TPG Telecom (ASX Market) has greatly increased since 2012, then from Aug 2016 had a sharp fall. Some people consider the management is strong, even if their business decisions are not always popular. I don't know if their decision to become the fourth mobile provider in Australia is good or bad (some other companies failed while trying this). But there could be an opportunity to buy into a company that was (and it may still be) a good company at a premium price. For long term, I think it may be good to buy at any price under $6 (maybe it may drop to $5.70 in the next days) with a stop loss of $5.50. For long term (perhaps 6 months), the target would be $8.30 or above. Another possibility would be to choose a stop loss of $4.90 and a target of $8.90
