The S&P 500 Index (SPX) is walking a tightrope right now. Geopolitical tensions are flaring, commodities are piling on the pressure, and all eyes are glued to the Federal Reserve's (Fed) September meeting.
So, what's the main engine behind the sour mood on Wall Street? A military conflict involving Tehran. Specifically, reports of destroyed Iranian tankers and a rapidly deteriorating situation in the Middle East have lit a fire under energy markets.
The pain is also being felt on the home front: American diesel prices have blown past $6 per gallon for the first time ever. With the White House warning that the conflict could drag on for years, investors are being forced to bake long-term inflation risks into their models, and this spells trouble for profit margins across most S&P 500 companies.
Not surprisingly, the surge in inflation anxiety has triggered a stampede out of government bonds. The yield on 10‑year US Treasuries has recently spiked to 4.95%, hitting multi‑year highs. Not even an emergency move by Secretary Scott Bessent, who announced a threefold increase in bond buybacks (to $6 billion) to calm the market, could reverse the tide.
High yields make stocks much less tempting for investors. Friday's trading session hinges entirely on the release of the Consumer Price Index (CPI) for August. If core inflation, expected to be 2.4% year-on-year, shows any sign of heating up, the US central bank will have all the cover it needs to act at its September 15-16 meeting.
As it stands, the CME FedWatch tool puts the odds of a 25‑basis‑point hike next week at 70%. On a smaller scale, however, the picture is still mixed: Apple (+3.6%) managed to prevent a full‑blown collapse in the tech sector, thanks to the successful unveiling of its $2,000 foldable iPhone Duo.
By contrast, chipmakers (NVIDIA, Micron) are sliding (−2.3% and −4.7%, respectively), as profit-taking ripples through the artificial intelligence (AI) segment. Retailers (Macy's, American Eagle) are waving warning flags as shoppers cut back on discretionary spending.
Historical seasonality adds another layer of gloom: September has traditionally been the weakest month of the year for US stocks. According to data from 1945 onward, the average decline is −0.6%.
With tough sanctions being announced against major foreign banks that aid Iran, the news backdrop is likely to remain bearish. If the Consumer Price Index (CPI) data overshoot forecasts, panic will intensify. SPX is expected to drift further toward the $7,400 support next week.
The ultimate recommendation is to sell the S&P 500 Index if inflation stays hot. Place Take Profit at $7,400. Set Stop Loss at $7,760.
Always size the position so that your potential loss (protected by a Stop Loss order) is no more than 1% of your account balance. If you can't open a position that meets such a risk criterion, it's safer to skip this trade and wait for a better, lower-risk opportunity.
