The chart beside it

Price -15.5% vs its 50-day average, +44.3% vs its 200-day, -37.1% from its 52-week high. Next 5 sessions: bargain $108.91 (-15.6%), stretch $152.90 (+18.5%). 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 TWST.

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.

Congress

No congressional trades in TWST on record.

Members of Congress report trades within 45 days of the trade date, so these are never real-time. Amounts are disclosed as ranges; the net uses each range's midpoint (≈). Source: House and Senate periodic transaction reports via CongressInvests, refreshed daily.

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.
