The stock market kept gaining ground, and the Dow and S&P 500 climbed further into all-time record-high territory in the wake of strong earnings reports from several influential companies in the U.S. economy. The negative impact from the U.K. Brexit vote hasn't yet materialized, and some now believe that the economic effects from a potential British departure from the European Union won't be as bad as previously feared

In response, major market benchmarks climbed between roughly a quarter- and a half-percent, but some individual stocks still missed out on the gains. Among the poorer performers on Wednesday were Interactive Brokers (IBKR -1.58%), Exponent (EXPO -1.85%)and Ryerson Holding (RYI -2.63%).

Interactive Brokers can't satisfy investors with its earnings

Interactive Brokers fell 7% despite releasing second-quarter financials Tuesday night that showed better-than-expected earnings. The brokerage company reported adjusted earnings of $0.40 per share, but net revenue fell almost 5% from the year-ago quarter.

Profit margin on market-making activity plunged, but the number of customer accounts, and the amount of equity in those accounts, rose considerably compared to last-year's quarter. Nevertheless, even though many investors reacted negatively to the short-term results, market making is a volatile activity, and it's likely that Interactive Brokers will bounce back from what has been a difficult period for the financial markets so far in 2016.

Exponent takes a hit, cuts guidance

Exponent dropped 11% after its second-quarter financials fell well short of what investors had expected to see. The engineering and scientific consulting firm saw revenue decline 3%, contributing to an 11% drop in net income. Earnings of $0.38 per share missed the consensus forecast by $0.05, and the company's environmental and health segment was hit especially hard, with sales declining 20% year over year.

Reduced spending in the oil and gas industry and mergers among industrial chemicals companies cut demand, but CEO Dr. Paul Johnston noted that the issues weren't unique to Exponent, and that he expected the company to bounce back in the long run. Traders weren't willing to be that patient, especially because Exponent reduced its 2016 guidance to project weaker revenue and operating margin for the year.

Ryerson sells some stock

Finally, Ryerson Holding lost 13%. The metals processor and distributor announced the pricing for a secondary offering of its common stock late Tuesday, selling 5 million shares of stock at $15.25 per share. That price was about $1 per share lower than where Ryerson closed Tuesday, and the share price fell even more dramatically, punishing those who participated in the offering.

The company expects to use the proceeds to pay off debt, including senior notes due in 2018 that carry an interest rate of 11.25%. One bond-ratings agency touted the move as being positive from a credit standpoint, but dilution is never something that shareholders like to see during a cyclical downturn.
