In addition, for the main investment targets, I will use a step-by-step approach to add and reduce positions. Taking N2IU as an example, assuming my benchmark stock quantity is 0.1 million shares, when the price falls, I will buy in batches in increments of 0.02 million shares, up to a maximum of 0.16 million shares. Once it exceeds the target price, I will reduce positions in batches, but I will always keep a minimum of 0.06 million shares. This way, it may result in slightly less profit during price increases, but it will also reduce some losses during price drops and avoid being caught empty-handed in case of a sustained rally.
