Stocks were indicated marginally higher on Friday, but this as after the Dow Jones industrials and S&P 500 hit all-time high closes on Thursday. International markets were also higher on Friday, but many international and emerging markets are still very far away from their all-time highs. As many investors have seen lower upside from buying on market pullbacks than in prior years, they have to consider how they want to have their investments positioned for the rest of 2018 and as 2019 approaches.
