Q3 Stock Prices A Mixed Bag
The economic uncertainty that has plagued the U.S. economy overall in 2023, including across the IT industry, continued through the third quarter amid rising interest rates and unclear signs as to whether a recession is on the horizon.
The wave of layoffs that swept through the IT vendors in late 2022 and the first half of 2023 continued in the third quarter as businesses prepared for a possible economic downturn.
The economic uncertainty was reflected in the stock prices of IT vendors. Among the 57 companies on the CRN watch list, 32 saw the price of their shares decline during the third calendar quarter (July 1 to Sept. 30) while 25 recorded share price increases. That’s a significant change from the first six months of the year during which only nine companies saw the value of their shares decline.
For the third quarter of 2023 the Dow Jones index was down 2.62 percent to 33,507.5 (its Sept. 29 close) while the tech-heavy NASDAQ was down 4.12 percent to 13,219.32.
