During Tuesday's trading on Wall Street, investors were focused mainly on the results of companies. As a result, indices DJIA and S&P500 ended the day with increases of about 0.3 percent and the Nasdaq Composite slipped by 0.4 percent. The market was supported by rise in commodity prices, in technological sector investors reacted to the weak performance of IBM.

Night fall of contract for the S&P500 indicates that moods are worse now than at the time of closing of trading on European indices. It is therefore expected that yesterday's rise in the DAX (+2.3%) will take this morning some form of correction, which will most likely echo in the Polish market in the form of corrective stance on the WIG20.

Raw materials markets today are reassessing both oil and copper, both being direct drivers of the WIG20 performance. Yesterday's 1 percent increase, had healthy dynamics of raw materials as one of the major contributors. Therefore, correction in raw materials should reflect in a correction of WIG20 at opening.
