Investor protection through individual is the strategy that one utilizes to minimize loss.
Individual investors can protect themselves by purchasing only shares of businesses that they understand, or only those that remain calm through market volatility.
Company dividends are paid from after-tax profits, with the tax already deducted.
Therefore, shareholders are given some respite with a preferential tax rate of 15% on "qualified dividends" in the event of the company being domiciled in the United States.
Non-qualified dividends paid by other foreign companies or entities; for example, those receiving income derived from interest on bonds held by a mutual fund, are taxed at the regular and generally higher rate of income tax.
An individual investor may be protected by the strategy he uses in investment.
The strategy includes an appropriate price of the stocks or assets in the right time he enters.
It's hard to fix what "an appropriate price" is, and when it is appropriate because no one makes a purchase or a sale absolutely in his most favorable situation.
However, determination may be made when the price of such share or assets are "undervalued" comparing to its potentiality.
