US stocks are seen heading north at the open, but in pre-market deals several stocks are trending.
One is well-known fastfood chain Chipotle Mexican Grill Inc (NYSE:CMG), which saw shares lose 1.39% to US$459.
It comes after the group, which has never been far removed from controversy in recent years, reportedly shut a restaurant in Ohio following reports of customers getting sick.
At least two diners have reportedly written on the food safety website iwaspoisoned.com that they suffered nausea and diarrhea after eating there.
Those who haven't been put off from heading to the burrito chain Tuesday can enjopy free guacamole today with online and mobile app orders.
The special deal is for National Avocado Day and for one day only.
Elsewhere, shares in Lumber Liquidators Holdings Inc (NYSE:LL) got the chop in pre-market, shedding almost 10% before the bell as the wood flooring company reported a surprise second-quarter loss.
The group swung to a net loss of US$1.5mln in the three months, against a profit of US$4.5 mln in 2Q of 2017.
Illumina Inc (NASDAQ:ILMN) was another share in the frame in pre-market trade, with shares surging 7.18% to US$310 after its second quarter numbers beat analyst expectations.
The California-based diagnostics group reported adjusted earnings of $212 million or US$1.43 per share for the three months.
Consensus was for US$1.11 per share.
Finally, Ralph Lauren Corp (NYSE:RL) saw shares nudge 0.012% higher at US$135.91 ahead of its quarterly numbers.
The Street expects the fashion brand to post earnings of US$1.36 per share on revenue of US$1.36bn.
Like many clothes retailers, the firm has suffered falling revenues and loss of brand appeal and has aimed to reduce its dependence on bricks-and-mortar stores.
However, while this boosts the bottom line, it has had a negative impact on revenues, so investors will be keen to see what the latest trends are.
