How low can this go?

I've shown this particular UK stock a couple of times prior to this, but it just goes to show that, when  a trend takes off, you are best to stay in for the ride until the trend finishes. This is a dreadful chart if you are an investor, a beautiful chart if you're a trader, and one the reasons why I advocate that investors also refer to a trend following method (albeit a longer term one than the system I use) so that they never knowingly overstay their welcome. There is no knowing how much further this will fall...
