&gt; Is there any indication that these wild swings are caused on purpose? I mean they did occur after the Chinese devalued their currency again, so did they not know that a downturn in the market was going to follow?<p>I am a Chinese and I heard two theories from my friends:<p>1. Today&#x27;s swing is a response to North Korea&#x27;s hydrogen bomb news.
2. The downturn in the market is deliberate so that China&#x27;s pension fund, currently in massive deficit, can reap the gains by entering the market at its low point.
