What should investors keep an eye out for in this market?

Jim Cramer breaks down what he's looking at--which includes the S&P Oscillator--but also what investors can expect as the week goes on. 

This week is the busiest week for earnings this season, with over 160 companies reporting this week alone.

On Monday, companies such as Hasbro HAS reported--and disappointed the market. Tuesday morning saw companies such as McDonald's (MCD - Get Report) , 3M (MMM - Get Report) , Lockheed Martin  (LMT - Get Report) and Caterpillar (CAT - Get Report) report. Caterpillar is also Real Money's stock of the day.

Wednesday will have earnings from companies such as Boeing (BA - Get Report) and Mattel (MAT - Get Report) . Cramer also broke down those two companies and his take can be found here.

Thursday is one of the biggest days this week. It'll have both Amazon and Alphabet reporting Thursday afternoon. TheStreet's Martin Baccardax discussed the two tech giants in TheStreet's Week Ahead podcast.
