Stocks were indicated to open marginally higher on Tuesday, which would make a four-day Dow Jones industrials rally, if the gains hold. Earnings season is now about 90% of the way to its end, and more than 70% of the companies exceeded expectations. Still, investors have noted that the stock market volatility in 2018 has been less rewarding for those who have continued to buy on every dip than had been the case for several years. Many investors also are trying to decide how they want their investments positioned ahead of the midterm elections and given international trade concerns.
