If you insist on other people doing your research for you then I'll oblige this once.

The picture is quite clear from KRC's chart, especially on very low volume days as depicted below where bots can offload minimal amounts of shares (often 1 share unit) to have a material impact on the SP.

If you've watched the action over the last week you'll notice that the SP was being ticked down whenever a lesser price was present on the bid. The SP has dropped by a whole cent over the last week, and bots have played a role in this. Lack of newsflow and volume means bots can suppress the SP and work to diminish confidence in a stock, also triggering stop losses on the way down.

I'm not particularly phased by this, but it can get annoying at times. It's also worth remembering that when a stock is moving up, bots are also there accumulating so it works both ways.
