There are two paths to purchasing stocks:
First, direct from the issuing company or its transfer agent.
Or, second, through a registered representative, also known as a stockbroker.
In either case you’ll have to open an account to hold your purchases.
That done, you can acquire any number of pieces of the world economy.
These can be shares of stock in an individual enterprise, bonds funding enterprises (or governments), or you can become a partner in an entity.
Alternatively, you can purchase collections of stocks, and or bonds, or partnerships. These are sold as funds, trusts, or exchange traded products.
My specialty is dividend stocks. I rate them thus:
The Dividend Dogs Rule
The “dog” moniker is earned in three steps: (1) any stock paying a reliable, repeating dividend (2) whose price has fallen to a point where its yield (dividend/price) (3) has grown higher than its peers (in any sector, index, portfolio, or collection), is so tagged. Thus, the highest yielding stocks in any collection become known as “dogs.”
