Long ago, I used to think naively that absolute stock price Is the greateat determinant when buying a stock. This is wrong. A $1 share can be expensive ( when it's intrinsic value is 0) whereas a $100 share is cheap when its worth is say, $200. So now wiser, I'd buy the $100 share. Also, don't buy trashy stocks but buy only the highest quality stocks eg, CRM, google, unh, Msft etc. Buy only when you have researched them & do your due diligence.
Many of the magnificent 7 eg meta, googl & amzn have dipped a fair bit despite solid Q3 earnings. Mr Market is irrational and wrong. These blue chips will always go higher in the long run. Ignore the noise and buy when they are still undervalued. Never sell in panic as long as these are solid companies.
