It would be a “very poor idea” for Apple Inc. to invest in Tesla Inc., Berkshire Hathaway Inc. Chief Executive and legendary investor Warren Buffett told Fox Business on Thursday. Buffett also issued an indirect, mild rebuke to Tesla Chief Executive Elon Musk during an interview broadcast Thursday, saying in regards to Musk’s “funding secured” tweet that while anyone can misspeak, “if you misspeak, you correct it immediately.”And If you have a stock “trading like crazy,” minutes later “you say I misspoke when I said ‘funding secured,’ I meant to say I really think I can get funding, something of the sort,” Buffett said. Musk last week backtracked on plans to take Tesla TSLA, -0.61% private, a proposal aired Aug. 7 through the now infamous “funding secured” tweet, which has ignited scrutiny from the Securities and Exchange Commission.via
