Here we go again, Monday morning, and another busy week in the offing, with many 31 Dec trading statements likely. I'm pleased to say my DryAthlon is going well, haven't touched a drop of booze since 29 Dec. Better still, the donations for Cancer Research (almost all from readers here!) have already hit 155% of target - awesome! Thank you to everyone who has donated, it's much appreciated.

Sarantel Group (LON:SLG) has finally run out of investor appetite for repeated fund-raisings, and has put itself up for sale, having just reported on another year (ended 30 Sep 2012) where it burned around £2m in cash losses.

Pity, as I always thought their product (high performance, small antennae for high end mobile devices) has great promise, but as is often the case with new technology it takes longer & costs far more to commercialise things than originally planned.

I can't just make a leap in the dark with no forecasts, so unless & until they commission some research and issue it to the market, then the shares can't possibly go into my portfolio. Pity, as I like the look of it.

Bioquell (BQE) is one that got away - it came…
