From a technical point of view Codexis looks very promising, but don’t forget the inherent risks of a stock with only 90 Mio market cap !
At the moment the stock price lingers above the 50 day moving average. If the important 200 day moving average at about 2.60 can be broken it could go up to 3$.
Support: 2.30, 2.00 und 1.80
Resistance: 2.60, 3.00 und 3.50
