Have a lookat the recent share price history and trading volumes for dot-com minnow GPS Online (code GPO). Surely an ASIC investigation is due here? And what really p*sses me off is that I was given this tip a few weeks ago at a BBQ. But like all good BBQ tips, I ignored it…

CRIKEY: The chart shows that GPS Online‘s share price bolted from 0.021 cents to 0.029 cents on September 29. The company called a trading halt on 13 October. On 17 October the company announced it was acquiring Advanced Mining Technologies for $10 million. Since then, shares have risen another cent to 0.043, and the volume of shares traded has increased tenfold. Interesting.
