The chart beside it

Technical rating: Strong Sell (0 buy, 10 neutral, 16 sell of 26 indicators). RSI 29. Price -29.0% vs its 50-day average, -6.6% vs its 200-day, -45.8% from its 52-week high. Next 5 sessions: bargain $148.83 (-13.2%), stretch $197.41 (+15.2%). Technical · Pricing

Everyone we follow who traded the stock in the past 90 days, the runs still going first. Public: the day the trade became known (ARK's the evening of each session, a Form 4 or 13F on its filing day, Congress's on its report); price since: from that day's close to the latest. Price vs theirs: the latest price against the average they paid or got (a 13F's is the quarter-end price). Of the float: the shares traded over the shares the public can trade; their stake: shares held over all shares outstanding (a manager's: its last 13F plus its Form 4 runs since, ≈). Insiders: unplanned trades only (open-market buys, sales outside a 10b5-1 plan). 13F values are at the quarter's end and the trades happened some time in the quarter. The technical rating and bargain / stretch prices are the Technical and Pricing tabs' own. These describe the flow, not a forecast.
