(Wall Street Journal) — What present can you give a kid that will outlast the latest must-have toy or gadget? How about some stock in the company that makes it. You can jump-start a young person’s finances by giving him or her the gift of investing with stocks, bonds and mutual funds. Throw in some lessons on how the markets work — and the common pitfalls investors face — and you could end up giving them some financial savviness as well. Getting kids investing early “allows them to accumulate knowledge over time on what can be a complex topic,” says June Walbert, a certified financial planner based in San Antonio with financial-services firm USAA.
