It looks positive to me that John Nantes, a director of the company, is prepared to part with $688,000 to acquire more shares in TAU in an off-market transfer and increase his holding by 71.119% (to be precise).
That looks like a vote of confidence.
Now John, as a holder I very much appreciate that vote of confidence. One small quibble is I would much rather see you make the purchases on market next time. Then we might get a little bit of positive share price action. Having said that I compliment the parties concerned on the nimble footwork involved with this transaction.
The last market trade, on extremely thin volume, was at 18.5 cents. It is not clear whether John's purchase was made before of after the small trade at 18.5 cents. So it looks like John paid a premium of 16.2%.
This stock is tightly held and the management are big believers. I look forward to John's and the rest of management's confidence in this stock being validated in 2019 and beyond.
