五月股票期權倉（月結）(被)極限施壓

Logbook 實在太長本熊都係直接講結果：

TSLA -0.16%
175 -7.84%
17 -2.37%
AAPL -9.0%
5 -0.98%
NTNX -1.35%
BABA -6.32%
2318 -0.80%
700 -5.52%

Total -34.34%

簡單黎講一至四月贏番黎果啲一次過輸番矖出去，連同正股都一野回到解放前，FY19 仍然係正數都離負方不遠了。

五月接左一倍貨番黎，令到持貨總額達到歷史最高點，槓桿水平也去到2.11 的危險水平。故六月操作首要任務係降低持倉，逢高 (啲啲都好) short call 放番啲貨走；若放唔走就一直降低成本，就像阿爺咁打算打持久戰的想法。

六月係敗者復活還是萬刧不復呢？希望好快就有答案...

五月結算：-34.34% (回報已包括交易成本） 六月啲權未平倉的唔計住（因以前mark to market 有可能計多又有可能計少，若要準確要分兩期入數，倒不如抽走在結算月一拼計算。
