Fortunately, at least in the United States, investors do not have too much to worry about when it comes to account security. This is especially true when choosing a brokerage that is large, well known, and properly regulated. Every website should be secured with SSL encryption, and client data should be stored in secure servers. Dual-factor authentication and Face ID are other security protocols quickly growing in popularity.
The use of borrowed money “levers” or exaggerates the result of price movement. Suppose the stock moves to $200 a share and you sell it. If you had used your own money exclusively, your return would be 100% on your investment [($20,000 -$10,000)/$10,000]. If you had borrowed $5,000 to buy the stock and sold at $200 per share, your return would be 300 % [(20,000-$5,000)/$5,000] after repaying the $5,000 loan and excluding the cost of interest paid to the broker.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
