You never know what you're going to see as far as headlines on any given day. But make that day a tinderbox of trader nerves, waiting for a quarterly USDA report, and volatility in grain markets could quickly spike. Such was the case Friday when a news story was released with the explosive headline, "Exclusive: China Set to Export Corn, Posing New Threat to Battered Global Market -- Sources."

In today's algorithmic trading, headlines, especially bearish ones like this, matter. Watson (my name for high-frequency computerized trade as an entity), doesn't have the nanoseconds to read the entire story, which makes long headlines full of charged words, even more of a concern.

So what about the story. Those familiar with China, and the grain and oilseed markets, know it's nothing more than a game. Will China really export corn? Possibly. Will it "pose a new threat to battered global market?" No. As DTN Analyst Todd Hultman was quick to point out "the article talks about 2 million metric tons of corn, which if true, is nothing. China is expected to import 3 mmt during the current 2016-17 marketing year." He went on to say, "I continue to have big doubts that China's supply problems are a threat to world supplies. This is a domestic issue from a big consumer that is struggling to stay self-sufficient in corn and wheat."
