As with any swing in the market, the aftermath of a correction presents an opportunity to reevaluate and rebalance. Granted it can be quite painful for your portfolio, but there’s no denying that losing money is a good way to learn a lesson sometimes; after all, investing is a lifelong learning process.

As stocks pushed their way down on Black Monday, August 2015 was propelled into the stock market “Hall of Shame”. Perhaps that’s a little harsh, but regardless, it’s hard for your jaw not to drop when you see the volatility index (“fear gauge”) VIX spike from 12 to 53, and the S&P 500 ETF (SPY A) shed upwards of 6%, over the course of a single month. We’ve all heard of the summer slump…but this felt more like a massacre.

The table compiled below showcases some obvious, but nonetheless noteworthy, surprising ETF portfolio returns.

Key Takeaways

Let’s start with the more obvious takeaways, and keep in mind that the broad market, represented by SPY, lost 6.1% from 8/3 through 8/31, and was virtually flat over the trailing one-year period:

• The High-Tech Portfolio, a long-time outperformer in the market, fell less than half the broad market, showcasing that sometimes leaders can weather a downturn better than most.

• The Sky is Falling, Black Swan Hyperinflation, and GLD-Free Gold Bug Portfolios generated positive returns during a serious market rout.

Drumroll for the surprises please….

• The Baby Boomers, an even more impressive outperformer than High-Tech, fell nearly as much as the broad market, showcasing that sometimes leaders can get punished just as much, if not more, than the broad market. The reason is simple: investors who had amassed sizeable profits, in light of the sectors’ outperformance, used the broad market sell-off as an opportunity to take profits, which in turn was compounded by traders and computers selling as well.

• The Mining and Energy Bull Portfolios, long-time laggards, barely fell lower during a period when everything was slaughtered. The lesson here is for contrarians: sometimes your “deep value” pick can weather a storm better than most would expect. You always have to keep in mind how beaten down a security is from a longer term perspective before heading into a specific event or period of heightened volatility.

When considering the relative performance of long-time leaders and laggards during a broad-based market pullback, there are no obvious trends, which truly defines a high-volatility environment. That is to say, sometimes leaders can outperform the broad market during a sell-off, and sometimes they can be surprisingly vulnerable; and vice a versa for laggards.
