TOWER shares have consistently performed well since the arrival of its new corporate heavyweights on the share register and Jim Minto at the helm. Attentive readers might recall that I bought a few hundred shares when they were really, really low, as an example of performing a share trade online. Now I wish I had bought more. A recent article highlights a substantial rise over the last few weeks which has little corporate news to support it. It is obviously fuelling speculation.
