Investopedia explains 'Overwriting'
The writer of an option has an obligation to perform a certain action, while the holder of the option is not obligated to perform any action. Overwriting is a technique used by speculative option writers to attempt to profit from the premiums paid by option buyers for option contracts the writer hopes will simply expire without being exercised. Because the holder could exercise the option, this strategy is considered risky and should only be attempted by those with a comprehensive understanding of options and options strategies.
