At this point Microstrategy announcing they bought more BTC is about as relevant an announcement that I am about to go out and buy breakfast.
It's what they do. And if the price goes up enough they will sell them, and if the price then drops after that they will buy more. And keep the difference as profits.
That is more or less their business. Not saying it's good or bad, just they have shown that they are going to keep buying a lot and occasionally selling. At this point they are probably not really that important an indicator of future price sine they do keep buying and selling. It's not that rare an event.

Actually they sold only once if I'm not mistaken, and they did it at the wrong time, but it was a necessary measure. And the rest of the time they are buying and you are right, they are buying absolutely at all levels and in any markets.
I watched an interview with Sailor, the bottom line is that he believes in bitcoin at 500k and above, so they are not afraid to dig at any price. By the way, despite their purchases at different times, their average purchase price is around 30k, which is a very good indicator in the run-up to the bull market.
