Why did some dump their stock earlier today? They could have been long term holders, who have finally made it back into the green and took the opportunity to get their money back. It went to 4c, then fell back, which reminds us long-termers of all the other times, on good news, the SP has gone south. I have held shares since the MOZ days when it rocketed up to 14c, then went on a downward run for years. I have been in the red for ages but I refused to sell at a loss and steadfastly held on to my shares. Not very savy investing in the stock market I know ..... but I always believed in the Volt story. I have though, at times, kicked myself along the way for not selling, before I ended up in the red all those years ago, especially when it got down to sub 1c. I'm now nicely back in the green. No way will I sell. 6 years is a long time to hold with no reward but I think it's going to be well worth the agonising wait. Go Volt !!!!
