You might hear experienced investors talk about the concept of a "wide moat," especially if you're reading anything about Warren Buffett's investment style.

Some scammers will buy up a ton of some near-bankrupt, almost lifeless penny stock, then use lies and exaggerations to push the share price much higher. They might say the company is about to get some huge business deal with Google or their neighbor just struck gold in their similar mine, or they are going to land a major FDA clearance. That typically helps increase the value of the penny stock, which creates a profit for the promoter or scam artist. As the shares increase in value, they sell their holdings. These shares usually collapse back down to near-worthless status once the promoter has taken their profits and moved on.

You can buy stock directly using a brokerage account or app. Other options exist for those who are employed—either a 401k plan or a 403b plan if you work for a non-profit. Then there's the IRA—be it a Traditional IRA, Roth IRA, Simple IRA, or SEP-IRA account. You can also set up a direct stock purchase plan or dividend reinvestment plan (DRIP). Each type of account has different tax implications.
In most cases, your broker will charge a commission every time that you trade stock, either through buying or selling. Trading fees range from the low end of $2 per trade but can be as high as $10 for some discount brokers. Some brokers charge no trade commissions at all, but they make up for it in other ways.
