SAS Revenue Announcement, page-90

I think you're confusing a ruthless stock market with the local happy go lucky Sunday church picnic where nuns gather. It's meant to be a savage game where buy and sell decision are made for self-gain rather than the overall wellbeing of other holders. That's the nature of money.

Not everyone is at liberty to practice long term holds, that's why we have day traders that rely on those small pips for their weekly income. It's a style of trading different to your own which apparently you have a pretense about when characterising it as pety tactics.

What you may not consider a big impact on the SP from an announcement increasing movement by a couple cents, it may be a huge difference for someone else. Be respectful and get off your moral high horse.
