We'll say it up front:
We don't see Trend Following as the "nemesis" of Buy & Hold.
In fact, for younger folks, who are still in the "accumulation phase" of their investing lives, Buy & Hold using Dollar Coast Averaging (learn more here) is not a bad way to go!
Why? Because a person with a longer time horizon can "afford" to weather the ups and downs of bad markets - and Dollar Cost Averaging allows them to systematically accumulate assets when times are both good & bad.
BUT, for anyone who is not in their accumulation phase (retired or heading there), Buy & Hold can be disastrous.
Example:
Let's take an unlucky couple, Monica & Chandler, who retired at age 59 in the early 2000's and kept their nest egg in the S&P 500 or a 60/40 Stock/Bond mix.
Well, from about 2000-2010, the S&P 500 ended up going nowhere, and even lost a bit depending on the starting point you pick.
So, Monica & Chandler got seriously hurt over the next decade where their nest egg actual lost money, since the S&P 500 didn't return it's "normal" 8-10% annual return.
And, to compound the issue for Monica & Chandler, if they were taking out the standard 4% to live on, they got truly crushed: a double whammy.
Plus, even more disastrous: they had to weather a 50%+ drawdown to boot in 2008! How many investors can weather that depth of loss?
So, the point is Buy & Hold can be disastrous for those of us trying to protect and grow our wealth - and just investing in a "broad based" index won't necessarily provide the protection of diversification.
But the good news for Monica & Chandler is they decided to use Trend Following and not only protected their wealth, but participated in some amazing trends during their first decade of retirement, including the massive run-up in Gold, which returned 300%+ from 2000-2010.
