I would definitely explore auto-investing as it works similar to the concept of dollar-cost-averaging and takes away the inertia and stress of timing the market. Stocks that would be great for auto-invest would be index-ETF like SPY or VWRA as indexes grow over time, so its probably the safest choice. Other stocks i would consider would be stable large cap stocks like $Microsoft(MSFT) as their prices are rather volatile but they look to have safe growth potential

However while auto investing is good for people who is busy and want to adopt dollar average method. There are people would prefer to read up the news about the companies and invest using own decision to maximise profit.
