I have about $250,000 available to invest in my Vanguard brokerage account, and I’m considering allocating $150,000 into VOO due to the recent dip in the market. However, I’m wondering if I should invest even more. Theoretically, if this investment were to become my sole source of income in 15 years, would that be a safe and sustainable strategy? How reliable is VOO in the long run, considering historical market trends, potential risks, and the impact of economic downturns? Should I diversify further to reduce risk, or would a concentrated investment in VOO still provide sufficient growth and stability over time?
