What happened Bioscience company ChromaDex (NASDAQ: CDXC) got off to a roaring start on Wednesday, rising nearly 29% in early trading, before melting to a 2.3% decline by midafternoon. A big distribution deal was the reason for the sudden pop. So what This morning, ChromaDex announced that its Tru Niagen dietary supplement will hit the shelves of Walmart (NYSE: WMT) beginning in June. Tru Niagen will be sold in two packaging options in the 3,000 stores where the product is being distributed. Remote shoppers can also purchase it through the Walmart e-commerce portal. ChromaDex claims that Tru Niagen, which is approved by the Food and Drug Administration, increases nicotinamide adenine dinucleotide (NAD) in the body. This chemical helps the body produce energy, and it declines with age. It can also be eroded, says ChromaDex, by stressors such as overexercising, lack of sleep, and alcohol consumption.

ChromaDex has not offered any forecasts as to how the Walmart deal will affect its fundamentals. Now what That morning euphoria might have been tempered by the realization that ChromaDex is still very unprofitable; its net losses have ranged from $4.2 million to almost $8.9 million over the last four quarters, on revenue that reached as much as $15.3 million. The Walmart news is certainly encouraging, but it seems the healthcare company needs a bigger portfolio to become a more-compelling investment case. 10 stocks we like better than CHROMADEX CORPORATIONWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
