Should stock investors sell now? It’s been a good year for stocks — the S&P 500 has returned 5.7% this year despite the drop on Friday. But has it been too good? Seven-and-a-half years into the bull market, valuations are high and we see little upside in stocks between now and year-end. Friday’s more than 2% drop was the S&P 500’s first drop of more than 1% since just after the Brexit vote on June 27, 2016, so we were due for a pullback. Add to that, September is a seasonally weak month. All of that begs the question, should you sell now? Certainly taking some profits or rebalancing portfolios according to your regular plan is prudent. But in this commentary we lay out reasons why selling now may not be the best move.
