Quantitative Analysis

<ul>
<li>On average, the HSI lost 1.1% (since 2013) and 2.8% (since 2019) in Oct. The worst drop was 2022 with a 14.7% plunge, and the second-worst is 10.1% in 2018.</li>
<li>If HSI settles at 1SD lower than the historical average Oct return, it will translate into return of -7.5%, and if 2SD, it will be -14%.</li>
<li>A weak Oct sets the strong stage for Nov and Dec, which are historically best months. Picking up when the market retreats looks to be sensible.</li>
