The irs regulations wont allow itthey are always treated as capital gain and do not count towards your social security.
No.
Only earned income is counted towards SS benefits.
I know, you earned the trading profit, but that’s the way the IRS defines it.
If you declare yourself as a fulltime stock trader, then yes, you may. BUT - you have to pay both the employer & employee portions of Social security tax, PLUS medicare tax.
Unless you are a very successful trader, you probably don’t make enough to justify claiming your trading profit as earned income.
