a new round of bear I starts after property mkt had achieved a throwback (in chinese, 見頂後抽 or so-called小陽春).
usually, as what happened on our earth history in the past 8000 years (we dun have written history beyond 8000yrs), the rising slope of property mkt MUST perform a double top, 2nd top is higher or lower doesnt matter.
after every double top, the tumble is fast.
apply this theory on HK now(it must work, always work, almost guaranteed; sometimes prolonged/extended by gov't policies), we say it again:
property price down by 40 to 70%
70-80%樓價大跌, 是那些"扮"豪宅及高級獨立屋, 而非一般 4xx sqf to 8xx sqf 單位.
