I hold because it sits under my current valuation based on what I under my current valuation of the business based on the research I have done. I'm confident in my valuation, but I've also see how overhang like this one now has will impact share price. Doesn't really matter me what the price does in the short term as long as the valuation doesn't change.

I'm a pretty dumb investor; every time I try to time the market I get it wrong. I'll be boring and just sit on my hands for now.

They've been rightfully smacked around post the results, but as a generally rule if the valuation is intact I don't sell just because investors are in pain.
