Hello ElP,
Just checking the trades during the last 15 min. on Friday 16 May (long weekend in Canada, the magic weekend, a bit early this year, for planting your gardens with annuals... and then a killer frost comes). As you said it's amazing to see no baddies trying to pull down the SP with 100s trades.
Instead, more than 50% of the day volume happened during this period. Perhaps, you would have more detailed data, but on the macro scale I saw three trades, starting with 500s, then a whopping (relatively speaking) ~8000s, and some 3200s a few minutes before closing.
It would seems that there was no manipulation, and the usual "supply and demand" ruled for the day (or the baddies took off early for a long weekend?). An order of 8000 shares (only some $20k) is not huge order, but if the supply is tight then the buyer would have to pay the asking price. Hope that this trend would continue on Tuesday. Perhaps, the person behind the 8000 shares knew something was coming? Speculations, speculations,...
