The rally of SpaceX (SPCX) stock appears to be partly based on notes from Morgan Stanley and Goldman Sachs that may be overly bullish. Specifically, Morgan Stanley seems to be meaningfully underestimating the stock's valuation, while both investment banks could be overestimating its growth outlook. Meanwhile, SpaceX CEO Elon Musk recently announced a name change that could help the company in the short-to-medium term but may slightly undermine it over the longer term.
Overall, investors may want to consider buying Amazon (AMZN) stock instead of SpaceX's shares.
