Nvidia reported revenue that barely exceeded Wall Street’s expectations, triggering an 8.5% stock slide as investors hoped for more outperformance. But Bank of America said that Nvidia is still a solid investment and raised its price target 5%.

Such a move would shift about $300 billion in market value and send Nvidia shares plunging to $117 or soaring to $143.

Why Nvidia’s longer-term future return is not worth the risk — even if it continues to be a phenomenally profitable company. Nvidia Corp.’s market performance over the past six months is a good illustration of the difference between a good company and a good stock.
