Twitter CEO Jack Dorsey purchased sevn million worth of Twitter shares earlier this week.

The purchase of the shares sends a signal to the market that he’s confident in the prospects of the firm he runs.

However, the purchase has also sent a much clearer signal to the market: that nobody is interested in acquiring Twitter (he couldn’t purchase shares otherwise), removing a floor on the stock present since they announced they were courting suitors last year.

D’oh!
