LOCk your shares!!! It's no joke! with a GTC sell order at a much higher price to keep them from being borrowed by shorters or market makers from your broker. They are your shares, don't let your broker lend them out.
Also Turn off any opt in share lending options in your broker account, I know internation brokers will let you earn interest by lending your shares to shorters for example.
