The reiteration of a 'Buy' rating by a reputable analyst like Rajvindra Gill from Needham is a positive signal for investors. It suggests that the analyst believes the company's stock is expected to outperform the market or its sector in the short term. The maintained price target of $2.4 also indicates that the analyst believes the stock is currently undervalued, which could lead to an increase in the stock's price as the market adjusts to this information.
