I was just testing out Portfolio backtester from here and did not feel very good when investing in SPY for example over a long period of time. I tried 3 portfolios with starting amount 10,000$ and 2,500$ invest each month as follows:
– Portfolio 1: 100% SPY
– Porfolio 2: 100% QQQ
– Portfolio 3: 25-25-25-25% AAPL, AMZN, GOOG, MSFT
– Portfolio 4: equal weight GOOG, AMZN, NFLX, AAPL, MSFT, NVDA, AMD
Results were after 15 years of investment horizon (Jan 2008 – May 2023):
– SPY: $1.4 Million
– QQQ: $2.3 Million
– Big Tech: $4.9 Million
– Full Tech + Semis: $12.1 Million
My question right now is that which path should I continue to put money into (2,500$ each month) for the best possible returns over 15 years?
– SPY each month
– Change SPY to QQQ for somewhat better results
– Own tech portfolio: GOOG, AMZN, NFLX, AAPL, MSFT, NVDA/AMD, META (each equal weightage)
