Someone in another geothermal thread observed that there is a kind of cyclical behaviour in the share prices of the five geothermal stocks. At least one is rising every day. Last week it was GHT; on Thursday and Friday it was TEY; today it is PTR, GDY, and GRK (to a lesser extent). In my opinion it looks as though big players are taking positions, selling down periodically to keep a cap on prices.
