As noticed in the daily relative strength chart (against BETXT) above, TGN overperformance broke its uptrends following a year long of consistently beating the index.
The short term trend is clearly down and the technical damage is increasing the probability of a longer term underperformance cycle.
Cash-basis, TGN's longer term first support is in the 225 - 235 area (as noticed in the weekly chart above). Holding above this area keeps the probability of the stock tilted towards the long side.
Using a P&F chart (above) we identify the 215 level under which the uptrend starting in 2009 is probably reversed.
