Time to sell HSI Calls and buy HSI puts.   Puts have so far not reacted much to falling HSI while calls are making the volatility.
The logic must prevail, when index is up, buy call and when index is coming down buy puts.   Yes! Yes! Yes!! (Copying Daniel Brians) Hahaha!! 
Hang Seng market looks bullish.   Buy structured warrants (HSI warrants) for better profits.   Very fast one as you need to be quick in and quick out.
Calls warrants are very proactive. Whenever HSI goes up, HSI-Call W will spike.   When HSI comes down, the puts will go up.  
Notice however, that puts are more laggard to go up when HongKong index is down,   so better buy call warrants, and short put warrants when HK market goes up.
