David Pinsen submits:
Alloy Steel International (AYSI.OB) is a nano cap company headquartered in Australia that uses a high tech, proprietary process to manufacture protective wear plates for mining equipment. Essentially, the company is a picks & shovels play on the mining industry (particularly iron ore and coal mining, currently), an industry which has of course benefited from the demand for industrial commodities by China and other emerging economies.
Alloy Steel was the subject of a few posts here by Seeking Alpha contributer Michael Alexander, including (most recently) this post from last February, "AYSI’s disruptive technology leads to record growth and earnings". Since then, the stock has dropped by more than two thirds. Much of that drop occured after the company’s most recent quarter showed lower earnings than shareholders (including me) expected.
