Contact your 2 brokerages and find out which department ( if I remember at fidelity it's the secured lending department?). That Loans out equities. They have you sign a few pages That is it . No risk to you You can sell your shares whenever and as you would normally do They do the rest and pay you once a month
The brokerage is using your shares to fill loan requests ( shorters) They will find someone else's shares to loan so why not take advantage And make money for yourself
Now depending on how hot an issue you own -- the rate of % varies For example Nak apparently is not being shorted now And the % rate is very loan (2.75%)
When NAK goes up soon I expect the shorts to jump in And the % rate offered will be higher ( I'm not planning to keep it ) That's how it works
I have another stock that is paying 28% to borrow
The brokerage looks at your account and will use any equities they can make money with
