Beta is a measure used in finance to understand how much a particular investment moves compared to the overall market. It helps investors assess the risk and volatility of an asset. A beta of 1 means the investment moves in line with the market. A beta higher than 1 means it tends to be more volatile, while a beta lower than 1 means it's less volatile. A negative beta means the investment moves in the opposite direction of the market. Beta is used to manage risk and make decisions about diversifying investments.

Blockage discount is a reduction in the value of a large number of shares or a significant ownership stake in a company when selling them all at once could disrupt the market. It accounts for the difficulty of finding buyers for such a big block of shares without causing a negative impact on the share price. The discount is applied to the value of the shares to reflect this potential market impact and provide a fair valuation. Blockage discounts are used when a large shareholder wants to sell a substantial number of shares, and they help establish a more realistic value for the shares considering the challenges of selling them in bulk.
