| Comment | 1.650 | Bill Carrigan | Most of the stocks in this space have been rallying. On concept stocks it is important to see what the peers are doing. This has probably bottomed. Don't let it make a new low. Thinks this will be OK. | 2007-07-10 | |
| SELL | 1.460 | Bill Carrigan | This whole sector is compelling. Recommends being careful and to diversify. The stock has had a nasty downward trend. Recommends to reduce in a rally if possible and sell on strength. | 2006-10-02 | |
| TOP PICK | 6.200 | Bill Carrigan | Has a nice long term base and is just rallying. Alternative energy should be good at this time. Make sure you have a stop loss. $4.90 would be good. | 2005-03-15 | |
| TOP PICK | 7.610 | John Clarke | This is one of the concept stocks you should hold in an energy portfolio towards the future. | 2003-10-27 | |
| BUY | 6.030 | John Clarke | Just made a new, good acquisition, but will not be profitable until 2006. | 2003-03-27 | |
| DON'T BUY | 6.630 | Rob Peets | Interesting technology. May take a long time. | 2003-01-28 | |
