TPS, formally Turbo Genset has been in my portfolio for some time (2004 I think I bought it). Basically I bought it when I first started buying shares and watched it go down because of operating losses. Having watched it go down to a point where it wasn't worth selling I have kept this 'dog' and watched some more...not the best way to run a portfolio.
Over the past year or so TPS have consitently won new contracts and I do feel that after bottoming out at 8p ish that the future of this company is a good one. They just quietly plug away at running their business and sooner or later they are going to get noticed and make profits. My dog could become a thoroughbred yet!
Here is the latest note about them in T1ps yesterday;
'Electrical power solutions operator Turbo Power Systems (TPS) saw its shares firm 0.625p to 8.625p following news of a contract win. Revelations of further orders worth 1.2 million pounds from the National Railway Equipment for traction motor controllers were accompanied by first quarter figures. Numbers for the first quarter to 31st March showed a 25% reduction in losses to 1.4 million pounds, as a 122% rise in production and development income to 2.4 million pounds was recorded.'

Thanks for that 4P a fall today however not massive and it looks as if the buyers are beginning to filter back in.

This is a real rollercoaster share, getting in and out at the right time could see mega profits.
