sdi touches $10, what about cst ?

I've followed these two for a while. SDI would now be close to a "ten-bagger", but of course I sold out too early! Valuation still over-stretched IMHO, and yet it continues onwards and upwards.

Nevertheless, SDI shows what can be achieved with a suite of good products developed from in-house R+D and out there in the market place.

In the time SDI's share price has increased 1,000% CST has gone sideways. .....can they get a product up ? Will a single product be sufficient for them to be the next SDI ? Still being priced on hope and expectation in my view.
