The past week's bullish calls included the electric vehicle leader and a prominent IPO. Short sellers were behind some of the bearish calls seen during the week. The Dow Jones industrial average crossed above 34,000 for the first time last week, as strong results from big banks kicked off the first-quarter earnings reporting season. Optimism also was boosted by good economic data, a steady Treasury yield and reassuring words from Federal Reserve Chair Jay Powell. All of this muted the impact of bad vaccine news early in the week. The week also saw the largest direct listing in history, Jeff Bezos' final shareholder letter as CEO and news of the much anticipated next big event from the iPhone maker.
