Stocks were posting strong gains in early trading today, following three days of losses and the biggest one-day drop in the S&P 500 since February.

Technology stocks, which were hurt hard earlier in the week, were among the bigger gainers in early trading. Apple, Microsoft, Facebook and Amazon were all up 1% or more.

The S&P 500 Index was up 1.2% as of 9:05 a.m. Central. The Dow Jones Industrial Average was up 1.2% as well while the tech-heavy Nasdaq Composite was up 1.5%. It’s not uncommon for markets to reverse direction after sharp gains or losses over a period of days as investors reassess markets and pause during period of volatility.

But investors have had things to be concerned about. Last week’s jobs report was showed fewer employers hiring than had been expected, and today the government reported that wholesale prices jumped 0.6% last month, driven by higher costs for services and food. That was more than expected and the latest indication that inflation pressures are mounting.

Rising prices reflect growing economic activity after last year’s global shutdown to fight the coronavirus pandemic. However investors worry inflation might disrupt the recovery or prompt central banks to withdraw stimulus and near-zero interest rates.
