I am not much experienced in the stock market...
Someone have some undervalued stocks with huge dividends, which are not well known?
Do not invest in stocks. Never invest in something you do no understand,
I agree. This being said, the problem with stocks with huge dividends is that they are much riskier than stocks with average dividends, and they usually end up cutting down dividends or even ceasing to pay them at all. Dividends are not the only thing you should look when buying stocks, you should also look at debt, recent and projected growth, competitive advantages, rations such as P/E, and, most importantly, free cash flow and free cash flow growth in the recent years.
