Question on buying indiv down stocks instead of SPY when the SPY is still pretty consistent

Specifically, SPY is at same level as October 29. But the following stocks have taken big hits in that time period:

msft down 28% in 4 months

netflix 42% in 8 months

amazon 30 in 4 months

crowdstrike down 37% in 4 months

So my layperson thought process and tendency is to want to buy the dip on these solid or very solid stocks instead of buying SPY.

Does anyone else feel the same way? Would appreciate constructive feedback as I am not an expert.

Thank you all
