PureTech Health (LSE:PRTC) represent a fairly apt focus for discussion, following a flurry of visits to our local GP’s in-house vampire, a lovely lady called Fiona who regards it as her life work to extract blood from the innocent.  

PureTech claims to have an orally administered weight-loss solution. In our book, any initiative which does not involve injections deserves extremely positive attention.

The company boasts a share price which has been waffling around since breaking the closing price downtrend from 2021, the price carefully respecting this historical downtrend and building hope for the future. Perhaps their half-year results announcement on 22 September is supposed to cause a sharp surge upward.

If we’re right – and we expect to be – above just 129p should mean reaching an initial 133p with our secondary, if bettered, at a comfortable 140.5p. This secondary target level is liable to prove important, launching the share price into a zone where a long-term third level ambition of 162p makes some sense. Visually, this is our expectation.

Should things decide to go wrong, below 113p should apparently trigger reversals to an initial 109p with our secondary, if broken, at 102p. And perhaps a solid bounce.
