Strong runs for some transportation and machinery stocks this year may soon come to an end, "Fast Money" traders contended Wednesday.
Shares of rail company Kansas City Southern and industrial players Caterpillar and Deere have climbed at least 5 percent each this year. Amid continued uncertainty for commodities and emerging markets, those stocks could soon reverse course, traders said.
Kansas City Southern's stock closed Wednesday around $83.40 per share. After a run-up of nearly 12 percent this year, its shares look appealing as a short against $85 per share, argued trader Guy Adami.
