plaything

I'm a longterm holder of Straits and its been good to me and to the extent I bought some more a few weeks ago.

I keep an eye on trading and am bemused by what I see as the inconsistent trading. Up and down, low turnover or high turnover, it doesn't seem to matter. And than there are the comparatively big SP drops on miniscule turnover.
I don't think it is bot activity but could be wrong.

Anyway of late SRQ just seems to be plaything for someone, but no doubt with a plan in mind. I'd like to know what others think.
