I bought at 57 cents and sold at $1.33 when it was revealed to me that they share price was grossly inflated and watched the sp with amazement going past two dollars mark- the reality is there was no evidence to supports the sp over 22 cents then as is the case now.
it's a logical concept - and well worth the effort for future research, but I don't think I would rush into buy again above 22 cents.
