Stock Market Investment Act

Stock Market Investment Act - Amends the Internal Revenue Code to permit an income tax deduction in the amount of dividends paid by a corporation. Disallows such a deduction by S corporations, regulated investment companies, real estate investment trusts, and personal holding companies.

Repeals the income tax deductions currently permitted in connection with: (1) dividends received by a corporation; (2) dividends received by a corporation on the preferred stock of a public utility; and (3) dividends paid by a public utility on its preferred stock.

Increases from 80 percent to 85 percent the deductible percentage of amounts received by a corporation from a qualified ten-percent owned foreign corporation.
