Oh, for sure - bottom fishing is usually a bad idea. But once in a while I just have to try it. There's some strange appeal for me. Regardless, since I bought at 7.22 with a stop at 6.94, my risk is small (barring a large gap down).
I know of no way to reliably sell a parabolic move near the top. I just sell parts of anything whenever I sense a short term top. SMF looks fantastic - I suspect it has a lot further to run. Had a parabolic run in 95-96 & looks like it wants to do it again. Only resistance on this is from investors who bought that parabolic run and are still holding. There can't be too many people in that category, so not much resistance at all.
