The markets are obviously extremely nervous about SGP - any bad news and they immediately tank! They're still potentially a growth bargain but it is hard to see them as having a long term future due to their current narrow market but who knows? I have shares in them (currently down) and expect to have to sell in the next year or two, as I do think they are likely to go out of fashion, so timing the sell will be critical.
There are some great articles offering advice on what to buy and why but very little on when to sell. Surely the same kind of stats that provide a reason to buy could be used to provide a reason to sell? It would be interesting to see articles on which shares are reaching their peak and would be best sold! Also, what sell strategies are being used by other members?
