The reiteration of the 'Sector Perform' rating and maintenance of the $3 price target by RBC Capital suggests a neutral outlook on BlackBerry's stock in the short term. This indicates that the analyst sees the company as adequately valued at its current price level, without immediate catalysts for significant price movement. Therefore, the impact on the stock price is likely to be neutral in the short term, as the market has likely already priced in the analyst's expectations.
