<prompt> Human: I graduated in May and now starting to get paychecks from work. I am in grace period till mid August so dont need to make any payments for another month. I am thinking about taking 4K from signing bonus and investing short term till August. I basically dont want extra 4K sitting in bank doing nothing. What type of investment do you recommend?  <response>: if you need it in a month, a savings account is exactly where it should be.
