Volatility Shock and Q4 2018 Selloff

The year opened with synchronized growth hopes but quickly met a volatility shock in February as inverse VIX strategies imploded. Later, a mix of tighter financial conditions, trade tensions, and slowing global data culminated in a Q4 selloff. The S&P 500 fell nearly 20 percent from highs into Christmas Eve. Credit spreads widened, with high yield underperforming as issuance windows narrowed. The 10-year Treasury yield, after peaking above 3.2 percent, fell back as growth fears mounted.

Market internals deteriorated. Breadth thinned, cyclicals lagged defensives, and liquidity in credit grew patchy. Earnings revisions turned negative while guidance flagged input costs and tariffs. The Fed signaled data dependence but had tightened materially. We saw higher hurdle rates for risk assets until policy and growth clarity improved. The balance of risks argued for quality, liquidity, and patience over tactical bravado.

In client portfolios we reduced exposure to late-cycle beneficiaries and added duration to stabilize volatility. We raised cash to opportunistically buy durable franchises at better prices. Factor tilts moved toward quality and minimum volatility, while we pared small-cap and leveraged balance-sheet risk. We maintained commodity underweights, anticipating slower industrial demand and improved supply discipline ahead.

We entered year-end with a plan for staged redeployment tied to policy communication and earnings season. We stressed liquidity management, avoiding crowded credit. Hedging used index options with defined costs rather than open-ended shorts. Our stance preserved capital into the trough and kept us prepared to add risk on credible policy recalibration.
