The chart beside it

Price +0.6% vs its 50-day average, +30.5% vs its 200-day, -8.8% from its 52-week high. Next 5 sessions: bargain $159.99 (-6.3%), stretch $182.19 (+6.7%). 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.

Insiders

No insider buys or sales on record for GH.

Officers, directors and 10% owners file SEC Form 4 within two business days. Unplanned: the insider chose to trade now, the trades worth attention; their dollars make the net above. 10b5-1 plan: scheduled in advance, kept for the record. Tax: shares withheld on vesting stock, not a market trade. Awards, option exercises and gifts are left out. Source: SEC EDGAR, collected daily for the stocks discussed on Reddit.

Share of ARK: the stock's value over all of ARK's ETFs added up, from their daily holdings. From trading: the net dollars ARK bought (+) or sold (−) over the window's average assets, in points; from price and other: the rest of the change, mostly the stock's price against ARK's other holdings. A run: ARK trading the stock the same way with at most two sessions between trades (ARK spreads large orders out). This describes ARK's flow, not the price: in our check of 2020–2026, stocks trailed QQQ by about 3% over the 60 sessions after ARK's buys, and did about as well as QQQ after its sales.
