S&P 500 Flat as Wall Street Braces for September Volatility: What History and Data Are Telling Us

Key Highlights:

• The S&P 500 and Nasdaq struggle to stabilize after a sharp sell-off, with tech stocks leading the decline.
• September is historically the weakest month for stocks, but election-year patterns offer hope.  
• Economic data and the upcoming Federal Reserve meeting will play a crucial role in shaping the market.

Wall Street’s a bit wobbly right now. The S&P 500 is clinging to the flatline after Tuesday’s sell-off, with tech giants like Nvidia and Amazon leading the charge downward. The Nasdaq? It dropped by a painful 3.26%, leaving traders wondering if there’s any light at the end of this September tunnel. And here’s the kicker: September, historically, hasn’t been kind to equities.

But while the market might be feeling shaky, it’s not all doom and gloom. If history’s anything to go by, this month could offer some interesting twists—especially with the 2024 U.S. presidential election looming. If you’ve been following the market long enough, you know that election years have a funny way of shaking things up.

September’s Bad Rap: Is This Just Another Bump in the Road?

Let’s be real: September has never been a favorite for investors. As per State Street Global Advisors, Over the last 98 years, it’s the only month where the S&P 500 has averaged a negative return. And this isn’t just a fluke—September’s earned that bad rep. But here’s where things get interesting. Despite its gloomy historical record, the S&P 500 has actually ended the month in the green more often than you’d think.

And then there’s the election-year wildcard. Historically, Septembers leading up to a U.S. presidential election tend to perform better than those in non-election years. It’s not just optimism in the air—markets are often buoyed by anticipation of policy shifts or even a potential economic stimulus. And in a year like 2024, where everyone’s watching the race to the White House, that could play into how things unfold this month.

The Latest Data: When Manufacturing Reports Rock the Market

So, what’s behind this week’s market tumble? We’ve got a mix of disappointing manufacturing data and nervous tech traders. The Institute for Supply Management (ISM) and S&P Global’s latest manufacturing reports sent a chill down Wall Street’s spine, both pointing to slower-than-expected growth. And in a market that’s become hyper-focused on every economic data point, that’s enough to trigger a wave of selling.

But it wasn’t just the numbers—it’s where the numbers hit hardest. Nvidia, the darling of the chip world, took a 9% dive after a news on U.S. Justice Department subpoena spooked investors. Combine that with a tech sector already under pressure from rising rates, and you’ve got a recipe for a steep slide. The S&P 500’s information technology sector posted its worst day since September 2022, with the VanEck Semiconductor ETF (SMH) dropping more than 7%.

What’s Next: Investor Sentiment and Predictions

September might just be getting started, but many investors are already bracing for more bumps in the road. Some are expecting the S&P 500 to drop another 5% or more as we push further into the month.

But for others, like Chris Hyzy from Bank of America Private Bank, this dip is more of an opportunity than a reason to panic. He’s urging investors to take a long-term view, seeing these volatile weeks as the perfect time to rebalance portfolios and diversify ahead of what could be a busy Q4.

It’s not all about tech and manufacturing, either. Earnings season may have mostly wrapped up, but there’s still plenty to watch. Take Dollar Tree, for instance—it tumbled 19% after cutting its guidance, raising questions about the strength of the U.S. consumer. These post-earnings moves add to an already jittery market, where one headline can make or break a stock.

Election Year Optimism: Will It Save the Day?

Here’s where things get a little more hopeful. Election years often come with a certain level of market optimism. Historically, stocks tend to perform better in the months leading up to the U.S. presidential election, as investors anticipate policy changes that could impact the market. And while we can’t predict exactly how this year will play out, the historical trend has shown that election-year Septembers can surprise us—in a good way.

While election-year optimism is real, it’s often tempered by the broader economic picture. Right now, all eyes are on the August jobs report and the Federal Reserve’s next move. A strong labor market could calm some nerves, but if the jobs data disappoints, we could be in for more volatility before things settle down.

Economic factors to watch:

- The upcoming August jobs report will be a key indicator of where the U.S. economy is heading.  

- The Federal Reserve’s meeting on September 18, where a 25-basis-point rate cut is expected, could either calm markets or stir the pot even more.

Navigating September’s Choppy Waters

Let’s face it—September isn’t an easy month for anyone, especially in the stock market. But while the current volatility is rattling nerves, it’s not all bad news. History shows that September’s weakness doesn’t always last, particularly in election years where markets often find their footing before November.

So, what should you do? Stay cautious but don’t overreact. With key data points like the jobs report and the Fed meeting on the horizon, there’s still time for the market to find its balance. And for those willing to navigate the ups and downs, there might even be some opportunities hiding in the volatility.

In short, buckle up—this September’s ride might be bumpy, but it’s far from over.
