Single Stock: High risk, High reward. If you pick an individual winner early in its lifecycle like buying $Alphabet(GOOG)$ at its IPO and hold it till now, your personal wealth can completely outpace the broad market benchmark.
However the single stock route leaves you completely exposed to a single point failure like an unexpected earnings miss, can cause the stock to lose double digit value in a single session.
ETF: When you buy a thematic ETF like $Roundhill Memory ETF(DRAM)$ , you bypass individual company failures. DRAM packs its weight into memory titans, allowing you to profit from a global chip shortage without the worry if one company hits a snag.
Ultimately it is up to an individual's risk appetite. There is no right or wrong in investing.
