Haha, that kind of movement doesn't hurt whatsoever when you're a long-term investor. If I were a short-term trader; the likes of which would consult archetypal price graphs as you did to assess value instead of analysing the fundamentals of the underlying asset, the company itself, to assess value; then I'm sure it would hurt. But, as it stands, the story hasn't changed and, so, as a long-term investor, it doesn't even tickle. Trot on.
