Yeah, we've seen this type of facade before many times over with Fsnr. Smoke and mirror exhibition and then nothing to support it, so back down to the bottom again!
What you erroneously call 'manipulation' is called normal trading by experienced people in the stock market.
It might go down, it might stay up, it might go higher, or it might close unchanged. That is normal trading, based on bids, asks, and the trades.
How anyone could mistake trading on or between the bids and asks as 'manipulation', and that has at least a little experience in the markets is remarkable and questionable of the motive.
