With stocks sitting near all-time highs, some advisors are asking a tougher question: what happens if the ride turns bumpy? Passive flows, options activity, leveraged products and trend following funds can all amplify moves when momentum shifts, making sharp reversals more likely than calm markets suggest. Systematic trend following offers a rules-based answer. It stays invested while prices rise and trims exposure when trends break, replacing emotional decisions with a defined exit plan aimed at limiting deep losses. Some strategies spread across stocks, bonds and gold, leaning toward assets that are working and stepping aside from those that are not. The tradeoff is real, since signals can lag and fast rebounds can leave investors whipsawed. Pairing trend rules with simple habits like rebalancing winners, holding some cash and matching risk to time horizon can help keep portfolios resilient when sentiment changes.

Finsum: Systematic discipline will not predict the next downturn, but it can keep investors from improvising in the middle of one, and that may be the most valuable edge when markets feel invincible.
