Analyst downgrades typically lead to a negative short-term reaction in the stock price as market participants adjust their expectations based on the new analyst outlook. The downgrade from 'Outperform' to 'Neutral' suggests a less optimistic view on Tesla's near-term growth or valuation prospects, which could lead to selling pressure. The setting of a price target of $195, depending on its relation to the current trading price, could also influence investor perception and stock price movement.
