Tesla’s unsolicited B Minus rating from Standard&Poor’s means it rubs shoulders with Greece, Congo, Egypt, Jamaica, Pakistan. Sounds like bad news. But here’s some good news. You don’t make money by owning AAA-rated companies. You pick companies with growth potential and stomach the risk. The S&P told everyone to sell TSLA last October at $183, so the agency ranks among the many stiff-suited nincompoops that can’t really wrap their heads around Tesla anyway. UPDATE: A today’s close, Tesla lost a whole 0.62% for the day. A muted market response, if any.
