How does a short squeeze work against Materialise? A short squeeze for Materialise occurs when it has a large amount of short interest and its stock appreciates in price.

A high number may indicate bearish sentiment.Short Float: The percentage of a company’s publicly available shares (or "float") that are sold short. A higher short float suggests a greater portion of the stock is being bet against.Days to Cover (Short Interest Ratio): This estimates how many days it would take short sellers to cover their positions, based on average daily trading volume. Higher values can signal potential for a short squeeze if buying pressure increases.These metrics are often used by traders to gauge sentiment, volatility risk, and the potential for price movements based on short covering activity.
