This is silly.
It was not 300 shares it was 350 shares. And in fact it was the odd lot remainder of an overall 9350 buy. The board lots went through at the limit price and the odd lot of 350 didn't fill immediately. So the buyer likely went and changed the limit price to a market order attempting to fill the remaining balance of the trade not realizing the gap in the bid/ask on this illiquid stock.
The trade has since been busted which tells you it was an error.
Your theory:
An investor decided to overpay 10x the market price by using $99 of ammunition to "manipulate" the stock price up for perhaps ... 20 minutes?? Right up until the next trade brought the stock price back immediately back in line to trending price.
So, what exactly was the point, in your words, of this manipulation scheme? To move the price for 20 minutes?

Just you, the self appointed board moderator. The truth is, I've been holding my tongue reading your brilliant analysis of the numbers ...
