Arcadia Biosciences Inc (NASDAQ:RKDA) is once again on the top of the Nasdaq, following Friday's regulatory nod for its drought-tolerant soybeans. The equity has gapped another 39% higher to trade at $6.27, and hit a four-month high of $7.35 earlier. Plus, RKDA is eyeing its first close atop its 320-day moving average since late February.
Melinta Therapeutics Inc (NASDAQ:MLNT) is one of the worst performers on the Nasdaq, after H.C. Wainwright slashed its rating to "neutral" from "buy." The stock is down 8.7% at $2.60, headed for its fourth day in the red. While the equity is down on the day, it's still trading atop last Friday's two-month low of $2.18 -- suffered after a disappointing second-quarter earnings report and Melinta's CEO resignation.
