Definition of 'Anchoring'
The use of irrelevant information as a reference for evaluating or
estimating some unknown value or information. When anchoring, people base
decisions or estimates on events or values known to them, even though these
facts may have no bearing on the actual event or value.

Investopedia explains 'Anchoring'
Here's an everyday example: a friend asks how much you pay in rent for your
800-square-foot apartment, and then asks how much a 1,100-sq-ft apartment
would cost to rent in the same building. Would you make an estimate by
adding a little more to what you pay even if you've no idea of the actual
costs? If so, you would be anchoring your estimate onto what you pay for
your apartment.
In the context of investing, investors will tend to hang on to losing
investments by waiting for the investment to break even at the price at
which it was purchased. Thus, they anchor the value of their investment to
the value it once had, and instead of selling it to realize the loss, they
take on greater risk by holding it in the hopes it will go back up to its
purchase price.
