It a difficult one announcing when you have sold ... I think that holding a position (especially a substantial holding) in a company and suddenly announcing that you have sold out immediately or shortly after your last trade is often construed by many as an attempt to D/Ramp a stock.... and in 90% of cases thats exactly what they are doing. Unfortunately many unscrupulous traders use this strategy for that very reason. To force the price down to rebuy again at a lower price a practice I find particularly distasteful and deem those that execute this strategy as lacking in trading general skill (not the least moral fibre...).
Personally I prefer to let the stock follow its own path after I have left and not be influenced or forced down by the fact that I have left the register. I am quite happy to let people know when I am entering taking pilots or growing my posy early as they can choose to buy or not... but am hesitant to announce when I have left, usually not mentioning it at all or leaving it till a few weeks after the fact so it can plot its own course after Ive gone. I think its important that people determine their own time when to sell depending on their own goals and exit strategy, sometimes I sell way too early anyway. I think all great trades are made at the point of entry ... If you don't have a good entry you'll the chances of a good exit are depleted significantly.
