A vanguard etf is being reported as a potentially lucrative investment opportunity, with some outlets suggesting it could set an investor up for life. The etf in question may be the vanguard total stock market etf or the vanguard s&p 500 etf, as both are mentioned in the coverage. Investing a certain amount of money, such as $1,000 or monthly contributions of $200 or $300, could potentially yield significant returns over time, possibly even over $1 million.
