skc, my TA knowledge lacks quite a bit but from looking at TGA's chart it looks like its in a downtrend from approx 4/4/2011 through to now and. . .
I have never understood the rationale for TA, and I have presumed that the wiggles in the graphs are useful in that they reflect the collective thinking of Mr Market. Whether it can usefully inform us what the market is thinking about a tending-to-be illiquid (about $600K a day), micro-cap (less than ($300m) that is relatively tightly held (about half a dozen shareholdes own 60% of the shares), I cannot say, but I suspect not.
For reasons that often make little sense, instos like Perpetual and IOOF may decide to sell a few million dollars of TGA, and this smashes the SP, whereas if it were WOW, that selling pressure is massively muted by the millions that others transact every day. I suspect that TA is not suited to make much sense of this, but, as I wrote, I do not know.
Fundamentally, nothing significantly has gone awry with TGA's business. I wish the SP would stay down at circa $1.50 to allow me to garner the funds to buy another 30,000.
