I am in my mid 20's and thought that I needed to start accumulating wealth (besides savings).
I am thinking of accumalting a few stocks.
What platforms do u regard as the best for such activity?
They offer a number of no-load mutual index funds which you can dollar cost average into. A good choice for new investors.
Your bigger decision is whether to go active or passive. For 90% or more of the population in your situation, the best thing to do is buy a Target Retirement Date fund, contribute to it regularly, and gradually build wealth the safe and boring way.
There is a very small percentage of people who can genuinely beat the market. If you're asking the question in OP, you're not there yet. Go back to option 1, park your money there, and do a lot of reading. "Where Are the Customers' Yachts" and "You Can Be a Stock Market Genius" (terrible title, great book) are good places to start.
