Leveraging is a relatively risky method, but luckily his inner monologue helps him avoid such risks.
Simply put, you only need to remember one thing: although the market will show a significant upward trend within forty days, there will be declines during this period, and he only needs to avoid those phases where the drop exceeds ten percent.
Because his principal is only 10 million, but with ten times the leverage, it's equivalent to trading stocks with one hundred million. However, his ability to bear risk hasn't changed; it's still 10 million, and due to the characteristics of forced liquidation, he will bear even greater risks.
If not leveraging, he could just buy a stock and wait to sell within the specified time, without worrying about the market fluctuations during that period.
Anyway, it's just an increase in his workload.
