The position has reached 70%. If there is a particularly big market trend in the future, I might be constrained by Novo Nordisk. I can't bear to sell at a loss. Before buying it, I looked at its dividends. If it falls a lot, I'll keep it to collect dividends. The position is very small and allocated extremely precisely. Also, TSLG's advantage is that it's suitable for small capital to gradually build a position, using leverage to slowly grow one's capital pool. I entered the position in three batches: bought 5 at 7.2, bought 20 at 7.0. I found that a double position size needs at least 20 to let small profits offset tuition fees ^_^. Doubling is not a monstrous beast; manage your capital well and don't be greedy.
