| Insider transactions show you what executives, directors and major shareholders do with their own stock: people who know the company from the inside. Buys are the most telling signal, because insiders invest their own money. Sells are harder to read, since they can also be driven by taxes, diversification or expiring option programs. |
| Short interest shows what share of a stock's freely tradable shares (float) is currently sold short, meaning held by investors betting on falling prices. A high or rising level can be read two ways: it reflects the skepticism of many market participants, but also carries upside potential. Because if the stock rises, short sellers have to buy back, which can push the price up even further. This effect is called a short squeeze. | |
| The short interest in Twist Bioscience Corp. has held steady at around 23.8% of the float over the past 12 months. Short sellers' positioning has barely changed in this period. |
