But building a diversified portfolio of individual stocks takes a lot of time, patience and research. The alternative is a mutual fund, the aforementioned ETF or an index fund. These hold a basket of investments, so you’re automatically diversified. An S&P 500 ETF, for example, would aim to mirror the performance of the S&P 500 by investing in the 500 companies in that index.

History shows that investing in stocks is one of the most profitable ways to build wealth over the long term. Nearly every member of the Forbes 400 list of the wealthiest Americans got there because they own a large block of shares in a public or private corporation. Learning to invest wisely and with patience over a lifetime can yield a portfolio far outpacing the most modest income.
Over the long run, value stocks outperform growth, so look for stocks trading at relatively cheap valuations based on price-to-earnings ratio (P/E), price-to-sales ratio (P/S), and price-to-free-cash-flow ratio (P/FCF). It is vital not to chase opportunities, but rather wait for them because patience always pays. Solid fundamentals and a large moat (barrier to entry) are also vital for long-term sustained success. Also, use technical analysis and charting to better help pinpoint both the entry and exit points for the stock under consideration—both for a target profit area and a stop loss.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
