That's a 30% gain, which is not unreasonable considering the market (NASDAQ specifically) has averaged about 20% per year.
If you wisely invest your money in stocks, while controlling your natural greed & fear emotions, a 30% gain is very much achievable - especially when compounding your gains.
Now, as to which specific stocks to invest in - well that changes based on each very second in the market. Generally, investing in undervalued companies are the best opportunities, however there are other factors to consider before entering a position.
Too Huge Desire!!
