Stocks Double

What are the undervalued stocks that I can buy now and which can double or triple the value of a sudden?
'M 18 years I'm looking at £ 3,000 and £ 10,000 to make it soon, at least 19 years. I'm always looking at options trading, but my brother recommended me to wait few years so you can learn more about them and expand my knowledge. I also would like to get the first experience in stock trading, then negotiating options. I am a firm believer in value investing and am looking for undervalued stocks to double or even triple in value. I would be grateful if you could recommend some. Thank you.
Options trading can be very risky without adequate knowledge. I suggest you invest in stocks because they are low-Penny risk, low investment and high profitability. But expert advice before investing. I use exchange of signals given by the following web site that is very reliable: trades.devhub.com www.penny stock awards
