Targeting mostly men. People interested in penny stock tips, stock tips in general, making money in the stock market etc.
Use anything related to stock market (i.e. bull, tickers...use your imagination) Maybe incorporate explosion some how? Dynamite? A fusebox? Use the colors from the website in the logo creation http://www.pennystockexplosion.com.
When people see the logo I want the "WOW what a cool logo" feel.
Have at it...be creative and think outside the box ;~)
