Most the investing establishment considers buy and hold investing the Holy Grail that always works out in the long term. For long term buy and hold investing your entry time frame matters, whether you got in at good prices and if you have time after bear markets to get back to even. NASDAQ buy and holders waited a long time from March of 2000 and buy and holders from 2007 also had to wait many years to get back to where they were. The most simple long term moving average systems can beat buy and hold by getting and keeping you in during bull markets and getting you out before big drawdowns. You are capping your downside risk and keeping your upside potential profits open by simply having an entry and exit strategy based on price action not opinions or predictions.
