Hey, I am aussie bloke, with a couple of years experience, investing, researching and of course experimenting within the Australian stock market. From this experience I can confidently conclude that passive investing is the best approach for me and I would strongly recommend this Investing strategy for the vast majority of investors in the world.

My approach to passive investing is to "Dollar Cost Average" into a variety of ETF's(Exchange Traded Funds) that cover the whole market. Depending on your income(how much you can save), I have created a few different portfolios each covering the whole market. The portfolios with more stocks come with many benefits which can be seen in each individual portfolio summary, but come with a trade off, being the more stocks to invest in the larger the time period between investing in each individual stock, thus decreasing the benefit from "Dollar Cost Averaging". For Example, For a $1000 dollar investment every month For 1 ETF Portfolio, then you are investing in that ETF every month, meaning the buy price volatility of the ETF is averaged every month or 12 times a year. For a 2 ETF Portfolio, if investing in an equal weighting distribution, each stock is bought every 2 months, this still averages out the volatility in the ETF price, but obviously not as well as monthly purchasing, as the ETF value can change a reasonable amount within 2 months. Each persons situation is different, and obviously if your income is higher, you will likely invest more often, thus the time period between investments will be less, and thus the benefits of a larger ETF portfolio is much greater then it would be for a lower income individuals. Another key aspect to consider is your risk tolerance, ETF's in general are already the right choice to minimise risk. But as previously mentioned another risk management technique is to "Dollar Cost average". Of which the more often the stock is purchased the better the risk reduction, as the volatility in the ETF's purchase price is averaged over more points throughout the year. For frequency of investment calculation I recommend and personally use this calculator, https://investcalc.github.io/, at a 8% return. Then the delay of purchasing each ETF is 100/weighting x Time between investing, (for risk evaluation).
