Is a september Market Crash Something I Should Be Worried About? Need Advice

Hello everyone, I’m new to investing and would appreciate any advice that people might have.

After taking a look at my portfolio, I figured out that I am highly concentrated in tech and growth, where META, GOOGL, and AMD take up majority of my portfolio.

Also, there has been quite a bit of talk about how September is historically bad for the stock market and how there may be a possibility of correction/crash in September.

Now, since I am new, I don’t really know what to do about it.

What do you guys think I should do?

Do I:

Ignore the whole September crash talk and leave my money in there?

Cash out some profits from META/GOOGL/AMD and leave rest invested?

Lower individual stock exposure and invest in SCHG?

Invest somewhere other than tech/growth?
