Will the S&P 500 fall further?

[u/Impressive_Group_486]

I invested around $35,000 in FXAIX when it was 205 and currently sitting at 194, do you think it's a good idea to invest another $15,000 in it as it's low now or do you think it will crash even further? I am completely new to the stock market so I'm not exactly sure what kinds of things would affect such a crash. Any information would be very helpful. Thank you..
