Isn't it a tedious and mundane task to have to spend hours per day or hours per week analyzing various stocks, reading financial reports, comparing companies' P/E ratios, and following the industry news to determine which stocks to buy and which stocks to sell? Stock trading, and particularly day trading, for that matter, hardly seem like passive sources of income, do they? If they were truly "passive", then we wouldn't have to do all this work! We should be making money on autopilot! That's where computer software comes in handy.
Nowadays, there are computer software programs that are designed to analyze various stocks and make stock recommendations for you, based on cold, hard numbers, statistics, trends, patterns, and umpteen other variable data points.
In a matter of seconds, minutes, or hours (depending on how many stocks you want the software to look at, and how much computing power your computer has), stock analyzing software can perform some serious number crunching and make a bold "prediction", which is really more of an extrapolation, as to which stocks on the market are on the verge of experiencing a significant surge in price in a short time horizon.
Can you blindly trust a computer program to issue a "hot stock alert"? Obviously nobody, not a human being, and certainty not a machine, can account for the geopolitical influences that govern the world economy.
But you can leverage the resources of stock analyzing software to help you make sound investing decisions, based on mathematical probability.
