Not all Dow components declined on Tuesday as trade war worries reached fever pitch.

Walmart (WMT - Get Report) , Verizon (VZ - Get Report) and Procter & Gamble (PG - Get Report) ended in positive territory. But that wasn't enough to keep the blue chip index from falling 287 points, thanks to steep declines from Boeing (BA - Get Report) , Caterpillar (CAT - Get Report) and United Technologies (UTX - Get Report) , which have exposure to China.

Matthew Cheslock, an equity trader with Virtu Financial doesn't think stocks are low enough to warrant a buying opportunity just yet.
