*  The future is unknowable
*  Compounding interest is how investing works

Early in your investing life there is no chance of much danger, as the balances are small and relatively benign in how much damage they can do to your life overall. So we might as well take all the risks we can.

As we approach retirement, especially that last decade or so is when all the real gains happen. with 6% growth your money will double in 13 years. So that last doubling will be HUGE for your retirement income as you go to retire. This leads to discussing volatility.


If we are invested 100% in equities, say a nice boring total stock market index(like VT), we will notice that history teaches us we can have a decade of terrible or no growth, but that is usually followed by tremendous growth of double digit % real growth.

Volatility sucks


see Economy

So we need to keep our sustained growth rate nice and awesome forever. How do we do that?

Diversification across all asset classes.

So how about we just buy every asset class at "global market cap rate". i.e. we just buy a piece of everything, so that when X does well, we own some. when Y does well, we own some.

Asset Classes

Active investing.

The professional "active investors" generally lose money after fees are taken into account:

"When performance is measured using before-fee model alphas and compared across the cross-sectional distribution, any active fund performance advantage is substantially less than one would conclude from benchmarking to average index fund performance. Moreover, any advantage of the top active managers over the top index funds is much less than the advantage of the worst index funds over the worst active funds. When performance accounts for residual risk, active funds no longer outperform index funds. " - Passive versus Active Fund Performance: Do Index Funds Have Skill?
