Sell, hold, sell half or wait? Thai answer: "Yes"

Must have been be a nice feeling to see a near 20% gain yesterday though

Not a share I follow or hold myself, so can't say much. At this price level it's not one I would buy into and would look more into research sites as a starting point like:
www.hl.co.uk/shares/shares-search-results/s/sabmiller-plc-ordinary-us-$0.10
www.digitallook.com/equity/SABMiller

Next price moves will centre around the possible bid and rumours, which is always going to be unpredictable.

If in your shoes I'd go back to first principles of:
- why are you holding it? what were your objectives at purchase? has it met them? what did you pay for it? etc
- looking forward has all that now changed?

If I was holding it and this gave a chance to realise a nice profit I'd be tempted to sell at least part as the middle path and hedging your bets.

Last one I had in this type of situation was AZN. I sold part and took part profits.

Always the risk that I could have made even more, but then again if a bid fails to materialise or just fails as it did in AZN's case it pulls back.

Also depends on your personality to an extent as well. I like the idea of taking part profits. I can always rationalise if it goes higher that I made money and took risk off the table with a decision that had a reasonable outcome. On the other hand if I take nothing and it pulls back...

Remembering that no-one calls the tops and bottoms exactly and "no-one ever became poor by taking profits" as they say making at least something would suit me.
