizons.

11. What Investors Should Watch Next Week

Nvidia’s third-quarter earnings — Tuesday, November 17

The company’s results and outlook could influence sentiment across the semiconductor and AI sectors.

Federal Reserve expectations

Investors will watch for changes in expectations surrounding a possible December interest-rate increase.

Treasury yields

Will the 10-year yield remain above 5%, or will bond markets stabilize?

AI sector confidence

Investors will continue evaluating whether strong demand for AI computing can justify elevated stock valuations.

Oil and geopolitical developments

Changes in energy prices could influence inflation expectations and Canadian resource stocks.

12. The Biggest Investment Lesson of November 13

Friday’s market performance provides an opportunity to reflect on the relationship between innovation, valuation, and investment risk.

Nvidia has played a central role in the development of artificial intelligence.

Its products have enabled major advances in computing and helped create an enormous new market.

Yet even a company with exceptional technology can experience significant stock-price declines.

Investors must distinguish between a company’s importance to the economy and the attractiveness of its shares at a particular price.

A company can be innovative, profitable, and strategically important while still being overvalued.

This distinction becomes especially important when interest rates rise.

Higher yields make future profits less valuable in present-day terms, potentially reducing the prices investors are willing to pay.

Corporate governance and leadership also matter.

A company may possess extraordinary technological capabilities, but uncertainty about its management can affect investor confidence.

For long-term investors, these developments reinforce the importance of diversification.

Concentrating a portfolio in a single company or industry can expose investors to risks that are difficult to anticipate.

The objective is not to identify the most exciting technology. It is to purchase productive assets at reasonable prices while managing risk.

Conclusion: A Positive Week Ends With Renewed Caution

Friday, November 13, 2026, ended a volatile week for U.S. and Canadian financial markets.

The Dow gained 0.1%, but the S&P 500 declined 0.4% and the Nasdaq fell 0.9%.

Canada’s S&P/TSX Composite slipped 0.09%, closing at 36,105.90.

Nvidia’s market capitalization fell below $4 trillion as investors continued evaluating its leadership transition and the outlook for AI spending.

The 10-year U.S. Treasury yield reached 5.17%, while wholesale inflation remained elevated at 6.5% annually.

Bitcoin fell below $70,000, reflecting the pressure that tighter financial conditions can place on speculative investments.

Despite these developments, the major U.S. indexes reportedly finished the week higher.

The contrast between weekly gains and daily volatility illustrates an important investing principle.

Financial markets can experience considerable uncertainty without necessarily abandoning their longer-term trends.

For long-term investors, patience, diversification, and disciplined valuation remain more useful than attempting to react to every market headline.
