Oil analysts have raised their average price forecasts for 2016 for the first time in 10 months, but cautioned that investor sentiment may sour short-term without solid improvement in market fundamentals, a Reuters poll showed. The oil price has risen by about 45 percent from 12-year lows close to $27 a barrel reached in January. “The recent rally is more a comeback from very bearish sentiment that took place at the beginning of the year with China headlines, Iran sanctions lifted, reasons that we actually found to be an irrational move of the market,” Raymond James analyst Luana Siegfried said.
