some ppl say that she speculates in copper futures... but it is not clear where her seed money came from...
this gal is rich. The news article confirms that she has spent millions purchasing companies/properties in the last few mths. However, it is unclear how much she has. It is said that she has 2-4B RMB (USD500M).
if she made 500mln from 8mln than it's possible with leveraged trades and in copper even more likely.
according to one study, most traders lose because they kept trading after they have met their target. (either daily target, mental target, or percentage target, etc.)
