RR stock (Rolls-Royce) bears may argue that despite the recent price target increase to 800p, the stock faces risks from potential volatility in the defense segment due to geopolitical uncertainties and budget reviews in the UK and US. Additionally, the stock's sharp rally may have already priced in much of the positive sentiment, leaving limited upside in the near term. A pullback to support levels around 700p could be expected if market conditions worsen or if upcoming trading updates fail to exceed expectations.
