It's not a recommendation but my realistic timeframe is maximum 18 till 24 months. But any huge event can trigger DTS SP to reach those levels before.
My cost average is 15.32c I understood that bellow 20c is a bargain and I bought a lot averaging down @13.5c.
With DTS I believe patience will be rewarded. They're doing great work, If I had now more money, I would keep buying. IMHO, not a recommendation!!!!!!!!
Good luck Stu!
