Stocks that do not have a proven track record of steady pay back or build up

Invest in blue chip stocks.

Blue Chip stocks are the largest companies in the stock market, typically the companies in the Dow Jones index and similars. They are supposed to be stable and high-quality, while speculative stocks have a high probability of moving a lot in price either up or down, like prospecting mining companies, high technology companies, and similars.
