no reasonable person would derive that from my post. But let me make it very clear for you. Transaction related costs in the region of 0.22% put a relatively small dent into the book of someone who trades high beta stocks such as Tencent which often trades several hundred basis points intraday.
That is derived implicitly from your post. If he makes on average just 0.5% a day then the stocks moving 5% a day should be irrelevant for all practical purposes.
