One warning from social media app Snap was enough to send the U.S. stock market tumbling Tuesday, led by Big Tech, as investors worry about the possibility of a recession.

As this season’s retailer earnings reports have shown, consumers are choosing among discretionary goods. They aren’t buying TVs and home goods because they’re spending on travel. They are being forced to pay more money for food, fuel and other basic household goods.

Snap’s warning that macroeconomic conditions are deteriorating faster than expected “set fire” to the advertising sector on Tuesday, with a wide range of industry-related stocks falling on fears that companies will start recalling their “ad” dollars.

U.S. new home sales also fell 17% in April, the fourth consecutive monthly decline, which was also interpreted as a recession warning.

On Friday, the market will get fresh data on U.S. consumer spending, income and inflation, and on Wednesday, the Federal Reserve will release the minutes of its latest meeting. Market watchers will be watching the minutes closely for any additional hints on bank officials’ ideas ahead of next month’s meeting.

Here are 3 events that could impact the market on Wednesday:

1. NVIDIA EARNINGS

Chip maker NVIDIA is expected to report earnings of $1.30 per share on revenue of $8.1 billion, and analysts will be listening to what it has to say about supply and demand trends.

2. WILLIAMS-SONOMA EARNINGS

Kitchen and home goods retailer Williams-Sonoma is expected to report earnings of $2.88 per share on revenue of $1.8 billion, and analysts will try to compare the results of these upscale and specialty retailers to those of convenience stores and giant discounters.

3. DICK’S SPORTING REVENUES

Another retailer, Dick’s Sporting Goods, is expected to report earnings of $2.49 per share on revenue of $2.6 billion.
