Why the S&P 500 Index has dropped this year 

Most companies in the S&P 500 Index have dropped this year because of the ongoing Iran war, which has pushed energy prices higher.

Brent and the West Texas Intermediate (WTI) have jumped by double digits since the war started a few weeks ago. As a result, the headline and core consumer price index (CPI) data are expected to continue rising, and possibly hit the key milestone at 3% this year.

As a result, US bond yields have continued rising, with the 10-year and 30-year rising to 4.3% and 4.8%, respectively. This jump is mostly because investors anticipate the Federal Reserve will either leave interest rates unchanged between 3.50% and 3.75% or hike rates this year.

The S&P 500 Index has also dropped because of the ongoing concerns about the private credit industry, where some top companies like Blackstone, Ares, and Blue Owl have continued to restrict withdrawals. As such, there are concerns that the private credit bubble may be about to burst.

The index has also slumped amid the rising concerns about the artificial intelligence (AI) industry. Software stocks have slumped amid concerns that tools being made by companies like Anthropic will disrupt their business models.

Top gainers in the VOO ETF this year 

Some notable companies in the S&P 500 Index have done well in the past few months. Memory chip companies like Sandisk, Western Digital, and Seagate Technology stocks have jumped by 187%, 70%, and 50%, respectively. 

This surge happened as the memory chip shortage continued, pushing them to boost prices and margins. For example, analysts expect that Sandisk’s revenue will jump by 112% to $15.5 billion this year.  They also expect that Western Digital’s revenue will jump by 30% to $12.47 billion.

Texas Pacific Land stock has jumped by 88% this year, while companies like Ciena, LyondellBasell, Moderna, APA Corporation, Dow, and Teradyne have all jumped by over 60% this year.

Some of the other top gainers this year are companies like Marathon Petroleum, Occidental, Valero, and Phillips 66. These companies are doing well as crude oil and natural gas prices soar.
