The 'Always Be Buying' (ABB) strategy, involving consistent purchasing of index funds like the S&P 500, Dow Jones, or NASDAQ at regular intervals (weekly, bi-weekly, monthly), is presented as a winning approach for passive investors.
"The strategy that I teach when it comes to investing your money as a passive investor, it's very simple. Passive investing is a very simple concept. You just follow a simple system that I call a b beep. Always be buying. If you're investing the S&P 500 into the Dow Jones into the NASDAQ, this is the way that you win. Always be buying. You buy every week, every two weeks, every month."
