For CYCC, given its past ugly chart, I will not buy the earining winner today, there is not so much up and down in the history.

For TEUM, I won't buy either, given when price go up, there is always wall of selling, and the price just went down.

NETE, I will long the stock, given the positive catalyst often last 2 days, and the past history looks good.

I will buy BLDP, given below positive news. However, given the price is comparatively high. I will only buy small units.

For PLUG, FCEL, HPJ, there seems no catalyst for the stock.... so I wont buy.

For XXII, TRMR and MVIS, I will only deep buy... Given shorting those stocks are too dangerous given the past history.

For FALC, and MRNS, those two are top potentail dip buy, but still waiting for catalyst.
