Solar 3D Inc. (OTCMKTS:SLTD, SLTD message board)

Solar 3D Inc. ( OTCMKTS:SLTD , SLTD message board ) looks like it has become a darling with investors, and made an unbroken chain of daily climbs in the past month, starting the year at 3 cents and quadrupling its price. SLTD added more than 16% on Wednesday, reaching $0.115 on buying volumes above $720,000, the second-biggest buying spike in history. And ahead of the final days of the week, Thursday opened with a strong gain toward the 13-cent levels.

SLTD is a volatile selection, which in the past months swung between almost sub-penny levels and the current respectable price. What is even stranger is that the company has picked up without promotional emails, solely on its own efforts to post business updates.

SLTD is still expecting to continue the acquisition of SUNWorks, a solar panel company, thus giving exposure to a robust money-earner to the OTC markets.

This may be the reason for the newfound interest in SLTD. Now, the combined company also hopes that legislation to expand solar energy in California would hopefully boost revenues. And SVFC could certainly use some revenues, as its financials are running thin:

• Cash: $98 thousand

• total current assets: $103 thousand

• total assets: $132 thousand

• total current liabilities: $2.4 million

• revenues: $0

• net loss: $1.4 million

Eco energy is a sector that is also active on the OTC market right now, with different modes of alternative or green energy offered. As usual, the companies there show different profiles and different business potentials. Tiger Oil and Energy, Inc. ( OTCMKTS:TGRO ) rose in a similar run to a peak above $1.30, only to slide back and move to a lower range. But TGRO was also disproportionately boosted by promoters.

KleanGas Energy Technologies, Inc. ( OTCMKTS:KGET ) holds even more risk with a price below two cents, and a sudden spike from double-zero levels. With 400% gains made in a few short days, KGET is certainly a short-term star, but is also quickly sold off, entering a downward price spiral.

There is no guarantee how long the exuberance around green energy companies would continue. Paid promotions always play the biggest role, or another reason beyond the direct quality of the company, and no price range is immune to reversals, so choose your time frame well. In the case of SLTD, the peak price is always a threat for sudden reversal.
