The best thing usually is to learn from it if you can by studying the charts
The basic rule is never buy or hold in a stage 4 down trend.
Try and pick an up-trend especially from a low base.
If you bought ok and it did go up considerably and you held when it went up and down, try and work out when you should have sold.
I've never lost that much on a spec share (and it depends on how many you held as to how serious it is), but the losses have made are now lessons to most, you, me and other traders.
You have to take risks in spec shares but calculated ones and move fast if you have to if things turn bad especially near a top.
Everyone has to take responsibility for their own actions and test the information you receive. You have never won or lost until you sell. However if you sell quickly in a down-trend, the losses you would have made if you held longer are now actually profits because that money hasn't gone..
I don't pretend to be a guru and you and others probably know all this now, so good luck to you, me and all in this challenging world of trading..
