The first time was a distributed limit order, all got filled. The position was quite large, and I took profit early. Focused on short-term moves rather than a trend rebound—couldn’t hold on with such a big position. Let’s talk about the characteristics of these moves: the first rebound was the strongest, reaching 1950; the second only went to 1650; by the third, I said I wouldn’t touch it at 1500 anymore and would look at May’s support levels instead. These rebounds in Sandisk perfectly illustrate the classic pattern of 'rise with vigor, weaken the second time, and exhaust by the third' from *Cao Gui’s Discourse on War*.
