What explains the recent massive sello in the stock

market in recent days? Is it fundamentally driven? Or is

there cause for concerns?

Stock returns respond to news that are difficult to predict,

which means that it is difficult to predict the stock returns by

simply relying on past information. However, relying on key

market principles can still be useful to better understand

investors’ behavior. Here, I will consider three key factors:

• Macroeconomic performance

• Forward guidance of the Federal Reserve Bank

• Uncertainty

The recent positive job market report was released on June

, 2026. However, the US stock market experienced a

massive selloff last Friday, which persisted until June 10

2026. One of my former economics students asked me the

following question via chat:

o Why would the stock market experience a negative

downturn when there is robust evidence of strong job

performance?

To answer the latter, it is important to understand

that not all positive job market reports are created

equal. A positive job report in a low inflationary environment is

not so bad for stock market confidence. Particularly, because

investors do not anticipate massive inflationary pressures. But

what exactly are the consequences of inflationary pressures on

the capital market?

o Lower expected inflation increases the real expected

return on bonds. As bond prices rise due to higher

demand, interest rates fall. This makes stocks more

attractive.

o Higher expected inflation causes the opposite effect: the

real expected return on bonds fall. As the demand for

bond falls, bond prices fall, interest rates rise. This

makes stocks less attractive in contrast to treasury bills

or other types of fixed-income assets.

o If the FED still believes in some kind of inflation target

, it might signal its intension to raise rates in the

upcoming meetings on June 16

(forward guidance).

However, what exactly is the inflation target of the FED?

A better question lies in how credible is that target?

Again, for my money and banking students, when I am

talking about raising rates. Think about the Federal

Reserve Bank of New York engaging in a large open

market sale of short-term treasury bills in the over-the-

counter market; which is aimed at targeting a higher

federal funds rate.

If consumer price inflation was around 2 %, a positive job

report would have been associated with some modest increase

in investor confidence. However, the recent positive job news

comes with rising inflationary pressures induced by the recent

targeted tariffs and the US-Iran war. Moreover, consumer price

inflation is now at 4.2%; which is well above the FED’s official

target . Therefore, despite the recent job claims, the high

inflationary environment has had a negative effect on investors’

confidence. This partially explains the massive selloff that

recently took place in the market ahead of the FED’s upcoming

meeting on interest rates. Moreover, historically, Figure 1 shows

that uncertainty in consumer price inflation is positively and

strongly associated with uncertainty in stock market

performance in the United States.

Figure 1: Macroeconomic Uncertainty

As shown in Figure 1, consumer price inflation uncertainty

is rising; mainly due to the sharp increase in crude oil prices.

Moreover, with the possibility of an interest rate hike, it is

interesting to see how the stock market will respond in the next

couple of weeks. What is certain on paper is that the stock

market has experienced a significant increase in volatility in the

past couple of weeks; which could be explained by a significant

increase in macroeconomic uncertainty.
