<human>:  Can you tell me about some of the best investment strategies for beginners?
<bot>: As a beginner investor, it is important to diversify your portfolio to reduce risk and maximize returns. One of the best investment strategies for beginners is to invest in a diversified portfolio of index funds, which typically provide a lower overall risk than investing in individual stocks. Another effective strategy for novice investors is to practice dollar-cost averaging, which entails investing a set amount of money into the stock market on a regular basis. Doing so reduces the risk of entering the market at a high point, as well as helps to build a portfolio's overall value. Additionally, many successful investors recommend “buying and holding” stocks over a long period of time, as this can produce good returns and reduce transaction costs.
