NEW YORK (TheStreet) -- Today offered a few important reminders for the studious investor, Jim Cramer told his Mad Money viewers Friday. It also rewarded those individuals who bet on several major technology companies. This is a market with opportunities for individuals who take the time to analyze companies, events and economic trends.

A strengthening dollar hasn't created havoc. Many investors were fearful that the stronger dollar would hurt the market. But these concerns were unjustified.

There's no indication that interest rates will have to go higher soon. Interest rates may not be going much higher, as inflation remains under control.

Improvement overseas impacts American companies. Buoyed by U.S.-style stimulus packages, the European economy is improving. That will help overseas growth at multinational U.S. firms.

Cramer reminded viewers to buy stocks they liked at discount prices. Naysayers who predict that the bull market is in its end stages may help create those more favorable prices -- witness Janet Yellen's pronouncements earlier this week.

There were positive earnings in the tech sector. Tableau Software (DATA) headed the list. The data-mining company is coming off a spectacular first quarter in which it beat earnings estimates and reported year-over-year growth of nearly 75%. Cybersecurity experts Cyberark Software (CYBR) also recorded a strong first-quarter performance.

Many major companies have reported earnings for their most recent quarter, but there are several important firms that will weigh in next week. Cramer said to look at Actavis (ACT), a pharmaceutical/healthcare firm that has been performing well in recent months. The stock rose nearly 2% today. Online real estate database Zillow Group (Z), retail chains J.C. Penney (JCP), Kohl's (KSS) and technology giant Cisco (C) will also report. Cramer said that how these companies perform may determine larger market trends.
