You should never have all your money in stocks. You should always have some allocation to bonds and cash. But just so we are clear on how bad a decision that would have been to be in stocks, if you had 100% of your money in stocks in May 2008, right before the crash, but didn't sell you'd be up 104% since then (6.2% annual return). Your money would have literally doubled in less than 10 years even if you had the worst timing ever for the 2008 crash. Think about that. And that's a strategy that only had money put in at the worst time and wasn't continuing to invest more money in as the market went way down. If you are investing into it all along on the way up, your returns were way better.
Actually from 2000 to 2017, the SP500 is up annualized at a 4.8% rate with dividends reinvested. This is with an extreme increase in the last few years with very high valuations.
I agree with the market timing thing but the conventional wisdom that "just put money in the market at ANY time" is concerning to me.
We are using metrics from the US market over the last 100 years or so.
How about the Japanese market? If you got in 1989, you'd still be at half today. Plenty of other markets throughout the world has been the same way.
Just because the USA had a great run for the last 100 years doesn't mean it will be the same returns.
America was the SUPERPOWER CREDITOR nation of the world that was UNTOUCHED by either WW1 and WW2 whereby it had basically a GREAT RUN that is likely unprecedented.
In the last 17 years we had literally two crashes, which would have really hurt the portfolio of someone even with a 3% withdrawal rate if they continued to take out at the bottom.
The markets are artificially inflated with ZIRP, QE and massive amounts of leverage that are UNPRECEDENTED in the history of the US market. We also have debt that is UNPRECEDENTED with huge liabilities at the local, state and federal levels.
GDP growth is largely at ALL TIME LOWS despite all of this money printing and huge deficits. We have an aging population that will collapse the Medicare and SS system.
We also have a Millenial generation that has a COLLEGE BUBBLE with >1.4 trillion in student loan debt whereby they can't buy homes easily after getting mostly worthless degrees. These millenials have significantly LOWER SALARIES than their parents after adjusting for inflation DESPITE huge college DEBTS.
We also have ridiculous levels of leverage in the RA market considering the borrowing metrics compared to 30 years ago.
Even Vanguard Boglehead's and Schiller are guess the market will increase approximately 4% on average over the next 10 years if we're lucky.

For instance, in my trust, we have a specialized TIAA money market account that gives a PROMISED 4% per year on average. This has been in line with the SP500 for the last 17 years and will probably outperform it in the next 10 years.
I believe in diversification of assets including REITS, International Index Funds, high paying money market accounts, Vanguard Total Stock Index (broader than SP500 with very low fees) and DRIP individual stocks like ATT.
