In this case it was very clear that there was a large sell in the system with Tuesday's trades showing buys exceeding sells yet with the SP off by over 10%
We can only guess the reason for the sell but someone shrewd or connected enough to have an inside line on activity in Kaz is unlikely to sell in one trade because they'd also know it would crash the price. Much more likely a leveraged position elsewhere getting exposed imho
Although it's none of your business, as I have said before I am a holder here. I just call out obvious bull**** like "deal done, just dotting i's and crossing t-s" or "it's definitely something to do with Vela/AAA" or "it'll be smarttech247" when that company had already announced an IPO or "the confirmation statement has just been filed it means the rto is done" or... and this was today's classic... " they own 100 planes so have assets of £1.4bn"
If you have a problem with any of that then frankly I couldn't give one
