Profited from Singapore's Living with Covid Policy

$SIA (C6L.SG)$ Bought SIA at around 5.05 in Aug 21 in anticipation of Singapore opening up its borders and allowing tourists and Singaporeans to travel overseas. Sold them at 5.57 in Oct 21 when Singapore announced the vaccinated travel lanes. Now shifting funds to buy China border re-opening plays like Macau casinos. However, recent news release from China indicated that China would not open their borders anytime soon. Thus, prepared to hold my Macau casino stocks till next year and accumulate more to average down whenever the price dropped due to new covid infections in Macau and China(especially Guangzhou) which is located next to macau and is the casinos' biggest customer base.
