Time to dig out those people that call recessions for on-air appearances, TV bookers. 

Crude oil has now plunged into bear market territory. At about $43 a barrel, oil is at levels not seen since last August. Less than a month ago, oil was at $50 a barrel or so and blowhards were pounding the table on $60 to $70 a barrel this year. So much for that one. 

Bottom line is that there is too much oil on the market, which could be a function of slowing business conditions in emerging markets and, to a lesser extent, the U.S. What's more, shares of airlines such as American Airlines (AAL) - Get Report have fallen in response to lower oil prices, contrary to what one would expect. And, despite the increased purchasing power among consumers with gas prices trending lower, consumer stocks continue to trade with a downward bias. 

Add all these things together and it suggests something negative could be forming in the U.S. economy. Blame the rate-rising Federal Reserve, blame a dysfunctional Trump administration. Whatever the case, crude oil's crash should be taken seriously by the equity market perma bulls. 

What's Hot On TheStreet

Alibaba's Jack Ma woos Detroit: TheStreet has spent the past two days in Detroit covering Alibaba's (BABA) - Get Report big hiring event there. We have had the opportunity to talk with Alibaba and take in how the Chinese tech company plans to grow jobs in America. But the real showstoppers have been the presentations with Alibaba's executive chairman Jack Ma, who as always hasn't been short on bold proclamations. 

Said Ma in a keynote address Tuesday evening, "If you don't sell products in China, you will miss the future." Ma and other Alibaba executives have also sought to downplay the comparison to Amazon (AMZN) - Get Report . After spending a few days in Alibaba land, you understand where they are coming from. But, you are also reminded of how dominant Amazon is in the United States in so many categories (one soon to be organic food via Whole Foods (WFM) ).
