I will go for SLG with the proviso that if it moves up 0.5p, I think it may get re-rated.
Been dropping since it peaked from float in March at something like £1.30, delays & factory problems (now rectified) means it has sunk to a new low of circa 24p.
It is trading at a market cap backed by cash, has very worthwhile IP/patents & is a world leader with sales going through the roof.
So at sometime will get re-rated imo, last week the fall stopped and rose 0.5p a day before the last trading day of the year, of course it could be a blip, could be the start of the re-rating.
