If you had $7.5k to invest tomorrow, what would you do in this current market?

I have $7.5k free up finally that I am ready to invest into the market. I am new to all of this, but seeing that money literally doing nothing in my bank account isn't good either. I would be lying if I wasn't kicking myself for not doing this a month earlier at the start of April but I guess I need to start sometime. I am thinking of putting in 50% into VOO, 25% into SPY, and then allocate the other 25% into other stocks. I am nervous in the MU runup, but I live close-by to one of their new construction projects and man....it is massive. I really don't know where to start on research into companies, but would like to hear out advice from others. Edit for more info: Looking to sink it and forget about it for about 2-4 years.
