There are four golden rules every investor should keep in mind, regardless of income or investment knowledge, CNBC's Jim Cramer explained during his daily "Mad Money" show Wednesday.
Many investors are leery of OTC, or over-the-counter, stocks – and there are plenty of good reasons for that caution. OTC stocks often involve companies too small to be listed and traded on the coventional and better-known stock exchanges.
For many, stocks listed on the Pink Open Market are to be avoided, as it is often regarded as the province of thinly-traded, poorly capitalized firms that could not qualify to be listed on "The Big Board" or other, more reputable exchanges.
