Your post says: "The block was 71300 shares, $144k @ an average price of $2, bought by 085 Scotia Pro? maybe".
Perhaps, this was the signal for others to follow suit and brought the SP to $2.25/s at the close (a decent +10% for the day, or ~+15% from the low a few days ago, a welcome reversal).
If the block (~$150k) was purchased by Scotia, then it would be interesting to find out if Scotia had any analyst's coverage and positive recommendations for ZEN. It would be a lot more interesting if they severely downgraded the stock, and then this buy.
